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
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.
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.
