Trailer brake issues
Helping my father with his trailer and I am stumped. He asked if I would help adjust the brakes on his toyhauler because he didn’t feel they were working while driving. We jacked up one wheel and the brakes had a slight drag like they should. Pulled the pin and it locked up. We did this to each wheel and they worked as they should. We checked continuity at the umbilical and all the wires were good to ground. We then switched to the truck and we have 12 volts when the brake controller is activated. Does this mean the controller isn’t working correctly when the brakes are applied with the pedal? How do you check voltage while hooked up and moving to see if power is being supplied?
