Hi, I´m repairing the 92 Cavalier 2.8 of my wife, great car.

I have a constant battery red light in my board.

My mechanic fixed de diode board and the regulator. I apply the guarantee of my battery and replaced it.1 week ago. But leave me again in the highway.

And replaced again the Regulator by an original one. Half an hour later with the stereo and the air flow on.

But the battery does not keeps the charge. Any ideas?

Greetings

 

it sounds like your altinater (yes i know i didnt spell it right) take the alt to an advance auto parts/autozone and they can check if the alt is bad..
