Lights

[chamblyn]

Hi all. We have a 2010 Jayco Jayflight 22 FB. Just returned from short trip & noticed the running lights on trailer were not working. The turn signals & stop lights are working on trailer. Any help is appreciated!

Start with the truck and work backwards. If you have voltage at the 7-pin socket, then the problems in the trailer wiring.

Could they be on a separate fuse?

I had this problem with an old trailer. I never completely figured out the root cause, but I always had to replace a fuse in the truck. I'm sure it was a short somewhere in the trailer wiring because the problem stopped when I sold that trailer, but I never did find it. I think I had to replace that fuse 3 or 4 times over a 2 year period.

Not sure how they wired the OP rig, but since it's a 2010, there's a possibility the ground wire for the at circuit is an issue. On my rig, a whole bunch of different grounds come back to a common point on the frame. If one of those connections are corroded (a common problem here on older rigs), that would cause the circuit to stop working.

Maybe a quick slide under the rig and trace some ground connections should be considered.
