No Right Side Stop or Turn Signals On Trailer

Question:

2019 Palomino Solaire 25foot Travel Trailer I had no turn signal or brake lights at all. All running lights work. I tested my truck and all is good. Inside junction box on trailer I checked and rewired connecters and now I have left turn and brake light working, but no right turn or stop light.

In order to check the right hand brake/turn signal circuits on your trailer you will first want to obtain a twelve volt battery and then hook a hot lead up to the pin on the trailer connector which is responsible for the right hand brake/turn signals (see article). Once this is done you will need to also obtain a circuit tester and begin probing the right hand brake/turn signal wire behind the trailer connector, working your way back as best as you can to see where the power stops. I would be willing to bet the junction box is the failure point but if not test for power directly behind the tail light. If you get power directly behind the tail light then most likely you have a bulb out or a bad ground. If there is no power directly behind the tail light then you know you have an issue between here and the junction box.

If there is an issue with your junction box we do offer these, the Trailer Wiring Junction Box part # 38656.
