If your car battery light keeps coming on despite having a good battery, belt, and alternator, it could be due to a faulty voltage regulator, which controls the voltage output from the alternator. Additionally, loose or corroded connections in the battery or charging system can cause the light to activate. It's also possible that there is a problem with the car's onboard computer or wiring issues, which may require a diagnostic check to identify.
it could mean that you have a loose battery cable that needs to be tightened
Have the charging system checked. Possibly loose or corroded wiring, a loose alternator belt, or a bad alternator.
Possibly a bad alternator. The Alternator charges the battery when the vehicle is running. If the battery is not being charged this could cause the vehicle not to start.
battery hooked up backward, wires crossed somewhere or it could be the solenoid.
It could be the voltage regulator.
No, the battery light is coming on because there is a problem with the charging system. Most likely the alternator is failing. Most auto parts stores will check your system for free.
Alternator, silenoid, battery cables. After you have checked those 3, try a new battery if its more than 3 years old.
The battery "starts" the car...after that the alternator keeps the battery charged. They work together in other words.
It could be two things. As you know, the alternator charges the battery so it will not drain. If the alternator is not working properly to charge the battery, the battery will continuously drain. Have the alternator tested at your local Auto Parts store (NAPA or Advance Auto) If it is good, have the battery checked.
my battery light keeps coming on why is that, ive replace the battery and it still happening please help?
The battery will run down and he engine will stop. You will not be able to start the engine. The alternator keeps the battery fully charged.
