I have a trailer with a flat 5 for my surge brakes. If I plug the trailer into my truck everything works properly until i drop the trailer onto the ball. Once I do all lights go out and brakes do not disengage in reverse. If I take it off the ball they all come back on.
I tried two vehicles with the same outcome, also used two different balls/receivers.
This tells me its the trailer, but what? Im confused since it works when the trailer is off the ball.
Help Please!
