Why does the car light stay on and can't be turned off?
1 Answers
If the light stays on, it means the battery is discharging. The light goes off after starting the engine because the alternator is charging the battery, putting it in a charging state. If the charging warning light remains on after starting the engine, it indicates that the car's charging system is not functioning properly and there is a fault in the charging system. Alternatively, if the charging warning light comes on while driving, it means the alternator is charging the battery, and the car is running on battery power.
