Lots of time, with grease, there is no connection.I'd be very surprised if it's a ground. When your trailer is attached to your tow vehicle, the trailer/vehicle connection is basically a ground.
I agree, with 12v systems 90% of the time it's a bad ground...Lots of time, with grease, there is no connection.

15 years old? Don't mess with it. Rip it all out and replace with new. Much easier and cheap. But you have like 20 other responses telling you to fix it.. How do you know which advice to take?

now that makes sense !
it may take an hour or so, but once you have a new hiring harness and lights

When you are ready to remove all the old wiring, it is good idea if you use some string and attach it to the wires, so that when you pull it through the frame, you leave the string in the frame. You can then attach your new harness to the string and just pull it through.
