Well RB1 didn't do it, Makes me think more, so do you suppose it could be the tone board. It would be a surmisation, but, if it stays at the floor I can open doors all day long, then make a run, Dead. Even when it homes it pukes without doors, so that takes the car lantern out of the equation. Losing sleep over this one..... Rolly, unfortunately I don't have a burner, and yes they are covered. New MCB, almost had that AH-HA moment when I replaced it though. the old board was discolored where the door inputs were. DOL and DCL change states correctly.
