Battery Light, what should I do? Options

[celicamike]

I've noticed recently that my battery light has been coming on periodically while I'm driving my '94 GT. It will come on for a second or two then go away, otherwise the car seems to run great. Have any of you experienced this, and more importantly, does anyone know what it means/how to fix it? Thanks.

The battery light WILL NOT come on because of the battery. That light is an indicator for your charging system. If that light is on, either one of two things is happening. Either the alternator quit putting out voltage to run the car and you're running off the battery (but the battery is still being charged, so you might not have starting issues) or.....the alternator quick putting out enough amperage to charge the battery, in which case you'll for sure run into starting issues once the battery gets down low enough on it's charge.

Take your car to Autozone, Advance Auto, pep boys, whomever. They'll do a test for free. My money is on the alternator being bad.
