Required tools and materials:
* Wrench set
* Screwdrivers (phillips and slotted)
* Wire terminals
* Insulation tape
* Multimeter
* Wires of the required caliber
* Cable ties
* Hand torch
Procedure:
1. Disconnect the battery: To do this, first disconnect the negative (ground) cable from the negative terminal of the battery, then the positive cable from the positive terminal.
2. Remove appropriate panels: Determine which panels need to be removed to gain access to the electrical wiring. Typically these are panels under the dashboard, under the hood and in the trunk. Remove the panels by unscrewing the screws or snapping the clips.
3. Identify faulty wiring: Using a multimeter, check the wires to find any faulty or damaged ones. Wires that do not conduct current or have high resistance may be faulty.
4. Disconnect the faulty wiring: Once you have identified the faulty wiring, disconnect it from the connectors or remove the bolts that hold it in place.
5. Install New Wiring: Route the new wiring along the same path as the old one. Connect the new wiring to the appropriate connectors or secure it with bolts.
6. Insulate connections: Use electrical tape to insulate all electrical connections to prevent short circuits.
7. Reinstall the panels: Reinstall the removed panels by tightening the screws or snapping the clips into place.
8. Connect the battery: First connect the positive cable to the positive terminal of the battery, then the negative cable to the negative terminal.
9. Check wiring: Start the engine and check that the electrical system is operating correctly.
Adviсe:
* Use wires of the same gauge as the old ones.
* Avoid sharp bends or pulling on wires.
* Connect the wires with quality terminals and tighten them tightly.
* Check electrical wiring regularly for damage or wear.
* If electrical problems still occur after replacing the wiring, please contact a professional auto electrician.
