MIVA STUDY PACK — Auto & Motorbike Mechanic (English) Downloaded 2026-09-29. Free to pass on. Auto & Motorbike Mechanic — Lesson 1: Working as a mechanic today 7 minutes read EVERY VEHICLE KEEPS THE TOWN MOVING In towns and cities across Ghana, Nigeria, and Togo, transport is life. Market women rely on tricycles (Kekes) to carry goods from rural farms. Commuters hop into minibuses (tro-tros or Danfos) to get to work. Young workers rely on motorbikes (okadas or zémidjans) to weave through city traffic. When these vehicles break down, trade stops. As an auto and motorbike mechanic, your job is to keep these engines running safely. You are not just turning spanners. You are solving problems, keeping drivers safe, and supporting the local economy. FROM SIMPLE OKADAS TO MODERN CARS The mechanics trade has changed over time. Years ago, engines were simple mechanical machines. You only needed basic hand tools like spanners, screwdrivers, and pliers to fix most problems. Today, even small cars and modern motorbikes rely on electronic components. Here is what you will work on in a modern workshop: - Motorbikes and tricycles: Single-cylinder engines, carburettors or simple fuel injection, chain drives, and cable brakes. - Standard cars and vans: Four-cylinder engines, electronic control units (ECUs), sensors, hydraulic disc brakes, and complex wiring. - Light commercial vehicles: Small diesel or petrol trucks used for moving heavy farm produce or building materials. WHAT MAKES A SUCCESSFUL MECHANIC? Knowing how to replace a worn brake pad or set engine timing is only half the job. The best mechanics in your community succeed because of their professional habits. - Good communication: Explaining what is wrong in simple words so the vehicle owner understands what they are paying for. - Honesty: Replacing only the parts that are broken and giving fair prices in Cedis, Naira, or CFA. - Cleanliness: Keeping your hands, tools, and the customer's vehicle interior clean of grease. - Clear updates: Using WhatsApp to send short videos or photos of worn-out parts to customers before buying replacements. [Try this today] Take 10 minutes to sit near a busy road or market junction. Watch the vehicles passing by. Count how many motorbikes, tricycles, and passenger cars pass in five minutes. This shows you where the real demand for repair work lies in your neighborhood. PRACTICE QUESTIONS 1. Why is basic electronic knowledge important for mechanics today? A) Modern vehicles use sensors and computer controls alongside mechanical parts. B) Customers only pay mechanics who use expensive computers. C) Old hand tools no longer fit modern engine bolts. D) Electric motorbikes have completely replaced petrol engines. Answer: A — Modern cars and even modern motorbikes rely on electronic sensors and control modules. A good mechanic needs to understand both mechanical and electronic systems. 2. How can sending WhatsApp photos of damaged parts build your mechanic business? A) It allows you to charge double the market price for spare parts. B) It shows customers proof of the problem, building honesty and trust. C) It saves you from having to clean your hands after work. D) It removes the need to buy proper hand tools. Answer: B — Showing clear photos or videos of worn-out parts helps customers understand the repair needed, building strong trust and repeat business. ---------------------------------------- Auto & Motorbike Mechanic — Lesson 2: Workshop safety and tools 8 minutes read WHY SAFETY COMES FIRST IN THE SHOP An auto workshop is full of hazards. You work with heavy metal parts, flammable liquids like petrol, chemical solvents, acid inside car batteries, and heavy vehicles lifted off the ground. One small mistake can cause severe burns, crushed limbs, or eye injuries. A professional mechanic plans every job with safety in mind. Protecting your body ensures you can work and earn a living for many years to come. PERSONAL PROTECTIVE EQUIPMENT (PPE) Before picking up any tool, put on the right protective gear. Never work in plastic sandals or singlet tops. - Safety boots: Sturdy boots with reinforced toes protect your feet if a heavy engine block, wheel, or brake drum falls. - Eye protection: Clear safety glasses keep metal filings, battery acid splashes, and hot engine oil out of your eyes. - Work gloves: Tough gloves protect your hands from hot exhaust pipes, sharp metal edges, and chemical burns from solvents. - Cotton overalls: Heavy overall suits protect your skin from oil and prevent loose clothing from catching in moving fan belts. [DANGER: Never rely on a jack alone] Hydraulics can fail without warning. Never step under or put any part of your body under a vehicle supported only by a hydraulic jack. Always lower the vehicle onto solid steel axle stands or wooden blocks, and place wheel chocks against the tyres resting on the ground. ESSENTIAL HAND TOOLS EVERY MECHANIC NEEDS To start working, you need a collection of reliable hand tools. Buying quality tools saves money over time because cheap soft-metal tools strip bolt heads and snap easily. - Combination spanners: Open on one end and ringed on the other. Common sizes range from 8mm up to 19mm. - Socket set and ratchet: Allows you to remove bolts quickly in tight spaces without slipping. - Pliers: Combination pliers, needle-nose pliers, and circlip pliers for gripping wires, pins, and small clips. - Screwdrivers: Flathead and Phillips (crosshead) screwdrivers in different lengths. - Filter wrench: A strap or chain tool used to unscrew slippery oil filters safely. TAKING CARE OF YOUR TOOLS Dirty or oily tools slip out of your hands and cause injuries. At the end of every working day, wipe down each spanner and socket with a rag soaked in a little kerosene or cleaner. Store them neatly in a toolbox or on a wall rack so you can instantly see if a tool is missing. [Try this today] Inspect the footwear you plan to use for practical work. Check if the soles are slip-resistant and whether your toes are covered. If you do not have safety boots yet, find closed leather work shoes to protect your feet while training. PRACTICE QUESTIONS 1. What must you ALWAYS place under a lifted vehicle before crawling underneath it? A) A second hydraulic jack set to the same height. B) Axle stands or solid support blocks. C) Two spare rubber tyres piled flat. D) A heavy iron hammer under the bumper. Answer: B — Hydraulic jacks can drop suddenly if an internal seal leaks. You must always settle the vehicle weight onto solid axle stands or heavy blocks. 2. Why should you wipe oil off spanners and sockets at the end of every workday? A) To make the metal softer for the next day. B) To prevent tools from slipping out of your hands and rusting. C) Because clean tools allow engines to run faster. D) To change the size of the socket rings. Answer: B — Clean tools provide a firm grip, preventing slip injuries. Wiping off moisture and chemical residues also stops rust from destroying your steel tools. ---------------------------------------- Auto & Motorbike Mechanic — Lesson 3: How an engine works 7 minutes read THE POWER INSIDE THE ENGINE Whether you are fixing a small Bajaj okada, a TVS tricycle, or a Toyota taxi, the engine does the same main job. It turns liquid fuel into movement. It does this by burning fuel inside a tight metal space called a cylinder. Inside the cylinder, a metal plug called a piston moves up and down. That up-and-down movement turns a heavy metal shaft called a crankshaft. The crankshaft turns the gearbox, which turns the wheels to move the vehicle. THE FOUR-STROKE ENGINE CYCLE Most cars, tricycles, and modern motorbikes in West Africa use four-stroke petrol engines. This means the piston moves up or down four times to complete one full cycle of power. - 1. Intake stroke: The piston moves down inside the cylinder. The intake valve opens. Air and fuel are sucked into the cylinder. - 2. Compression stroke: The intake valve closes. The piston moves up. It squeezes the air and fuel mixture into a very small space at the top. - 3. Power stroke: The spark plug creates a hot spark. The air and fuel explode. The force of the explosion pushes the piston down hard. This gives the vehicle its power. - 4. Exhaust stroke: The exhaust valve opens. The piston moves back up. It pushes the burnt gases out through the exhaust pipe. [Safety around moving engine parts] Never put your hand near an engine while it is running. Fan belts, pulleys, and chain drives can catch your fingers or clothes in a split second. Keep loose shirts folded, tie back hair, and stay clear of moving parts. TWO-STROKE VS FOUR-STROKE ENGINES Some older okadas and small generators use two-stroke engines. A two-stroke engine completes the job in only two movements of the piston. It does not have oil in a separate sump. Instead, you must mix engine oil directly into the petrol tank. Four-stroke engines have separate oil inside the crankcase. They burn cleaner fuel and last longer, which is why almost all modern vehicles use them today. [Try this today] Find a parked motorbike or keke. Look closely at the engine block. Locate the cylinder head, the spark plug wire, and the exhaust pipe leading out. Trace where fuel enters and where exhaust smoke leaves. PRACTICE QUESTIONS 1. What happens during the compression stroke of a four-stroke engine? A) The burnt exhaust gases are pushed out of the tailpipe. B) The spark plug ignites the fuel to push the piston down. C) The piston moves up and squeezes the fuel and air mixture. D) Fresh air and petrol enter through the open intake valve. Answer: C — During compression, both valves stay closed while the piston moves up to squeeze the air and fuel mixture tightly before ignition. 2. Why must you mix oil with petrol in a two-stroke engine? A) Two-stroke engines do not have a separate oil sump to lubricate internal parts. B) The oil makes the petrol burn much faster inside the cylinder. C) Oil cleans the dirty exhaust pipe while you drive. D) It stops the battery from losing electrical charge. Answer: A — Two-stroke engines lack a separate oil chamber (sump), so oil must be mixed directly with petrol to lubricate the moving piston and crankshaft. ---------------------------------------- Auto & Motorbike Mechanic — Lesson 4: Oil, filters and routine service 8 minutes read WHY ROUTINE SERVICING MATTERS Engine oil is like the blood of a vehicle. Inside an engine, metal parts rub against each other thousands of times every minute. Without clean oil, this friction creates intense heat and grinds metal into dust. The engine will lock up and stop working. A routine service keeps an okada, keke, or car running smoothly. Servicing a vehicle on time saves the owner thousands of Naira, Cedis, or CFA francs in major repairs later. UNDERSTANDING ENGINE OIL Oil does three main jobs: it lubricates moving parts, cools hot engine parts, and sweeps away carbon dirt. Over time, heat breaks down the oil, making it thin, dark, and dirty. - Viscosity rating: Numbers like 20W-50 or 10W-40 show how thick the oil is. In hot climates, 20W-50 is common for older cars and motorbikes because it stays thick under heavy heat. - Monograde vs Multigrade: Monograde oil (like SAE 40) stays one thickness. Multigrade oil (like 20W-50) adjusts better to temperature changes. - Synthetic vs Mineral: Mineral oil comes straight from refined crude oil. Synthetic oil is engineered in a lab to last longer under hard work. THE THREE KEY FILTERS During a full service, you check and replace filters to keep dirt out of sensitive engine components. - Oil Filter: Traps metal filings and carbon flakes as oil circulates. Change this every time you change engine oil. - Air Filter: Traps dust, dirt, and sand before air enters the engine. Dusty roads in West Africa clog air filters quickly. A dirty air filter wastes fuel. - Fuel Filter: Traps rust and water from petrol or diesel tanks before fuel reaches the injectors or carburetor. [Hot oil and environmental safety] Engine oil gets extremely hot. Always let the engine cool down slightly before opening the drain plug, or hot oil will burn your hands. Never dump waste oil into open gutters, soil, or streams. Collect used oil in a container and sell or give it to recycling collectors. BASIC STEPS OF AN OIL CHANGE Follow these steps carefully every time you change oil on a vehicle: - 1. Park on flat ground and turn off the engine. - 2. Place a drain pan under the oil sump bolt. - 3. Unscrew the drain bolt with the correct size spanner. Let dirty oil drain out completely. - 4. Remove the old oil filter using a filter wrench. Lightly coat the rubber seal of the new filter with fresh oil and screw it on hand-tight. - 5. Put the drain bolt back with a good washer and tighten it firmly, but do not strip the threads. - 6. Pour in the correct volume and type of fresh oil through the filler cap on top. - 7. Pull out the dipstick, wipe it clean, put it back in, and pull it out again to check the level. The oil mark should sit between the MIN and MAX lines. [Try this today] Locate the dipstick on a car or motorbike engine. Pull it out, wipe it clean on a rag, reinsert it fully, and pull it out again. Practice reading the oil level and looking at the color of the oil on the rag. PRACTICE QUESTIONS 1. Why must you replace the air filter regularly on vehicles driven on dusty roads? A) A clogged air filter blocks airflow, causing the engine to burn too much fuel. B) Dust in the air filter stops the battery from charging properly. C) The air filter controls the pressure inside the hydraulic brake lines. D) Dust makes the oil drain bolt fall off while driving. Answer: A — When an air filter gets full of dust, less air reaches the engine. The engine burns more fuel to make up for the missing air, wasting fuel and causing bad smoke. 2. Where should the oil level show on an engine dipstick after refilling? A) Way above the maximum line to make sure there is plenty of oil. B) Right at the very bottom tip of the stick. C) Between the MIN and MAX marker lines. D) Oil should never touch the dipstick. Answer: C — The correct oil level must sit between the minimum (MIN) and maximum (MAX) indicator lines. Too little oil damages engine parts; too much oil damages seals. ---------------------------------------- Auto & Motorbike Mechanic — Lesson 5: Brakes, tyres and suspension 8 minutes read STOPPING AND SMOOTHING THE RIDE A mechanic must make sure vehicles can accelerate and roll smoothly, but stopping safely is even more critical. Brakes, tyres, and suspension work together as a single team. If any one of these three fails, the driver loses control. In West Africa, roads often have deep potholes, heavy dust, loose gravel, and sudden rains. Knowing how to maintain these three systems keeps your customers safe on every journey. HOW BRAKE SYSTEMS WORK Brakes slow down a vehicle by turning motion into heat through friction. Motorbikes, tricycles like Keke Napep or aboboyaa, and cars use two main types of brakes: - Disc brakes: A hydraulic caliper squeezes flat brake pads against a metal disc (rotor) that turns with the wheel. Disc brakes cool down quickly and give strong stopping power. - Drum brakes: Piston cylinders or mechanical cables push curved brake shoes outward against the inside of a metal drum attached to the wheel. These are common on okada rear wheels and older car rear axles. Hydraulic brake systems use special brake fluid (usually DOT 3 or DOT 4) to carry force from the brake pedal or handlebar lever down to the wheels. Over time, brake fluid absorbs water from humid air. This lowers its boiling point and causes internal rust. If air gets into the brake lines, the pedal or hand lever feels soft and spongy because air compresses under pressure while fluid does not. To fix a spongy brake, you must bleed the brakes. This means opening the bleeder valve at the wheel while pumping fresh fluid through until no air bubbles come out. [Safety First: Secure Vehicles Before Working Underneath] Never put any part of your body under a vehicle supported only by a hydraulic or scissor jack. Jacks can fail instantly. Always lower the car or tricycle onto solid axle stands or heavy timber blocks on flat ground before removing wheels or working on brakes. READING TYRE HEALTH Tyres are the only part of a car or motorbike touching the road surface. Good tread channels water away so the rubber can grip wet asphalt during heavy downpours. Check these four key areas whenever a vehicle comes to your workshop: - Tread depth: Tyre tread should never drop below 1.6 millimetres. Smooth tyres ('slick' tyres) slide easily on wet dirt or asphalt. - Air pressure (PSI): Always measure pressure when the tyre is cold. Under-inflated tyres wear out quickly on both outer edges and increase fuel consumption. Over-inflated tyres wear out only in the center and give a harsh ride. - Uneven wear: If one edge of a tyre wears down faster than the other, the wheel alignment is crooked or suspension parts are bent. - Tyre age code: Look for a 4-digit number stamped on the tyre sidewall. For example, '1222' means the tyre was manufactured in the 12th week of 2022. Tyres older than five years dry out, crack, and can burst at high speeds. SUSPENSION PARTS AND COMMON FAULTS Suspension keeps the tyres pressed firmly against the road while protecting passengers and frame parts from severe shocks. Key parts include shock absorbers (dampers), springs (coil or leaf springs), and rubber bushings. When shock absorbers wear out, fluid leaks down the outside of the shock body. A vehicle with bad shocks bounces repeatedly after hit hitting a pothole, sways in turns, and takes much longer distance to stop during hard braking. Rubber bushings cushion the joints where control arms meet the frame. When rubber bushings dry out or crack, you will hear loud clunking or knocking noises over rough ground. [Try this today] Inspect three different parked vehicles today (a motorcycle, a keke, and a car). Check the tyre sidewalls for the 4-digit date code. Look at the tread wear pattern across the tire width to see if it is wearing evenly or unevenly. PRACTICE QUESTIONS 1. Why does a brake pedal feel soft or 'spongy' when squeezed or pressed? A) The brake pads are brand new B) Air bubbles are trapped inside the hydraulic brake fluid lines C) The tyre air pressure is slightly too high D) The brake disc is cold Answer: B — Air compresses when squeezed under pressure, unlike fluid. Trapped air bubbles in hydraulic lines make the lever or pedal feel soft and spongy. 2. What happens to a tyre that is operated with under-inflated air pressure (too low PSI)? A) The center of the tread wears out faster than the rest B) The vehicle uses much less fuel C) The outer edges of the tread wear out faster and fuel usage goes up D) The tyre sidewall becomes completely immune to punctures Answer: C — Low tyre pressure causes the tyre to sag, pushing heavy weight onto the outer shoulders. This wears the edges down quickly and increases rolling resistance, wasting fuel. ---------------------------------------- Auto & Motorbike Mechanic — Lesson 6: Batteries, lights and wiring 8 minutes read THE ELECTRICAL HEART OF THE VEHICLE Every modern motorcycle, tricycle, and car relies on electricity to start the engine, run lights, power horn signals, and operate fuel pumps. Auto electrical work frightens many beginner mechanics, but the basic rules are logical once you understand how current flows. Vehicles use a Direct Current (DC) system powered by a 12-volt battery (or 6-volt on some small older bikes). The electrical system has three main jobs: - Starting: Storing chemical energy in the battery to turn the starter motor. - Charging: Generating electrical power using an alternator (cars) or stator coil (motorbikes/kekes) to refill the battery while the engine runs. - Circuits: Sending power through insulated copper wires, switches, and fuses to run components like lights, horns, and wipers. MAINTAINING AND TESTING BATTERIES Lead-acid batteries contain lead plates submerged in sulfuric acid solution. Battery terminals often develop white or light blue powdery crust. This corrosion acts like insulation, blocking electric current from reaching the starter motor. To clean corroded terminals, pour warm water mixed with baking soda over the battery posts and scrub them clean with a stiff wire brush. Dry the posts completely and apply a light coat of grease or petroleum jelly to block moisture and stop corrosion from returning. You can test battery health using a digital multimeter set to 20V DC: - Engine OFF (Resting voltage): A fully charged healthy battery reads 12.6 Volts or higher. A reading of 12.0 Volts means the battery is almost completely flat. - Engine RUNNING (Charging voltage): With the engine idling around 1500–2000 RPM, the reading should jump to between 13.8 Volts and 14.4 Volts. If voltage stays at 12.5V or drops, the charging system (alternator or voltage regulator) is faulty. [Safety First: Protect Against Battery Acid and Sparks] Lead-acid batteries produce invisible hydrogen gas while charging, which can explode if sparked. Wear protective safety glasses when working near batteries. Always disconnect the negative (-) ground cable first before unbolting electrical parts. If you disconnect the positive (+) cable first and your metallic spanner touches the metal chassis, you will create a severe short-circuit spark. FUSES, SWITCHES, AND GROUND CONNECTIONS A fuse is a delicate safety guard inside an electrical circuit. It contains a thin wire strip engineered to melt and break the circuit if electrical current becomes dangerously high (such as during a short circuit). This melting stops copper wires from overheating and catching fire. Fuses are rated in Amperes (e.g., 10A, 15A, 20A). Never replace a blown fuse with one that has a higher Amp rating. Never wrap silver cigarette foil, wire strands, or copper nails across a blown fuse holder. Doing so removes safety protection and causes vehicle fires! Remember this golden rule of auto electrics: electricity must complete a full loop from the battery positive terminal, through the switch and load (like a headlight bulb), and back through the metal body or frame to the battery negative terminal. More than 70 percent of electrical problems on okadas, kekes, and cars are caused by loose, dirty, or rusted ground (earth) connections where wire eyelets attach to the metal frame. If a tail light blinks weakly or acts crazy when you turn on an indicator, check for a rusty ground connection first. [Try this today] Take a digital multimeter or a simple 12V test light. Turn a motorbike or car ignition ON. Practice touching the negative black lead to clean metal on the engine frame and probing both top test points on a blade fuse to check if power is flowing smoothly. PRACTICE QUESTIONS 1. What should a multimeter read across battery terminals when an engine is running with a healthy charging system? A) 10.0V to 11.5V B) 13.8V to 14.4V C) 20.0V to 24.0V D) Exactly 6.0V Answer: B — When the engine is running, the alternator or stator must supply a higher voltage (13.8V - 14.4V) than the resting battery voltage to push electrical current back into the battery and charge it. 2. Why is it dangerous to replace a blown fuse with a piece of copper wire or foil? A) It causes the battery to overcharge instantly B) It turns all warning lights off permanentely C) It removes overload safety protection and can overheat wiring to cause a fire D) It makes the vehicle engine burn excess engine oil Answer: C — A fuse is designed as a weak point that breaks safely during excess current. Bypassing it with thick wire or foil allows high current to melt wire insulation, leading to short circuits and vehicle fires. ---------------------------------------- Auto & Motorbike Mechanic — Lesson 7: Finding faults step by step 8 minutes read WHY SYSTEMATIC FAULT-FINDING MATTERS When an okada, keke, or car stops working, many young mechanics start replacing parts right away. They guess that the problem is the spark plug, buy a new one, and find out the engine still will not start. Guessing wastes your customer's money and ruins your reputation. A great mechanic acts like a detective. You follow a clear step-by-step system to find the exact problem before spending any money on parts. STEP 1: ASK THE DRIVER THE RIGHT QUESTIONS Your investigation begins by talking to the driver. Drivers know how their vehicle usually feels and sounds. Listen carefully to their answers and ask specific questions instead of general ones. - When did the problem start? Was it sudden or did it happen slowly over a few weeks? - Does the noise or vibration happen only when driving fast, turning, or applying brakes? - Does the engine struggle when it is cold in the morning, or only after driving in heavy heat for an hour? - Has any other mechanic worked on the vehicle recently? If a customer sends a WhatsApp voice note saying 'my car is making a bad sound', ask them to describe where the sound comes from and whether it sounds like grinding, squeaking, or knocking. STEP 2: INSPECT WITH YOUR SENSES Before touching any tools, use your eyes, ears, nose, and hands to inspect the vehicle. Make sure the vehicle is parked on flat ground with the engine turned off and the parking brake pulled before you start. - Look: Check for oil puddles under the frame, loose wires near the battery, cracked rubber belts, or low brake fluid in the reservoir. - Listen: Start the engine safely and listen. A high squeal often means a loose fan belt. A heavy metallic knock inside the engine block signals serious internal wear. - Smell: A sweet chemical smell usually indicates leaking radiator coolant. A sharp burnt smell can mean a slipping clutch or hot brake pads. - Touch: Gently feel wheels after a short drive. If one rim is extremely hot, the brake calliper on that side might be stuck. [Workshop Safety Warning] Never put your hands near moving engine belts or hot exhaust pipes while the engine is running. Always support a raised vehicle with solid axle stands—never rely on a hydraulic jack alone when looking under a car or keke. STEP 3: TEST FROM SIMPLE TO COMPLEX Always test the cheapest and simplest causes first. If a motorbike engine will not turn over, check the basic requirements for combustion: fuel, air, spark, and compression. First, check if there is petrol in the tank and that the fuel valve is open. Second, check if the battery has enough charge to turn the starter motor. Third, remove the spark plug to see if it is dirty or wet with fuel. Only if these simple checks pass should you open the engine cover or test expensive electrical parts like the ECU or ignition coil. STEP 4: CONFIRM YOUR DIAGNOSIS AND TEST THE FIX Once you believe you have found the fault, explain it clearly to the owner before replacing anything. After fitting the new part or fixing the loose wire, test the vehicle again under real conditions. Drive it on a short rough road or up a hill to ensure the problem does not return. [Try this today] Find a motorbike, keke, or car nearby. Practice the 'Four Senses Check'. Spend five minutes looking closely at the engine bay for loose hoses, sniffing for fluid leaks, and listening for unusual sounds. Write down three things you observed. PRACTICE QUESTIONS 1. What is the very first thing you should do when a customer brings a broken vehicle to your shop? A) Take the engine apart immediately to see what is inside. B) Buy new spark plugs and a new battery. C) Ask the driver specific questions about when and how the problem happens. D) Tell the customer how much the repair will cost without looking. Answer: C — Talking to the driver first helps you understand the symptoms, saving you time and preventing unnecessary work. 2. Why should you test simple causes before complex ones during fault-finding? A) Simple causes are rare and usually wrong. B) It saves time and prevents buying expensive parts that are not needed. C) Complex parts cannot be tested with basic workshop tools. D) Simple tests require taking the entire vehicle apart. Answer: B — Checking basic items like fuel, battery charge, and loose wires prevents wasting time and money on major repairs when a simple fix is all that is needed. ---------------------------------------- Auto & Motorbike Mechanic — Lesson 8: Honest pricing and loyal customers 8 minutes read TRUST IS YOUR MOST VALUABLE TOOL In the auto mechanic trade, technical skill gets you started, but honesty builds your business. Many vehicle owners feel nervous when visiting a workshop because they fear being cheated or charged for fake repairs. If customers know you are truthful, they will bring their cars, okadas, and kekes to you for years. They will also recommend you to their friends, family, and local transport unions. HOW TO CALCULATE A FAIR QUOTE A good price protects both you and your customer. It covers your real costs and pays you fairly for your time, without overcharging. Every price quote should be split into three clear parts: - Spare parts: The actual price of buying the replacement part from a reliable supplier. - Transport and sourcing: The small expense of taking a tro-tro or okada to the spare parts market to buy the item. - Labor fee: The money you charge for your time, knowledge, and physical effort. For example, if new brake pads for a Toyota Corolla cost 12,000 Naira, transport to the market costs 1,000 Naira, and your labor fee is 5,000 Naira, the total price is 18,000 Naira. Write these items down separately on paper or in a WhatsApp message so the customer sees exactly where their money goes. EXPLAINING PART QUALITY TO YOUR CUSTOMER The market offers different grades of spare parts: original (OEM), good quality aftermarket parts, and cheap copy parts. Never buy cheap fake parts and charge the customer for original parts. Be honest about options. Tell the customer: 'An original Honda brake cable costs 40 Cedis and will last two years. An aftermarket cable costs 25 Cedis and may last one year. Which one fits your budget today?' Let them decide based on clear facts. [Safety Warning on Cheap Parts] Never install dangerously low-quality counterfeit parts for safety-critical systems like brakes, steering racks, or wheel bearings. If a customer insists on using unsafe parts, politely decline the job to protect their life and your professional reputation. HANDLING UNEXPECTED EXTRA PROBLEMS Sometimes you agree to fix a simple leak, but when you open the engine, you discover a cracked timing belt or worn water pump. Never fix extra costly items without asking the customer first. When you discover an extra problem: - Stop work immediately on that section. - Take a clear photo or short video of the damaged part with your phone. - Send the picture to the customer on WhatsApp or call them to explain the situation clearly. - Tell them the extra cost for parts and labor, and wait for their approval before continuing. SHOW THE OLD PARTS AFTER FINISHING When a job is done, place all worn-out parts you replaced (such as old oil filters, burnt spark plugs, or thin brake shoes) in a clean box. Show them to the customer when they come to pay and pick up their vehicle. This simple habit proves that you actually replaced the parts you billed them for. [Try this today] Practice writing a clear quote for a routine service on a motorbike or car. Create three lines: Parts cost, Sourcing transport, and Labor fee in your local currency (Naira, Cedis, or CFA). Show it to a mentor or fellow learner to see if it is easy to read. PRACTICE QUESTIONS 1. Why should you list spare parts, transport, and labor separately on a customer's quote? A) It makes the final price look larger so you can make more profit. B) It shows transparency so the customer understands what they are paying for. C) It allows you to hide extra fees inside the parts cost. D) Mechanic laws require all quotes to have at least five separate items. Answer: B — Breaking down the costs shows honesty and helps build long-term trust with vehicle owners. 2. What should you do if you discover an extra broken part while repairing a vehicle? A) Fix it secretly and add the cost to the final bill without telling the customer. B) Ignore the broken part and finish only the original work. C) Stop work, take a photo, explain the problem and extra cost, and ask for permission before continuing. D) Keep the vehicle in your shop until the customer pays double. Answer: C — Communicating unexpected costs and showing photographic evidence before doing extra work prevents disputes and proves your integrity. ---------------------------------------- Auto & Motorbike Mechanic — Lesson 9: Build Your Professional Profile 10 min read OBJECTIVE: Set up a simple, honest professional presence online so employers and customers can find and trust you. Before someone hires you or buys from you, they often look you up. A professional profile is simply a clean, honest page that answers three questions: who are you, what can you do, and how can someone reach you? You do not need to be famous or have a computer. A phone and one good photo are enough to start. START WITH WHAT IS FREE - WhatsApp Business — free app. Add your trade, working hours, location and a short catalogue of your work or services. Many customers in West Africa will find you here first. - Google Business Profile — free. If you have a shop, workshop or stall, this puts you on Google Maps so people nearby can find you. - LinkedIn (free Basic account) — useful if you want office, NGO or company work. Add a clear photo, your trade or skill, and two or three lines about what you have done. - Local job and trade groups — Facebook and WhatsApp groups for your town or trade are where many real opportunities are shared first. You do not need all four on day one. Pick the one where your customers or employers actually are. A tailor or caterer may get more from WhatsApp Business and local groups; an IT support learner may need LinkedIn first. Add the others over time. WHAT MAKES A PROFILE TRUSTWORTHY - A real photo of you — face visible, plain background, neat clothing. No sunglasses, no filters. - Your real name, written the same way everywhere. - One honest sentence about what you do: 'I install and repair solar home systems in Hohoe.' - Proof: photos of finished work, a certificate, or a short quote from a happy customer. - A phone number or WhatsApp link that actually works. [Protect yourself] Never pay anyone who promises to 'verify' your profile or guarantee you a job for a fee. Real platforms like LinkedIn, WhatsApp Business and Google Business Profile are free to set up. Anyone asking for money to list you is likely a scammer. [Try this today] Write your one honest sentence — who you are and what you do — and save it in your notes. You will reuse it in every profile, CV and introduction from now on. PRACTICE QUESTIONS 1. Which of these is free to set up and puts your workshop on Google Maps? A) A paid business directory B) Google Business Profile C) A printed flyer D) A website you pay a developer for Answer: B — Google Business Profile is free and places your business on Google Maps and Search, so people nearby can find you. You only need a phone and your business details. 2. What is the most important quality of a professional profile photo? A) It was taken by a professional photographer B) It uses an attractive filter C) Your face is clearly visible and you look neat D) It shows you with expensive items Answer: C — Employers and customers want to see a real, trustworthy person. A clear, neat photo with a plain background builds more trust than any filter or expensive backdrop. ---------------------------------------- Auto & Motorbike Mechanic — Lesson 10: Write Your Goals and Plan for Obstacles 10 min read OBJECTIVE: Turn a wish into a written goal, review it weekly, and use if-then plans to handle the obstacles that usually stop you. A goal that stays in your head is a wish. A goal written down, with a date and a next step, is a plan. Research on how people actually change their behaviour keeps finding the same thing: people who write their goals down, check them regularly, and decide in advance what to do when things go wrong are far more likely to finish what they start. WRITE IT DOWN, THE PRACTICAL WAY - One goal at a time. 'Finish the solar course by 30 November' beats five vague wishes. - Make it checkable. You should be able to say 'done' or 'not done' — not 'I tried my best'. - Give it a date. A goal without a date quietly becomes 'someday'. - Write the very next small step. Not 'get a job' but 'message two hardware shops on Saturday morning'. - Keep it where you will see it — a notebook, a note on your phone, or paper on the wall. THE WEEKLY REVIEW — 15 MINUTES THAT CHANGE EVERYTHING Pick one fixed moment each week — Sunday evening works well for many people. Ask yourself three questions: What did I finish this week? What got in my way? What is my next step for the coming week? Write the answers down. This small habit catches problems while they are still small, and it reminds you that you are moving, even when progress feels slow. IF-THEN PLANS: DECIDE BEFORE THE OBSTACLE ARRIVES Most plans fail at the same predictable moments: the data bundle runs out, a friend invites you out on study night, rain cancels the job you planned. An if-then plan is a decision you make now, so a hard moment does not require willpower later. The format is simple: 'IF [obstacle happens], THEN I will [specific action].' - IF my data finishes, THEN I will study from my downloaded offline lessons instead. - IF it rains on the day I planned to visit shops, THEN I will call them instead and visit the next day. - IF I feel too tired to study at night, THEN I will do just 10 minutes — starting is the hard part. - IF a customer delays payment, THEN I will send one polite reminder after three days, not argue. [A note on visualisation] Imagining your goal can help — but picture the steps, not just the reward. Instead of only dreaming about the certificate on your wall, picture yourself opening the lesson, answering the quiz, and messaging the customer. Picturing the process prepares you; picturing only the prize can actually relax you into doing nothing. [Try this today] Write one goal with a date, then write two if-then plans for the obstacles most likely to stop you. Keep them somewhere you will see this week. PRACTICE QUESTIONS 1. What makes a goal 'checkable'? A) It is written in English B) You can clearly say whether it is done or not done C) Other people approve of it D) It is ambitious enough to impress people Answer: B — A checkable goal has a clear finish line: 'finish 8 lessons by Friday' can be marked done or not done. 'Do my best' cannot — and vague goals are easy to quietly abandon. 2. Your study night arrives and your data bundle has run out. What does a good if-then plan do? A) It forces you to buy more data immediately B) It tells you to skip studying until next week C) It gives you a decision you made in advance, like switching to your downloaded offline lessons D) It punishes you for not planning better Answer: C — An if-then plan removes the need for willpower in the moment: you decided earlier that IF data runs out, THEN you study offline. The decision is already made, so you just follow it. ---------------------------------------- Auto & Motorbike Mechanic — Lesson 11: Introduce Yourself in 30 Seconds 8 min read OBJECTIVE: Prepare and practise a short, confident self-introduction you can use with employers, customers and new contacts. Many capable people miss opportunities because they freeze when someone asks 'So, what do you do?' A self-introduction is a short, prepared answer — about 30 seconds — that you have practised until it feels natural. It is not showing off. It is simply making it easy for people to understand how you can help them. THE THREE-PART SCRIPT - Who you are: your name and your trade or skill. 'My name is Amina. I am a trained pharmacy assistant.' - What you can do: one or two concrete things, with proof if you have it. 'I have completed training in dispensing support and stock management, and I helped in a busy pharmacy for three months.' - What you are looking for: say it clearly. 'I am looking for a position in a pharmacy or clinic in this area.' or 'I take catering orders for events of up to 100 people.' Put together, it sounds like this: 'Good morning, my name is Kofi. I am a solar technician — I have finished certified training in home solar installation, and I have already installed systems for three families in this town. I am looking for more customers, and I also do repairs and maintenance. Here is my number.' Thirty seconds, and the listener knows exactly what you offer. MAKE IT YOURS - Adjust the ending for the listener: a customer hears what you sell; an employer hears what job you want; a contact hears how they can help you. - Practise out loud, not in your head — say it to a friend, a mirror, or your phone's voice recorder, five times. - Keep it honest. A small true claim beats a big exaggerated one that falls apart at the first question. - End with a way to reach you: your number, your WhatsApp, or where your shop is. [For shy learners] Feeling nervous is normal and does not mean you are bad at this. Preparation is the cure: a practised script means you never have to invent sentences while nervous. Start by using it in low-pressure moments — with a neighbour, then a shopkeeper — before the big interview or the important customer. [Try this today] Write your three-part introduction in your notes, then say it out loud three times. Use it once this week with a real person. PRACTICE QUESTIONS 1. What are the three parts of a good 30-second introduction? A) Your family background, your education, your hobbies B) Who you are, what you can do, what you are looking for C) Your salary expectation, your location, your age D) Your problems, your needs, your complaints Answer: B — The script answers the three questions every listener has: who is this person, what can they do for me, and what do they want? Keep it short, honest and practised. 2. What is the best way to prepare your introduction? A) Memorise a long speech about your whole life B) Wait for inspiration in the moment C) Practise a short script out loud several times before you need it D) Copy someone else's introduction word for word Answer: C — Saying it out loud — to a friend, mirror or voice recorder — is what makes it feel natural under pressure. A short, honest, practised script beats both improvisation and a long memorised speech. ---------------------------------------- Get the full app: https://miva-skillsnav.lovable.app
