I have a tracker single axle boat trailer and all the wires are run inside the frame. My right turn signal quit working and when I checked the bulb I noticed that one of the posts inside the socket was broken and the bulb was good. I got a whole new light assembly and while I was at it I got a new one for the left side too. I have changed them out twice before with no problems. I hooked everything back up and checked them out. The right side now worked fine but I had no turn signal or stop light on the left side. I re-spliced all the connections and re-checked the grounds. Still wouldn't work. I put the old one back on and still didn't work. I checked all the fuses in the truck and all are OK. I checked the circuit in the wires and I am getting power on the yellow wire coming from the truck to the trailer light harness plug. I checked the wire as close as I could to the plug on the trailer side and no power. I think I have it narrowed down to a bad connector plug on the trailer harness or the yellow wire is broken somewhere behind the trailer connector plug. I was going to come back about a foot from the plug on the trailer and cut all the wires and attach a new plug. If this doesn't solve the problem I don't know what to do. ANY SUGGESTIONS BEFORE I PULL MY HAIR OUT.

Thanks for the offer Tallman Dan. I sent you an email through the notebook. I got it fixed this morning. I was getting power all the way to the light so I thought it had to be a ground issue. I took loose the ground wire from the truck and the ground wire on the boat, sanded them down again and hooked it back up. Works like a charm. I guess I just didn't clean the gounds up good enough yesterday.
