Electrical/Converter inquiry

I have a 2015 Open Range Journeyer and this past weekend, I discovered the refrigerator, stereo, carbon detector or AC were not working. I am plug into a 50 amp and have a battery hooked up. I discovered my WFCO converter popped both 35 fuses but nothing else was tripped. I unhooked the battery and replaced the fuses. I got the AC working but not the fridge or stereo. Vent fans were also dragging. At the end of the trip, I hooked the battery back up and immediately both fuses popped on the converter. Instead of dragging the RV in for service, would replacing the converter solve the issues are could it be more? Any help is greatly appreciated

    Typically large amp fuses on a converter are 'Reverse Polarity' fuses to protect from battery being connected backwards....cables reversed.

    W/O Battery connected ALL of your DC System should have been functioning when pulled into AC Shore Power as converter should have been supplying the DC System

    W/O Battery connected converter with 120V AC input should have at minimum 13.2V DC output.....any less and converter is/has failed.

    Blowing those fuses........battery cables are backwards OR....if cables have not been removed/re-installed then battery is shorted internally (check specific gravity of each cell)
