How Many Volts Should A Brake Controller Put Out? Expert Reply: Your brake controller should be getting 12 volts of power going into the brake controller. Testing the brake controller is fairly easy.
How do I test my brake controller output? 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 the Quickee Tester, part # 3808, you should get output to the controller side of the wire you severed.
How do I know if my brake controller is bad? Use a circuit tester, and check the red wire that exits the rear of the controller. This wire should only go hot when the brake pedal is pressed. If this checks out ok, then the controller is bad and must be replaced.
How many volts should electric brakes have? 12 volts
The engine of the towing vehicle should be running when checking the voltage so that a low battery will not affect the readings. Voltage in the system should begin at 0 volts and, as the controller bar is slowly actuated, should gradually increase to about 12 volts.
