Expert Reply:
It sounds like you have a problem with either your brake controller or the wire between your controller and the trailer connector. I recommend cutting the brake output wire about 6 inches behind the controller to test voltage there when brake contoller power is adjusted up and hitting the manual override on the controller. If you have proper 12V there, then use # 10-1-1 to run new wire to your trailer connector. If you don't have voltage at the controller, you will need to replace the unit.
