Travel trailers in most cases do not have battery switch.
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
On my previous trailer the reverse polarity fuses were in a bundle taped up under the tongue. I have never seen a trailer that did not have them somewhere, I assure they are there somewhere. The way to be sure is to check the voltage right at the converter output. If they’re external to the converter then you should have voltage there and not at the batteries. If you don’t have voltage right at the converter then the fuses could be in the converter.
I had 0.00 volts at the converter on the DC end. So can I assume they are in the converter itself? And can I open it up to replace them?
The guy I bought it from JUST replaced the batteries before I bought it so I'm guessing theres a good chance he hooked them up wrong and blew the fuses.
