7 pin issue

[Chris1304]

Have an issue when I plug my trailer into tow vehicle my right brake light stays on and no other lights work.. I've tested the trailer and everything checks out ok . So I have moved on to tow vehicle . Started testing pins and I have power to top 4 pins for some unknown reason ? Any thoughts

Possible internal corrosion in plug? How old is it, got a boat you put in the water a lot?

Year old and have pulled plug apart and no corrosion noted.. Showing 13.6 volts on top 4 pins when only one should have power without brake pressed or blinker on.

I am sure you have a diagram, if not here is one.

Sounds like something is shorted somewhere. Either in the plug or back towards the engine bay.

I'm getting ready to trace all wires back

Thanks for the diagram !

Ended up just cutting out the whole controller and ordered a new one.

Not sure if you found your problem but I had some issues similar and it ended up being a controller under the dash.

New controller on order from Curt. When I pulled the old one out it was warped from heat and cracked so I'm assuming this should correct the issue I'm having. Thanks for all the help.
