Thanks Tree Seeker, I've seen a couple of those already, and really don't get me where I want to be. They are mostly about batteries... not the wiring itself. Maybe someone has previous experience or advice on the subject. All the wiring is, of course, hidden. In walls, ceilings, panels, etc. One of the items I can't seem to find, is how the DC works. My thought is it grounds to the Frame... but I really can't find a confirmation. If that is the case... Can't I just run new grounds to the frame? Does that cause problems? I can't 'find' where the current DC is connected to the frame anywhere... maybe that too is inside the wall? What is the accepted means to add a new ground? How do I get it to the frame? If the Engine battery is grounded to the frame... and the house batter is grounded to the frame... wouldn't that cause some weird problem/hazard?
