Greetings. I usually reside over at rec.motorcycles.dirt, but am looking for help on my Yukon XL.
Battery went dead a couple times over the course of a month and I figured it was time for a new battery. Dashboard ammeter indicates charging system is OK, the battery was at least 55 months or so into it's 72 month rated life.
In the process, I checked for anything that might be draining the battery down, and found a 1.3 amp drain with key off and out. Is this normal? I wouldn't think so, but I realize there are some circuits that must stay live.
I then put a light-em-up circuit tester in line with the neg terminal of the battery and the neg. cable, and proceeded to one by one pull every fuse in the panel under the hood and at the left end of the instrument panel. Light stayed on the whole time.
It's been suggested it could be a bad rectifier in the alternator, but I'd appreciate any pointers on whether this is an abnormal situation or not.
Suggestions on what to do next are appreciated.
