Strange brake controller issues
I recently installed a brake controller. I hooked it into what I believe to be the brake switch near the brake housing.
It measured 12V when the brakes were pressed and 0V when the brakes were off. Disconnecting the switch disabled the brake lights.
However now, when the vehicle is off, if I press the trailer brake button on the controller the following strange behavior happens:
- Brake controller outputs 12V to the brake line that the switch is connected to (expected)
- Brake lights don't come on
- Instead, dash lights come on (as if I had turned the ignition).
Am I doing something wrong? Did I wire this brake controller to the wrong place? If you've installed a brake controller, where did you wire the brake switch input/output line to?
