I have been trying to find the source of my problem with the 12 volt power in my 2021 3761FL for a couple of months now. When the unit is connected to shore power, everything works. When I disconnect shore power, nothing works. I have troubleshooted the following items below:

1) Inverter is good when plugged in, starter wire is getting 12 volts
2) Converter is working properly and even talked with a tech at Progressive Dynamics to confirm I was checking all correctly
3) Battery is good and properly charged
3) The power key in the wet bay is in the right position and cannot be removed
4) Battery shut off in the front compartment is "ON"

When I disconnect shore power, I have no 12volt anywhere in the coach and the inverter is not running and powering the refrigerator.

What am I missing?
