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.

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

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


Please give me enough troubles, uncertainty, problems, obstacles and STRESS so that I do not become arrogant, proud, and smug in my own abilities, and enough blessings and good times that I realize that someone else is in charge of my life.

Hey thanks for the info. I just looked at the main breaker Pannel and there is a breaker labeled "portable Appliances" I shut this breaker off. The others are:
Main, Air Conditioner, and General Purpose. I don't know what general purpose
stands for.

I would think 'General Purpose' would be outlets
Not sure what 'portable Appliances' would be?

Is converter still powered?

I don't know. I'll check in the A.M. Right now I'm running a power
strip on an extension cord.

I don't understand why (some of) your 115V outlets don't work. Maybe the breaker labelled portable outlets powers your outlets?

Why do you think your converter is shot? In any case, if you disconnect it, all your ac devices should work.

Just remember that you must have a charged 12-volt battery to power the breakaway switch just in case the trailer becomes disconnected from the TV.

I'm confused. If you want the 12 volt side to run with a bad converter, just disconnect the AC power to the converter. Get a battery charger and plug it into the 20 amp circuit on the pedestal.

Just remember that your air cond/heat and refrigerator has to have 12 volts to run the thermostats.

If no 12v or even low 12v, the fridge 'will' come on with shore power but when it hits the temp set and shuts off, it will NOT be able to turn back on without 12v running to it. Same with air cond/heat. Been there done that. [emoticon]

Did you shut off all the breakers to converter and turn them back on?
I found many times it will trip a breaker but not all the way. Visually at a glance you can't see it. And then check the volts on the converter. You could also just have a cooked battery.


We must be willing to get rid of the life we've planned,
so as to have the life that is waiting for us.
