Right Tail Lights on Trailer and Vehicle Stay Solid When Right Turn Signal is On

Question:

I have rewired a trailer and everything works except when I engage the right turn signal, the car nor the trailer blinks however both the car and trailer are on bright solid. The right side works fine.. Could the ground be faulty? The lights are fine in running mode for night time.

It sounds like you have a short somewhere on your trailer. I would recommend finding which wire is your right turn and brake wire at your trailer connector using a circuit tester like part # PTW2993 and follow that wire back to the taillight. My guess is that you will find a pinched, frayed or damaged section somewhere on that wire. You should also check all connections to make sure they are making good contact.

It also would not be a bad idea to check the ground connections to ensure they are secured to a good, clean ground location such as the trailer frame.
