2002 Chevy Trailblazer 6 cyl Two Wheel Drive Automatic 130000 miles
I seem to have an electrical drain. I have replaced the batter and the alternator checks out fine. If I jump the car, I can drive all day. It can sit for quite a while and upon return, starts normally with no noticable delay. If I leave the car overnight, the battery will completely drain to the point that it won't click and no accessories will come on. My previous battery was 4 months old and I just got a new battery a week ago. I would think the alternator is bad but wouldn't the car eventually die after driving for a while if the alternator were out?
All electronics seem to work normally. I have no burned fuses, (check them all) and nothing appears to be on when I turn off the car. I've even snuck into the garage late at night to see if anything is lit but the only light I see is the intermittent flashing of the security system LED on the radio pod.
Help. This is driving me crazy and I'm not to happy about letting the dealership blindly poke around for $85 an hour.
