The alternator still charges the battery justfine, though. Tomorrow afternoon's first troubleshooting step will be to remove the connection on the alternator.
The alternator will still charge with a bad diode, but it won't do it as well as it should. However, an unremoved auxiliary fuse for the wretched Chrysler ACC is an even more likely suspect. I'd start there first, actually. These things are notorious for freezing up and drawing current 24x7. To top it all off, repair is expensive! -- Jim
