Where to put ground wire?

Hello guys,

We have a 63 trotter for the second time. Bought the same trailer I sold twenty years ago. A stange feeling when we first looked at it. I paid twice as much for it as I sold it for. Anyway. The ground wire was connected to the copper water lines. I am replacing copper pipe, and I need ideas about where to put the ground wire for the battery. So, what do ya'll think?

That's interesting that they would use the plumbing as the main grounding point unless there is a point where the copper is tied to the trailer body with a positive connection.

The 12 volts system grounds out through the trailer body. Considering the age of the trailer and the fact that things may not be a tight as when built I would make a connection to the frame and one to the trailer body. If from the inside you can get to one of the trailer body frame members that is heavy enough material to make a good ground to and assuming the rivets at tight throughout the body you should have ground throughout the trailer.

Thanks for your input. I like the idea of going to the frame and body. I looked earlier at how to get to the frame, I am going to need 60+ inches. In shopping around I discovered small engine ground wires, big mowers,etc, they use #6 wire that is already made up with lugs on each. They come in lengths up to 72". Do you think there would be any problems with going that far to get to the frame I want the length to hide the wire keep the service box 'pretty'.
