Maybe you guys can shed some light on this for me, Ive search all the previous posts but couldnt find an answer. I hooked my boat up to the tow hitch ball of my vehicle and I am not getting any juice to the trailer brake/running or turn lights. I put a tester up to the harness from my vehicle and Im getting a perfect reading so I know its somewhere from that switch back. If I hook the ball hitch into the coupler and lower the jack wheel it will come on, but after so many cranks goes off again, you can narrow it down to a half of crank and it will be on, finish the rotation and it will turn off. If you do this with the ball out of the coupler it stays on the whole time. If I pull the pin out of the pivot hinge for the swing away tongue it wont work, but the second the pin goes even an inch in (metal to metal) it works again. Like Im completing the circuit. The lights either work perfectly or not at all, no weak signal, no flickering. I checked all the wires and connectors and there is no lose/frayed wires or lose connections, I cleaned the hitch ball and always have dielectric grease on the harness plugs plus covers. I pulled the ground wire out of the swing arm of the tongue and examined all the wires and nothing is pinched. I would assume as long as the harness is plugged in it shouldnt matter if you crank the jack wheel or pull out a hinge pin for the swing away tongue, it should work consistently regardless. Would the ground that is connected to the bolt that has the safety chains be the issue? Does the ground connection have to be on bare metal or is it ok that it is connected to the black powder coating of the trailer? This is on a 2012 Margay. Any thoughts?
