Here is the problem. I have a 18' car trailer that has brakes at all four corners. I'm a truck driver so the plugs are wired up correctly. When I apply the brake pedal in the truck the trailer brakes LOCK UP. And when I turn on the right turn signal the brakes will lock up in sinc with the turn signal. When I just use the brake controller to apply the trailer brakes the brakes on the trailer work great. This is driving me crazy. The trailer is only a year old. The fellow I bought it from owned the trailer about 1/2 year.
I'm thinking of repacing the scotch-locks and soldering the connections. Maybe that is the problem.
If anyone has any ideas to help please advise!
Thanks
