House disconnect switch

I am trying to see what items in the coach are powered from the house Batt vs the eng batt.  If I switch off the main switch (by the door) will I be able to start and run the coach on the Eng Batt only, and use that to determine which circuits go where?
Thanks

Yes and no.

There are some circuits such as absorption refrigerator 12 VDC, propane detector, etc that are on the house battery bank, but are not controlled by the salesman switch.

The ONLY thing that runs on the start battery is the cigarette lighter plug on the dash. Unless you turn on the headlights or key. If you have 2, only 1 runs off the start battery. The other is on the house batteries.
