You are asking for the impossible since all RV's are wired differently. I've owned enough to accept the fact that what they did in the factory does not always make sense. On my Monaco coach, the "salesman's" switch is marked "ceiling" and is momentary to energize a relay. The very next year, the switch is still labeled the same but is an on-off type switch that energizes the same relay.
When the engine is running on my coach, the isolator controls what the engine alternator is charging. If both the house and the chassis battery needs charging, they will both get charged, regardless of the position of the salesman's switch.
ON shore power I believe 12 volts is needed to control the monitor screen on my Xantrex inverter/charger, it will not charge the batteries if the salesman's switch is off. There will still be 120 volts at the outlets since they are bypassing the inverter.
As I said, all RV's are different as I have seen different wiring on coaches like mine and built the same year. The factory wiring diagram is just fiction, as are the fuse labels.
