Have no battery power in coach with Converter Battery Switch in Battery.
Have power to switch on bottom terminal all the time (18V).
With switch in Converter position have power(18V) to the two bottom terminals.
No power at top terminal.
With Switch in Battery position have Power at bottom terminal (14v) and no volts on two top terminal
Top terminal never is powered and is a black wire that goes into wall behind kitchen sink. I'm thinking that's the problem, but have no schematic to trace the wire.
I was also thinking the middle terminal should be the power feed instead of the bottom terminal, but again have no info to verify.
Does someone have schematic or info on this ?
