I recently came into possession of a 2003 XG350 w/194K miles. When I got it, the battery was dead as a doornail: less than 9V with the car off and didn’t take a charge. I barely got it running with a jumper box, but the battery still showed less than 10V and the battery light was on.
Bought a new battery and alternator. Talk about a bitch of a job to change that friggin’ alternator, but I guess that’s a topic for another thread/discussion...
Anyway... Went for a drive, but after a few miles the battery light came on again. It goes out when revs are above 3000 either while driving or standing still. Light on and the car idling, multimeter only shows 12.6V from the terminals, so clearly it’s not charging.
So... Any suggestions as to the next course of action? Battery terminals are secure, battery cable to the back of the alternator is secure, connector to the alternator is secure and serpentine belt is tight. That should all be it, right? Even checked the fuse next to the positive terminal of the battery and at least it looks good.
What else to check? Kinda getting stumped here, so any and all suggestions are appreciated. Even any simple things you could think of I might be missing. Just don’t really want to kill the new battery.
