I have a problem on my dad's race car trailer....or maybe his tow vehicle. He put new rear lights on his trailer and initially had them wired wrong. He brought the rig up to me today and I got his trailer wiring straightened out, but he has no brake lights, on the trailer or the truck, but it did when he left his house. we checked the factory brake light fuse on the truck and its good. Checked for power out of the fuse socket and that was good. Checked the inline fuse in the wire from the batt to the controller and that was good. Now, if you manually actuate the controller the brake lights come on, but not with the brake pedal. Anyone maybe have a clue whats going on here? Does the controller itself have an internal fuse maybe thats causing this? Any ideas would be appreciated.
Thanks,
Ken.
