I own a 1995 3.4L DOHC V.6 Lumina which my son drives. He had problems a couple of times this week with the battery being dead. My suspicion was either the battery was not sufficiently charged after being jumped - he jumped it once at night and drove it around with lights on - or the alternator is not working.

I've been out of town, and I looked at it today. I can jump the batteryeasy enough, but the VOLTS, AIR BAG, ANTI LOCK BRAKE, and SERVICE ENGINGE SOONlights are either on or intermittently on and off while it is being driven.

Is this an alternator problem?I just replaced the alternator and battery within the last 9 months or so.

Thanks for any advice ...
