Do any other DC house loads have the same behavior? Like the overhead lights? If so it may be a failed isolator solenoid that is the cause.

Can you download your coach diagrams from Winnebago like we can for Thor to determine where it is supposed to get power from; and what could possibly be causing the cross-connect?
Yes, I will work to get my electrical diagrams from Winnebago. I know I can get and I have seen, but I have been kind of avoiding I need to learn how to use it better than I do.

During interim, when my Store switch is set, there is nothing ON in coach that I can see until I stumbled on this little light. Even the carbon monoxide detector goes off.

The only none factory leads coming from battery posts is one that was installed to feed EC-30 House voltage, and the other installed to feed the EC-30 Chassis voltage. But it worth noting that EC-30 has no power when in STORE mode.
