See that's what i was thinking is that it makes ground though the ball hitch too. So i wired a plug on it. and put my battery charger to it and i just cant get the lights to shine! lol.
We were going to get a magnetic set of lights as a temporary solution also so we could use it. But now my wife is telling me to pull the siding and just rewire it.
Unless the trailer is rotted and you plan on pulling off the siding for another reason, don't do it. The chances of something going wrong with the wiring in the walls is very slim. The other poster had a good point...does the hitch double as the ground? If it does I believe the lights need to be grounded to the trailer frame either via a white wire or sometimes directly by bolting them to the frame similar to small boat trailers.
You can use a tester not only to check voltage but to also test continuity from the trailer plug to the light receptacles if you have a jumper wire.
I once spent an entire day trying to resolve a trailer light problem only to find that a wire had worn through and was contacting the frame of my truck and short circuiting...the trailer was fine. Try one of those little 4-flat tester plugs to make 100% sure the tow vehicle is working properly. Just because all the lights work as they should on the vehicle by itself doesn't mean there isn't a problem with the wires that run to the trailer receptacle.
