12 Volts to trailer conector fuse?

I have 12 volt LED light panels inside my 20' enclosed trailer and in doing some testing, I blew a fuse. I checked under the MH hood and under the MH dash panel and they all test good. Any idea where it could be? I also have AC lights and a 12V wall wart wired in the trailer so I can use the 12 volt lights on shore or generator power and both the AC and DC work on AC. All the trailer running/ turn and stop lights still work.

Did you check to see if there is power at the plug coming out of the MH. Maybe the fuse is blown somewhere in the trailer. If you did all this just figure this my two cents worth. Jim

Just checked trailer connector again. Flashers, turn, running and 12 volts to trailer connector good, so it is in the trailer. Thx for the reminder. I think the fuse is in the break-away box or near to it.

Got it. It was a loose or corroded wire or connector right at the connector that plugs into the MH 7 pin connector. It wasn't anything the would have prevented me from motoring down the road.

Feels good to resolve the problem w/o spending big bucks, no?

Yeah, it was like doing something I shouldn't have done, like feeding 12 Volts where there was already 12 volts. Although I do it all the time, for some reason, didn't like it this time. I think it was from feeding an outdoor ramp light from a wall wart.
