Why is my battery light on?

45

Asked by Nov 26, 2012 at 01:16 PM about the 2000 Ford Mustang GT

Question type: Maintenance & Repair

My battery light is on 90% of the time. It flickers at times but is on most all the time. I have had the battery and alternator checked and have all checked good. The battery is 5 yrs old but i have no starting issues with it at all. The car has a charging gauge and it is good. Is this an electrical glitch with the car or is there something wrong? it is annoying.

Usually when the battery light is on, it's the alternator, but you said it was checked out. Not sure what the issue is at this point. Keep your eye on the issue though.

WHEN A LIGHT FLICKERSC IT'S GOING ON & OFF QUICKLY. A SHORT WOULD {COULD} CAUSE A FLICKER, CHECK YOUR WIRING FOR BREAKS IN THE INSULATION.

Alternator interiors all made in China are crap. Even though they put out the amps. Diodes are lousy! Keep replacing under warranty. Until it runs correctly.

Also check all grounds!
