Battery warning light

I have a 1999 Mazda Protege DX with 108,000 miles. My battery warning light came on two weeks ago. I went to Autozone to get it checked out and they said everything was fine. So, I ignored the light. Well, my car died the following week. I got a friend to change out the alternator to a new one and the light disappeared. The week after, the light came on and the car died. I had the battery checked and they said it was dead. I replaced the battery and my car started working again. However, my battery warning light is still on. I went to Autozone to get it checked just in case the alternator went bad on me. They said that the alternator and battery were fine. I looked at the belts and everything looks fine. Am I missing something? Do I need to reset the light somehow or will it disappear after a while? I don't want to ignore the light and then have the car die on me again.

Don't ignore it. You'll get burned. Get your money back for the faulty alternater and get a good one. Worldwide, bosch, USA are decent alternaters. Autozone. Is quality challenged. IMHO.

Sounds to me that the PCM is not controlling the field winding generation. Instead of dropping the resistances to increase the voltage-its increasing it to lower the voltage. Low voltage is equal to low current output from the alternator.

The vehicle is not meeting its electrical demands.
