Trailer light problem?
I just installed a Peterson universal trailer light kit on boat trailer this morning. I connected it to my truck & I discovered that everything works fine except the brake lights. The hazards work, turn signals, but when I press the brakes the light goes off instead of getting brighter. Any ideas?
It may just be a bad ground. Sometimes if the ball or trailer hitch dirty/rusty it do this. Try pulling it around with the truck and see if it not start working.
If, the wires are correct. Blinkers are the Brakes too. So, if the blinkers are working the brake lights should work also.
If, you have to, you can connect a wire to ground on the truck and one to ground on the trailer. Most plugs have the wire (White) it just never connected as the trailer should ground on the ball.
