You probably already thought of this, but the obvious first thing is to check the battery. It is possible it could have a bad weak cell and still start the car. That sometimes relates to strange displays, loss of program, etc. After replacement, some electronics might need to be reset.
Please post what you find out. Good luck.

If the battery circuit opens for some reason the VR will cause the alternator voltage to go into orbit, skyhigh. Check/clean/burnish the posts/connections.
