2007 F-250 with factory brake controller. Pretty straightforward issue I think, electric trailer brakes not working, manual brake slider works good, 12 volts at trailer magnets. When brake pedal is pressed only 1-3 volts at magnets and tested at back of brake controller as well with same results. So is the controller bad or could it have something to do with the brake switch at brake pedal?
