OK Folks
I think I have it. I checked the house outside outlet that I had been using for the past two years. I got no power at the outlet. Checked the circuit breakers and found no problem. Switched to the outlet at the front of the house and it has a GFI with a tiny indicator light. Plugged the bus into that one. I took readings on all batteries before and after hooking to shore power and they did not change until I switched house outlets. Checked voltage in the bus and reading 120 volts now.
All three batteries are up .5 volts from this morning but I am not sure if that is because ambient temperature rose a bit from this morning or because I ran the engine for 1/2 hour before lunch or if the converter is putting out power now. What should I do going forward? Any suggestions?
