Unreal.

Hopefully this is the diagram you're using.

Everything on the rig works, nothing on the trailer works. No power at all to harness 30 amp breaker/fuse is good. Trying to track down power source now, wiring diagram not proving to be helpful.

What works and doesn't work?
Are you talking stop, turn and tailights or interior system?
if you are talking running lights, Have "you" tested from the trailer connector by jumpering between contacts in connector?
Does your tow vehicle have amber turn signals? Does trailer have red turn signals?
if yes, look for a tailight converter.
Have you tested rig?

Have you cleaned the contacts on both the plug and receptacle?

and the ground wire is a real trouble maker , before you jump into cutting etc ,pull the ground wire off the frame clean reinstall. the ground can cause alot of strange things to happen.

My coach has separate fuses for the trailer. Mine are located in one of the basement compartments near the rear end of the coach.

HAS a trailer every been hooked up the the Rv.

Asking about the trailer only, which lights are not working? Are you talking the exterior running lights? How about the brake stop and turn signal lights on the trailer, do they all work?
