I have replaced my alternator twice and my battery in the last 8 months but some of my idiot lights have started to barely glow when the 95 LSi is at idle after driving for awhile. The lights that glow are the battery symbol, power steering light, brake and bulb out lights;I'm thinking the alternator is gone again but when I had it replaced the second time (under warranty), the mechanic said the battery was the cause of the alternator failure so it was replaced and is only about 8 months old. I'm going to bring the car in for the mechanic to check both the alternator/ battery but wanted to be prepared for his answer. Anyone have a clue as to what may be the underlying problem?
