Troubleshooting Tekonsha Voyager Brake Controller with 12 Volts Constantly on Brake Output
Question:
I have a 94 GMC G3500 with the Voyager Brake Control already installed. When checking the rear 7 way plug I find that the Blue trailer brakes and Black Battery connectors are hot, with the ignition switch on or off. Shouldnt only the Black Battery connector be hot? The Voyager indicator light isnt on and no other indication that it is working. Checked the blue and black leads in the box and they both have 12 volts. Thanks

Either the wiring of your brake controller is bad or the brake controller itself is bad.
Testing the brake controller is fairly easy. Sever the blue brake output wire near the brake controller leaving enough room to reconnect it and then apply the manual slide. Using a circuit tester like part # PTW2993, you should get output to the trailer brakes. If the manual slide activates the trailer brake output wire properly, try the brake pedal. If the brake pedal activates the brake output properly also then the problem is farther back either in the vehicle wiring or on the trailer.
If either the brake pedal or the manual slide are not functioning properly you will need to test the wires going into the brake controller. Make sure you have power entering the brake controller on the black wire. On the red wire you will only want power when the brake pedal is pressed.
If there is power on the red wire before the brake pedal is pressed you have connected the red wire from the brake controller to the wrong circuit. You would then need to find the brake switch wire that has power ONLY when the brake pedal is activated.
If these connections check out and the brake controller is properly grounded then there is possibly a problem inside the brake controller.
I am including a link to a video that will show you how to test the wiring on a brake controller.
