Trailer wiring

[Timothy2001]

Realizing there are many different reasons the lights do not work on a trailer, are there any most likely causes on the RV side. Trailer has tested to be working fine. It’s a standard Chrysler female receptacle and I k it I am reaching but maybe it’s something simple. Maybe a separate fuse? Flashers and directional don coach work.

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.

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?

Power normlly comes off the rig's house battery for lights and appliances.When connected to shore power the converter should power the 12 volt system.
Common problem is dead trailer battery followed by blown fuse or tripped circuit breaker.
