Ok leaving friday to the hammer with two rigs on my gooseneck and i cant get the new brakes to lock up or even work very much. I hooked 12v to each wheel and the brakes lock right up. I have a junction box in the middle of the trailer so i tested it there with 12vs and it locks up if i hook the ground and the positive up. If i hook it up to the truck i cant get the brakes to work more than just a slight tug. I tried adjusting my prodigy controller and it goes to 6.0 but it still wont stop the trailer. Should i be getting more volts from the prodigy? The wiring is brand new 7wire jacketed wire so no crappy wires. Should i be running a ground from the brakes to the plug or can i ground it to the trailer frame? Could that be a source of the problem? Sorry if its vague but im just burned out on chasing this brake problem down.
