Possible reasons for turning off all electrics in the car:
1. Discharged battery:
* If the battery is severely discharged, it will not be able to provide electricity to the car.
2. Defective battery:
* Even if the battery is charged, it may be faulty and not provide sufficient current.
3. Connection problems:
* Faulty or loose connections between the battery, starter and other electrical components can cause an open circuit and loss of power.
4. Faulty generator:
* The generator is responsible for recharging the battery while the engine is running. If the alternator is faulty, it will not be able to compensate for the drain on the battery, causing the battery to die.
5. Damage or short circuit in wiring:
*Damaged or shorted wiring may cause a power outage or fire.
6. Blown fuse or relay:
* Fuses and relays protect electrical circuits from overloads. If a fuse or relay blows, it can cut off power to certain components.
7. Faulty ignition switch:
* The ignition switch is responsible for turning the electricity on and off in the car. If it is faulty, it may prevent power supply.
8. Car computer problems:
* The vehicle’s central computer can cut off power if it detects problems.
9. Disconnected ground terminal bolt on motor:
* The ground terminal bolt provides grounding for the electrical system. If it is loose or disconnected, it can cause electrical problems.
10. Electromagnetic pulse (EMP) interference:
*Strong electromagnetic pulses caused by lightning or military weapons can damage vehicle electronic components.
Diagnosis and correction:
* Check the battery charge using a tester.
* Inspect the battery terminals for corrosion or looseness.
* Check fuses and relays for blown ones.
* Check wiring for damage or short circuits.
* Check the ground terminal bolt on the motor.
*If all of the above are OK, take it to a qualified mechanic for further diagnosis.
