hey thanks! dealer is putting in a new alternator tomorrow, no charge as vehicle is gm certified, said they had another 00 Lesabre on the lot, tested it, was pulling a constant 15v, mine was fluctuating between 12.7 and 15...I hope this does the trick.
Pardon my ignorance, which grounds should I be checking? Battery, all light sockets? anything around the fusebox? I know a lot of useless things about cars, but don't know much about working on them.
Thanks
