Hi Everyone, My girlfriend bought a 1998 Coleman Cheyenne a couple weeks ago. I’m helping her test everything, I found that when it’s connected to the TV, none of the trailer lights work - no brake, no running lights, no turn signals. I’ve checked the voltages on the TV 7-wire pins and they all work. When the PUP is open and connected to 120V, the forward rocker switch does turn on all of the exterior lights (running & brake), so I know they work. I’m inclined to assume the PUP connector has failed but I’m wondering if there is a switch somewhere that needs to be flipped in order determine whether the lights respond to the TV wiring or the 120V supply?? If it should just work, what I’d like to know is where the other end of the 12V wire bundle from the 7-wire connector comes out so a I can test each individual wire run from the 7-wire plug. Thank you for any and all help!
