Am I Supposed to See 12V at the Tail Lights?
Re our Coachmen Freedom Express 192RBS: I have a verified measurement of only 10.39V at my left rear tail light. I am producing 13.9V from my 7-pin connector on our Ridgeline at the tail light term...

I think I might have misled some. By building a long jumper, and a simple spade lug connector to disconnect it when not in use, you can have a reliable voltmeter ground when needed. You can also use that as a temporary ground if needed during testing.
