Possible reasons why the electrics in the car do not work:
1. Defective battery:
* Check the terminals for corrosion or looseness.
* Measure the battery voltage with a multimeter; it should be above 12.6 volts.
* Replace the battery if it does not hold a charge.
2. Damaged generator:
* Check the alternator drive belt for wear or breakage.
* Measure the voltage at the generator terminals; it should be around 13.5-14.5 volts with the engine running.
* Replace the alternator if it does not produce current.
3. Damaged starter:
* Try starting the engine using ignition cables from another car.
* If the engine does not start, check the starter and replace it if necessary.
4. Blown fuses or relays:
*Check the fuse panel for blown fuses.
* Replace blown fuses with fuses of the same amperage rating.
* Check the relay for damage or corrosion.
5. Wire break:
* Visually inspect the wiring for damage such as chafing or tears.
* Check connectors for corrosion or looseness.
6. Ignition switch malfunction:
* Try turning the ignition key several times.
* If the key is difficult to turn or does not turn at all, the ignition switch may be faulty.
7. Problems with “mass”:
* Check body ground points for corrosion or looseness.
* Clean and tighten grounding points.
Troubleshooting tips:
*Start by checking your battery. If it is low or defective, charge or replace it.
*Then test the generator to make sure it is producing current.
* Inspect wiring for damage and replace damaged areas.
* Check fuses and relays and replace any blown or defective ones.
*If the problem persists, seek professional help from an auto mechanic.
