I also have a brass cutoff throw switch, that was installed to the positive lead of the old house battery. When that switch was closed, the house lights were full bright.
Why would I have any lighting at all (albeit dim) in the coach, with that cutoff switch open? As is (or was, before I changed house battery), before I closed the switch, the house lights were extremely low. I would have expected for there to be no coach lights when the house battery throw switch was open?
Thanks, Tim

I was plugged into 110VAC behind our hangar. I haven't connected the new battery - yet.

Consider that the battery could be wired directly to the coach to supply 12V and the switch actually is switching out the converter. Now, with a bad battery, the lights would be dim because of the low voltage IF the switch is open. Close the switch and now the battery is receiving a charge voltage and the lights would also be receiving the higher voltage.
Could be wired this way because someone mis-connected the two leads, OR it could be intentional as a way to disconnect the charger from the battery. There may be a different switch elsewhere that is meant to disconnect the house from 12V.
Should be easy to figure this out with a simple voltmeter.
