I have a 96 GT auto. When I start my car for the first time in the day, everything is fine. But as it warms up and I drive it, the battery/charging meter goes down little by little until it is not charging anymore. I park the car and come back when it is cooled off and start the whole process over again.
The battery is only 1 year old, but the alternator has never been replaced. Any ideas? This is really strange to me. Seems the alternator should work or not work and no in between. Any help would be greatly appreciated.
