Battery indicator light help!
« on: August 10, 2013, 12:55:58 AM »
My 2002 ford mustang has had a problem with the battery light coming on and staying on then Going away then coming back, it's been going on for about 8 months now but hasn't given me any problems with starting and etc. the car does have a subwoofer and amp hooked up but never had any battery draining problems. The battery voltage was checked and everything was good. Any suggestions on how to fix this ?

Check the alternator output when the battery indicator is on.

I believe it should be roughly 14V.

I don't have any way of testing the output , what could it be a bad fuse or something? I've driven the car tops for 2 hours straight and haven't gotten a problem in the last 8 months with the light being on .

Battery fully charged? Alternator only working half the time? So it drains battery and then charges it.

As I said, have the output of the alternator checked.

Try and get the alt tested while its still in the car. I personally have had bad luck with taking in an alt and the people saying its still good when it wasn't.

In case you didn't already know, auto zone and O'Reilly offer free alternator testing. They test both the battery and the alternator. Of do that, also double check your grounds and alternator connections to start off with.

For AutoZone to test your alternator they want it out of the car... It is worlds easier to hook up a volt meter while it's in the car and see what the output of it is.
