7 pin electrical issue

[Kies277]

I have a short on the 7 pin connector wiring. I took apart the junction box and disconnected the 7 pin connector and found that the connector is fine, it is in the trailer wiring (2015 Crossroads Sunset Trail 5th wheel). I have continuity between ground and the brake lights, ground and running lights, ground and trailer brakes.

After checking all the working I could, I found no damage. I suspected they may be pinched in the nose cone so I cut the running light wire in the trunk where the batteries are to isolate the section of wire between the junction box and there and now I'm baffled. I got continuity between both sides of the cut wire. Also, both sides of the cut wire have continuity with ground.

All the wires in the junction box are disconnected. Anyone have any ideas?

Check your breakaway cable/box. It may be shorted or pulled and connects everything you are talking about. Also your lights are grounded to the frame so it probably would show continuity to ground.
