The reverse polarity fuses vary per type of converter. A stand alone style have the fuses in the DC end of converter. Converters that are integral to the power distribution panel are located in the 12 volt DC power distribution panel. Next to the 120 volt circuit breakers is a small plate held on by thumb screw. Fuses are behind plate.
Some AC units use 12 volts DC for control, so it is possible that is why it doesn't work.
Your power problem maybe that the batteries are not wired correctly. Two six volt batteries should be wired in series. The positive of one battery should be connected to negative of the other battery. The positive of second battery goes to DC panel through a fuse or 12 volt circuit breaker. The negative of the second battery should be connected to frame of trailer.
I would stay away from using 12 volt DC for the refer. Draws a lot of power at 12 volts.
Make of Tow vehicle GM products, you need to look in owner's manual on ho to connect charge circuit to trailer connector.
I've looked all over and I can't find a reverse polarity fuse.
I see lots of converters have a fuse right on the converter itself, mine doesn't. Mine is a 45 amp and looks rather out dated and small
I am thinking my converter doesnt even have a reverse polarity fuse.
I have about 8 blade fuses and about 4 or 5 110 breakers. Im sure one of those blade fuses is the converter, but they aren't labelled. I'll check for a 30amp fuse tomoorrow.
Thank you

I went and checked the voltage of the batteries (2 deep cycle new batteries).. They read 6.35 volts. I unplugged the 110 power and they still read 6.35 volts. i did this several times and it seems the voltage doesn't change wether they are plugged in or not?
Again, checked fuses/breakers and all good.
I checked the outlet that the converter plugs in, 118volts.
I checked the power leaving the converter and it was 6.35 volts (same as power at the batteries).

All my fuses are good.. BReakers aren't flipped.
I pulled the batteries out and measured the voltage from the pos/neg wires that go to the batteries--> 0.00 volts.. So I have nothing coming from my converter back to the batteries. Camper is plugged into a 110outlet and there is nothing on inside the camper except the display on the microwave.
Must be my converter...
I tested all the blade fuses with a voltmete and they are good. no breakers flipped, so unless there is a inline fuse I can't find (I traced all wires by feel from the converter to the fuse box/breaker boxes)..
