1) Plugged in to shore power, coach and house battery charging?
2) Engine running, coach and house battery charging?
If this is the case, what is this disconnect relay used for and when does this come into play to separate coach from house battery?
1) maybe, plug in and check the chassis battery after 48 hours of no use. 13.2+ is being charged.
2) all motorhomes charge house and chassis batteries from the alternator.
Relay could be a BIRD to charge either way when a charging source is detected.
Could be a cut-off switch to remove parasitic loads from the house battery during storage.
Could be a boost start that temporarily connects the house to the chassis to start the main engine.
