i have a 1995 chevy cavalier and i just replaced the battery (so it's brand new), and had a new alternator put in when my car died on the side of the road while driving. The car drove around fine for the afternoon, and now my battery light came back on and won't go off. I was just wondering what could be causing this. Could it be my voltage regulator or my wiring harness connecting to the alternator itself, or something completly different... any help would be great. Thanks!!!!!!!!

Make sure the fan belt is tight, try this test for the alternator.... with the car running remove the positive battery terminal, if the car dies the alternator is bad, if the car stays running the alternator is good. Even though you got a new alternator is could have been a rebuild and a bad one.

The vehicle is in a relearn mode. The light will go off soon. The same thing happened on my 2001 Montana. Normally the battery will not cause the battery light to come on. This would be the alternator causing the light to come on. If it was properly diagnosed, and the alternator had failed, you are in relearn mode, and it will be ok. If it was not properly diagnosed, and the alternator was not the problem, it may be the wiring or a fuse. You can have the charging system checked at Autozone, but make sure they also check for power at the 12v on the back of the alternator to make sure the alternator is getting power.

I would go with the Dodge Man on this one. The first thing I would fault is the alternator. I had a 69 Mustang that went through 8 alternators in a matter of 3 months. Go get your charging system checked again. Although the alternator may function OK at idle, it may not charge properly under load.

Stacey: Your battery may not be charging properly when your driving the car. Go back to the place that sold you the battery and have them check the battery and charging system again for free. They may never have done an alternator charging test to make sure the alternator is charging the battery.
Here's a good online video on proper "jump starting" in case you get stuck some where and need a jump start. Bring your cell phone.

First, check the "Alt" (alternator) fuse under the dash.
Hell, check ALL the fuses.
If you have a volt meter, check the battery voltage with the engine running.
It should be over 13 volts DC.
If the simple checks don't find anything, take it to Autozone, Pep boys, or any good auto parts store for a free checkup on the charging system.

what you need to do is take it back to where you bought the battery at,they should have tested the charging system really good when they put the battery in it,,they probably didn't though,and this could be the alternator not charging the way it should be,even though its new doesn't always guarantee thatt its good,very often people by parts tha are new or re-built and they don't work right,take it back to them and have them check all of this,I'm sure they,ll find it,good luck with it.

this is the alternator not charging. If the sunshine isn't totally vibrant or glints it would desire to be the slip ring brushes, which you will replace for lots much less money than an entire new alternator.

All the items you listed could be at fault.
But don't forget to check the belt, it may not be tensioned right.
