I have a 2015 Montana 3100RL fifth wheel. It’s began to blow the reverse battery protection fuses. I checked the battery connection and the white wire that is grounded to the frame is attached to the negative terminal on the battery. The black wire that goes to a terminal block is attached to the positive terminal of the battery. The battery is new and has a full charge. The 12 volt system seems to be working ok, lighting, carbon monoxide system, hydraulic jacks and etc.. Any suggestions what to check would be appreciated.

Seems pretty straightforward to me. If everything is as you say, sounds like the converter is bad.

Make and model of converter?
How often is reverse polarity fuses blowing?
Dis connect 12-volt wires from converter, see if the fuses blow. Possible issue is in DC distribution panel.
