Sounds like you have a short to the red wire of the brake controller. This circuit is supposed to only see voltage when the brakes are applied. If this circuit has voltage all the time it's going to tell the controller to be constantly applying the brakes. If you test the circuit and it doesn't have voltage all the time the issue then would be a bad brake controller.

For a brake controller replacement I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes.
