Thanks Stan.

That power supply was labeled as 12 VDC output (just a wall wart). I was a bit surprised to measure 13.4. The reminder and caution on using it is appreciated. It isn’t the one that was being used for operation, that one was flaking out so I had to swap a different one in. May be time for a real power supply.?
I’ll get inside and do the additional diagnostics.
