Is this how it should work it should work on our Scenic Cruisers (his is a generation newer than both our Scenic Cruisers)?

Now to jump start the engine with the house batteries just press the rocking switch down and hold it for a few seconds and it will crank right up.
Now while I am hooked up to shore power only the house batteries get charged up with the inverter/charger on my Scenic Cruiser.

On Shore Power, our Chassis batteries do not get charged, only the Coach/House batteries (I've check the voltage on both banks several times). The Converter/Charger only connects to Coach/House batteries though that bank is connected towards the BCC (and/or a isolator Relay) and perhaps the system should the Chassis bank on Shore Power. I just don't know if it was designed to do so.
EDIT: On further thought, I think the Converter/Charges (under bed) wires go towards the BCC (front of Coach, Driver's side) and not directly to the Coach/House bank at the rear Drivers bay. I may have to take the time to trace those wires.
With Engine running, the Chassis batteries get charged but not the Coach/House batteries. However, I may have checked the voltage at the Coach/House batteries (with engine running) when the Chassis batteries were still low and the BCC didn't switch over yet - assuming the above quote is how the system is supposed to work.
Our Coach doesn't have an inverter, just an upgraded converter/charger.
I looked through your onedrive. Did you document your B.I.R.D. repair/upgrade? I'd be interested to know the details of your upgrade/repair.

Expensive relay as it has to be a continuous duty relay vise a momentary duty like a starter relay.

I hear the click when I press that dash button but I have never had the voltage measured while pressing that button. I will have to figure out which bank to measure - actually I need to find that specific relay location first and just test at the relay.
