No problem, but we may need to be clear on names of things to know what is happening.
There is a battery disconnect switch that is often at the door or sometimes on the left side of the dash. That switch controls a relay to connect or disconnect the power from coach batteries to the RV stuff like lights, fans and water pump.
Then there is a different switch near the driver that connects to what is called a "mode solenoid" and it connects both chassis and coach batteries together at different times.
When we push the dash switch it is like doing a jump start for a weak chassis battery from the coach! Jump start without needing cables!
This solenoid also closes when we run the engine, so that both the coach and chassis batteries get charged from the engine as we drive!
Both the solenoid and disconnect relays are usually side-by-side and often outside under a panel just behind the drivers seat. Often have a label and behind a panel of fuses or breakers.
We would need to know which of four models RV 2001 Adventurer to locate them on drawings!
The relay and solenoid are located just behind the batteries on some models and might look something like this?
