Stages of repairing electrical wiring in a car:
1. Fault diagnosis
* Identify symptoms of malfunction (for example, lighting problems, engine malfunctions, or failure of electronic components).
* Check fuses and relays for damage.
* Use a multimeter or scanner to check voltage, resistance and continuity.
2. Identifying and repairing damaged wires
* Identify damaged or broken wires by signs such as melted insulation, exposed wires or corrosion.
* Cut off the damaged section of the wire and solder or crimp a new wire.
* Insulate the connection with heat shrink tubing or tape.
3. Elimination of corrosion
* Clean the battery terminals, connector contacts and grounding points from corrosion.
* Apply anti-corrosion spray or Vaseline.
4. Replacement of faulty components
* If necessary, replace faulty components such as sensors, switches or control modules.
* Ensure a good electrical connection and secure the component.
5. Check and reinstall
* Check the repaired wiring using a multimeter or scanner.
* Reinstall all components and make sure they are working properly.
Common car wiring faults:
*Blown fuses
* Loose connections
* Damaged wires
*Corrosion
* Faulty sensors or switches
