Re: grounding problem with my enclosed car trailer???
Find the ground wire in the trailer's wiring harness (it SHOULD be white) and trace it to where it connects to the trailer frame. I suspect you'll find your problem along this path somewhere. A trailer shouldn't ground through the ball, although this is what it will try to do if the wired ground is lost. This can cause all sorts of erratic light and brake operation!
