Replacing electrics in a car
Required tools and materials:
* Screwdriver set
* Wrench set
*Multi-function tester
* Electrical tape
* New electrical components (if necessary)
* Grease for electrical contacts
* Protective gloves
* Safety glasses
Precautions:
* Disconnect the battery before starting work.
* Wear protective gloves and glasses when working with electrical equipment.
* Never work on electrical equipment while the engine is running.
* Use the right tools for the task.
*Follow all maintenance recommendations found in your vehicle’s owner’s manual.
Instructions:
1. Disconnecting the battery
* Wear protective gloves.
*Locate the negative terminal of the battery (usually marked with a “-“).
* Loosen the union nut with a wrench and remove the terminal from the battery.
* Repeat this for the positive terminal (usually marked with a “+”).
2. Fault diagnosis
* Use a multi-function tester to test electrical components and circuits.
* Determine the source of the problem (fuses, relays, wiring, etc.).
3. Replacement of faulty components
* Remove faulty components by removing wires or screws.
* Install new components in reverse order.
* Tighten all connections.
4. Wiring repair
* Trim damaged sections of wire.
* Connect new wires using connectors or a soldering iron.
* Insulate connections with electrical tape.
*Replace the protective insulation around the wires as needed.
5. Lubrication of electrical contacts
* Apply a small amount of electrical contact lubricant to all terminals and connections.
* This will prevent corrosion and improve electrical conductivity.
6. Battery connection
* Connect the positive terminal to the battery first and then tighten the nut.
* Repeat this for the negative terminal.
7. Check
* Turn on the ignition and check if the electrical component is working properly.
* Make sure there are no current leaks or other signs of malfunction.
Adviсe:
*If you are unsure of your abilities, it is best to contact a qualified mechanic.
* Record all changes made to the electrical system for future reference.
* Check your vehicle’s electrical system regularly to prevent problems.
*Keep your vehicle’s owner’s manual for reference on specific procedures and electrical system specifications.
