Auto Electrical Repair

If you own a car, some knowledge of how to repair auto electrical problems Auto Electrical Repairwill be beneficial. Below are some common electrical issues with cars and how to resolve them.

Fixing Electrical Headlight Shortages

Required Tools and Materials

Electric headlight
Volt / ohm meter
Wire crimping tool
Wire brush (small)
Wire cutters
Headlight bulbs (must be of model and year of the car)
Service manual
Wire connectors (multiple gauges)

Step 1

Check in the car service manual to find out the position and color of the wire. Look out for signs of corrosion; this may cause a short. When you see the broken wire, assess its gauge. You should also check if it is a ground or hot wire.

Step 2

Utilize the volt / ohm meter to look for an open circuit. This will register on the meter. Before you repair auto electrical problems, make an assessment of the severity of the damage.

Step 3

Slice the wire on its ends. Throw away the broken wire. Select a wire connector that is fit for wire. Set the wire on the connector’s endpoints. Get the wire crimpers and tuck the two ends. This process should be repeated for other broken wires in the circuit.

Step 4

Inspect the ground wire with the volt / ohm meter (usually this wire is black). The wire is damaged if there is no battery reading. Repeat the process earlier to find and fix damaged ground wires.

Step 5

To repair auto electrical problems involving headlights, you need to find the fuse box and headlight fuse. For the fuse, you need to set the black probe on the ground part. The red probe should be on the hot side. If the reading is 12 volts, it’s all right. If not, the fuse is defective. Replace it.

Step 6

Test the bulbs by turning on the headlights. Try both in high beam and normal. Replace the bulb if either one isn’t working. If neither one is working, inspect the light socket. If there’s corrosion, clean it with a wire brush. Try the light bulbs again.

Repairing and Replacing Fuses and Circuit Breakers

A simple rule to keep in mind is this: all electrical parts in the car need voltage to work. For you to be able to repair auto electrical problems, you need the voltmeter or 12 v indicator light.

Find the component that isn’t working. Find its power source and connect it to the voltage source. If there’s no voltage reading, the problem is either the fuse or the circuit breaker.

Note: you can replace the fuse and the car might start. However you still need to check the circuit breaker. If the circuit breaker is damaged, the auto will malfunction again. To test the circuit breaker, bypass it by using a jumper wire. If the other components work, then the circuit breaker needs to be replaced.

Sometimes the cost of maintaining a car becomes prohibitive because people don’t know how to repair auto electrical problems. Why pay a mechanic to do the inspection when you can do it yourself?
