I almost forgot to post this. Another Elk that I met in Newport last week had no power to start or run the dash lights. So after a couple of days of some work I think I got to the bottom of it with cleaning all the battery cables.
These pictures are of the power distribution box. It is a 2000 Fleetwood Southwind. The couple called us later to tell us they were not having an problems. I hope they get back to the Long Beach CA where they live without trouble.
