AUTO REPAIR GUIDE

A defective fuel  gauge will give inaccurate readings and they can make driving frustrating. If the readings on the fuel gauge is always the same, always empty or full, gives wrong readings all the time then you are dealing with a faulty fuel gauge  The possible causes includes defective voltage regulator bad gauge bad wiring between gauge and sending unit faulty sending unit It is most likely a defective voltage regulator if the temperature and oil pressure gauges are also affected but if only the fuel gauge has issues then the problem is rooted in the gauge itself, the sending unit or the wiring

The electrical system of a car is a closed circuit with an independent power source 'the battery' Apart from the main charging, starting and ignition circuits, there are other circuits that power lights, electric motors, the sensors and gauges of electrical instruments, heating elements, magnetically operated locks, the radio and so on All Circuits are opened and closed either by switches or by relays - remote switches operated by electromagnets Circuits have components connected to them,  and to operate these components they require voltage so, no voltage no function' which makes the first order of business when diagnosing electrical problems is to check the circuit's load point(bulb, wiper motor, any element the circuit is suppose to power) for the presence of voltage. If you find no voltage at the load point, you just uncovered the first clue about what a problem might be. Then you can check the fuse, fuse link, circuit breaker and also the relay supplying volt...

Both headlights are not working--  This is usually caused by lack of voltage supply to the headlights due to wiring fault bad headlight relay/fuse/headlight switch/dimmer switch/module To know the exact cause of the headlight problem, retrieve your owners manual and locate the main fuse for the headlight circuit. If it'd blown, replace fuse with a new one but if it blows again like almost immediately, then there is problem in the headlight circuit that will have to be diagnosed and repaired before headlights will function again. But if the fuse does not blow and your headlights are still nor functioning, this is likely because there is no power at the fuse which would indicate a fault in the wiring either in the fuse block or between the fuse block and the battery If there is voltage in the fuse, then it's time to inspect the headlight relay. You do this by pulling the relay out and shaking it. If something rattles inside the relay it means it's faulty, time to ge...

You get home, park your car, do some stuffs and go to bed only to wake up the next day and discover your battery is dead. Here are some of the likely culprit PARASITIC DRAIN This means there is something drawing power from your battery while it's parked. If you have your stereo presets, security alarms or clocks running after the engine is off, it can drain your battery. This type of drain is known as parasitic drain. Parasitic drains below 75 milliamps are considered normal, but any parasitic drain over 75 milliamps will drain the battery quickly. The most common causes of parasitic drain are under hood lights, trunk lights, headlights or glove box lights that do not turn off when the door is closed. Relay switches that are stuck in the “on” position can also cause a battery to drain FAULTY CHARGING SYSTEM A faulty or unreliable charging system can also drain the battery while the car is running. When an alternator is not pushing out enough voltage, which should be betwee...

An headlight that won't turn off isn't an issue that can simply be ignored even when the car is not in use. Emergency measures to take so as to safeguard your battery includes i. Disconnect the battery ii. Remove head light fuse iii. Remove head light relay Head lights systems are not overly complicated, there will be times when taking your car to a professional will be your only option but before that here are some ways you can try to fix things your self If the problem with your head light is a result of bad head light relay, the solution lies in replacing the relay. This is quite easy to check as multiple circuit may use the same kind of relay in their connections. Look for an identical relay from a different circuit and swap with your head light relay, if it works it means problem solved. Your relay needs replacing but if it's a switch malfunction, the diagnosis is a bit more complicated, this is when you should definitely consult a professional

PROBLEM: This can be rather frustrating, you just bought a new car battery and whoops, it's dead Well, i have got good news for you. It's not your car battery that needs fixing, the  problem is your alternator SOLUTION: Replace the alternator, though often times all one has to do is replace the connections HOW TO REPLACE ALTERNATOR i. Disconnect the positive cable. This cable should be red ii. Locate the alternator on your vehicle iii. Using a serpentine belt tool, loosen the belt and move it off the pulley of the alternator iv.  Put back the bolt that holds the alternator in place. These bolts depends on the make and model of your car, they should not be less than two and a maximum of four v. Use a socket and ratchet to loosen and remove the bolt vi. Pull out the alternator, then unplug and remove the nut for any electrical connections vii. Remove the alternator and take it to a spare parts dealer or house to get a new one or rebuilt one viii. Insp...
