Car electrical repair
Diagnosis of the problem
1. Identify the symptoms of an electrical fault, such as:
* Malfunction of appliances or lights
* Problems starting or charging
*Combustion noise or smell
2. Visually inspect the electrical system for the presence of:
* Cracks, wear or corrosion of wires and connections
* Damaged relays, fuses or other electrical components
Troubleshooting
1. Replacing fuses: Check the fuses for blown or damaged fuses. Replace blown fuses with fuses of similar rating.
2. Battery Test: Use a multimeter to check the battery voltage. Charge or replace the dead battery.
3. Checking the generator: Start the engine and measure the voltage at the generator. It should be about 14 volts. If the voltage is low or unstable, replace or repair the generator.
4. Starter Check: Check that the starter is receiving power and turns on when you turn the ignition key. If the starter does not turn on, replace or repair it.
5. Lighting Check: Check the bulbs and fuses associated with faulty lighting. Replace burned out light bulbs and blown fuses.
6. Wiring check: Use a multimeter to check the continuity of the wires. Replace or repair damaged wires.
7. Check Relays and Modules: Check the relays and modules associated with the faulty component for power and signs of failure. Replace or repair faulty relays or modules.
Security measures
* Disconnect the negative terminal of the battery before starting work.
