can I seperate the 12 volt from the 110 system?

Yeah. Fulltimer with a problem.
I am pretty sure my converter is shot. My question is can I
Seperate the 12 volt system from the 110 system?
I can use lamps for lighting. But would really like to use the wall
Outlets to plug stuff in. I use a heater buddy for heat.
I think the 110 side is ok but there's a problem with the 12 volt
side. The trailer is a 79 Terry 24 foot. No serious electronics
In this model. Can I? Huh? Pretty please?
I did put a new heavy duty battery on. But still get loud hum and
Clicking from the converter.

    Or connect a standard car batter charger to the RV battery.

    120V AC and 12V DC systems ARE already separate.

    Turn the 120V AC Circuit Breaker for converter OFF or unplug it if not wired to a CB) and 12V DC system is strictly on battery supply...which will then need an alternative source of charging

    Replace Converter and then you have best of both worlds
    Working Charger for battery/DC System Power source when connected to 120V AC and
    Battery to supply DC System when NOT connected to 120V AC

    120V AC System:
    A/C Unit, microwave, TV, Fridge/Water Heater electric elements, wall outlets, Converter

    12V DC System:
    A/C Unit T-stat---Furnace, water pump, Lights, Fridge/Water heater Propane controls, fans, etc
