Hi Ron,

Yes, I would say they are related.  From the owner's manual section on troubleshooting transmit problems:

"... low voltage may cause an erroneous temperature reading..."

The ERR 12V message also indicates low voltage. 

I think you're on the right track checking the circuit breaker lugs, etc., but be sure to check the obvious things first, like measuring the supply voltage, making sure the connections on the power cord are tight, etc.
