Hi all please help.. I baught my car 4 years ago and 1 month in the alternator bearing went so I had a garage replace. When I got back the battery light was on and had to have a new one replaced again. 1 year later the alternator was faulty, over charging so replaced again. Since then sometime very rarely battery light will be on when started but soon as turn off and on its gone. I have noticed over last year my headlights go dim when take foot off gas but brighten when press gas again and my dash light in left corner sometimes on or off... so put GM tech2win on and it came up with p068a and some other pic attached. But is overcharging when high speed. Battery been in since I got 4 years ago but power test shows cranking fine but low charge.
