Question:

Lights flickering when hitting bumps. I wiggled the trailer near the coupler and they go on and off. So it has to do the grounding with the ball. But how can I fix it

Expert Reply:

In order to fix the issue with your lights flickering you will want to pick a good spot on the trailer frame near the coupler and then run a ground wire from each of the lights as well as the trailer connector to this point. If you need to extend the wires you can use part # DW02359-1 and part # DW05744-5. Once you find a good ground point, sand the surface down, twist the wires together after you have removed part of the jacket, and then attach it to the sanded surface with part # DW05741-1 and part # 101131802. This should then fix the issue you have with the lights flickering as you go over bumps.
