Voltage Toy Hauler Owners (I need a favor)

[arlan in arizona]

I was wondering if anybody that has a Voltage Toy Hauler and access to the unit would do me a favor. I need to know if your refrigerator electric plug is a GFI plug on non GFI.

The reason I am asking this is I have a Voltage 3905 and had solar, extra batteries and an inverter installed at the dealer. My refrigerator is on a non GFI plug and the inverter operate all non GFI plug. So, when the coach in plugged into shore power with the refrigerator in AU mode when I disconnect it senses AC voltage from the inverter and starts drawing off of the batteries. Every plug on the exterior (or anywhere near the exterior) of the coach is GFI. Except my Refrigerator.

I know I could just remember to set the refrigerator to manual but it is the if the coach is wired wrong I want it fixed. My voltage is in for warranty work right now but I am banging my head against the wall to get any help from said dealer.

I guess the way to check it would be to turn on the refrigerator set it to AC and turn off the GFI circuit breaker. If refrigerator switches over to LP then mine is wrong.

I know. It's a favor. I hate asking favors but I don't know where else to turn.

Thanks
