Swing Hitch Electrical Ground

[tentcamper]

Does anyone have a ground jumper between the swing part of the hitch and the battery or trailer frame?

Today I brought TM out of the garage. I had the camper setup high on the 4 stabs and the hitch swang back. So had to do a lot of jacking to lower it. When I swang the hitch back to the travel position and pinned it in place the elec jack would work for but for a second or two. After getting the meter out I determined the issue was a poor ground.

At least on my TM with the swing hitch, the only ground connection from elec jack is through the jack frame, through the frame to the battery. The electricity return needs to travel through the 2 pins that hold the swing hitch. But since there was no upward force from the jack. The pins and frame were not pinching together and supplying a connection.

I ended up installing a ground wire from one of the jack mounting bolts to the battery neg post.
