Back up camera not working

[JLCHERITAGE]

We recently rewired our trailer plug and seem to have blown a fuse on the camera, but when we look at the fuse it is not blown. also now the jack levelers are not responding and the dash illumination panel lists door ajar when we go to start the motor home. In essence we have blown some sort of circuit in the motorhome, can it be possible that even though the fuses don't look blown that they shorted out and could cause all of these things.

we also are having a problem witht he pigtail for the trailer that we tow. the rv has a 6 pin and then it goes to a 7blade which hooks into a balded connection on the trailer, what started this issue was that we had no running lights on the trailer when we plugged in. HELP

we need to know what kinda moho, chassis, and year you have.
my sony back up cam system is on the same fuse as the coach aux heater blower.
fuses can be bad even though they look ok. sometimes you have to swap them or replace them to know for sure.
sometimes the coach has combination brake-turn-taillights and sometimes they are separate. most trailers use combination lights. if you cross a separate light system with a combination light system you usually need an adapter available at uhaul, cw, etc.
i cannot tell what your problem is from your description, but i gave you some ideas.

Hi,

Welcome to iRV2. As Dan posted, fuses can appear to be good and still be bad.

If you have a test light, use it to test for the presence of 12v on each side of the fuse. If 12v is present on both sides it's probably not the source of your problem.
