You may want to try disconnecting the battery now and see if the system returns to normal operation.

Thanks Jim, I'll give that a try.
Had to but it back together so I could get the mandatory annual NYS inspection. While driving there it set a Code 09 on the AC, low freon, so looks like I have a slow leak. Last charged it 2 years ago. No heat and no A/C.
Looks like I've got a couple winter projects.
