Do starting batteries charge from shore power?

[Chuck v]

The generic GS Owners manual is worthless in trying to address this question. Even the most high level schematic representation of the coach's electrical system would be useful here, but as we all know the manufacturer is unwilling to come "clean on" this topic of electrical schematics.

I am storing my coach in a building off site during the winter months (this is the first winter we have owned this Tour Master T-40C...) When I went to do a little work on it today the building owner wanted it moved a few feet to accommodate some work he was doing on the facility. The engine starting batteries were down (not completely dead) so I used the EMG Starting switch to utilize the house batteries which allowed the coach to start right up.

I thought that all the batteries were maintained in a charged condition by the shore power connection, regardless of the state of the coach and chassis disconnect switches. Obviously I ma not correct in that presumption...

How does it REALLY work? Thanks in advance for any input.
