Russ, hope you guys are having fun on your adventure. Baxter is helping me fix the coach. He puts his nose on the back of my neck just as I am probing for voltages. Bzzzzzzzzz!
Got the switch replaced. Turns out it is from 70s era GM truck. Same symptoms. The guys at the factory are going to call me back with more ideas.
I am in rural Mississippi and am enjoying the stay except for the banjo music in the distance!
Cheers,
Bill
