Richard, the Cole Hersee transfer solenoid was "welded" in a merge position. I have had identical voltage readings on the dash for both engine and house batteries for some time . Now I know why. I had two spare solenoids. Now I am down to one. If we were boondockers, we would have discovered this I am sure . After turning off the converter, the "propane" smell from the past 3 weeks is gone. Magic !

Thank you for the chemistry lesson. It is appreciated. We are off today to order all (4) new agm batteries. It is a 110 mile round trip across the Chesapeake Bay Bridge to the nearest O'rileys, so I may end up doing business with the local Advance Auto Parts. Yesterday we ordered a new converter from Amazon.

Update.....Went to Auto Zone today. 8D agm batteries aren't available according to them. Off to Orileys tomorrow to get them ordered
