I agree.Old boat trailer. Working on it anyway. I would replace the entire wiring system, not just the plug.
So you have new lights, new wires (come w light kit) and they wont work?
Redo the 3 grounds. Wire wheel the ground spots, use self tapping bolt. There will be a ground at each tail light and the tongue. Anyway, then paint them or put jb weld on there to keep it from rusting.
If your ball is rusty spray some wd40 on it.
I gave up messing w old wires a long long time ago. If trailer lights start acting up, will buy a kit and replace the lights and wires. Life is too short to mess around w stuff like that when you should be fishing.
Frustration city. Sounds like a good idea.Yes, all brand new wires and new kit. Some guys on here made good points about the bolted trailer frame and rust and I tend to agree with them that I’m not getting good connectivity between the bolted sections. I’m going to run the ground all the way from the plug to each light instead of having three separate small ground wires.

Others have said that you have a bad ground. That is your problem. Your test light is lit when you are clamped to the trailer and probing your ground wire. That's showing you you have a voltage drop on the ground side. I'm an auto mechanic and deal with electrical issues on vehicles every day. On trailers i always run all my grounds back up to the trailer plug that way you are using the truck ground and not relying on a rusty crusty trailer frame.
you could also run a jumper ground wire from the sections of trailer the lights are on and connect all them all with some self tapping screws, crimp ring terminals, and 5ish inches of 18 gauge copper per connection. At the end of the day your lights all need to share a common ground.Yes, all brand new wires and new kit.

lBreak Out Another Thousand and “and there are only two good days when owning a boat, the day you buy it and the day you sell it.” I just keep telling myself it’s for the kids
