- Trailer Tail Lights Go Out With Headlights On And When Brake Pedal is Pressed On 1993 Chevy 3500
- It sounds like you have a ground problem on the trailer. However, there also could be a problem on your tow vehicle.
We can isolate the problem to narrow the search a bit. Disconnect the trailer from the truck. Using a circuit tester, like part # 3808, test the 4-Way connector. Clip the tester to the truck frame as your ground, and test the brown, yellow and green wires to make sure they function properly. Brown is tail lights, yellow is left turn and brake, and green is right turn and brake.
