This interconnect relay in the BCC controls battery charging to both chassis and coach batteries.
If you don't have a BCC you should have a Trombetta and BIRD under the hood toward the driver's side. These two devices control when and under what conditions the coach and chassis batteries are charged. The attached picture shows the Trombetta with red wires and BIRD (rectangular box next to Trombetta).
One point -- The USE/STORE switch must be in USE for the coach batteries to charge regardless of whether you have a BCC or BIRD/Trombetta.
So regardless of BCC or BIRD/Trombetta, both coach and chassis batteries should charge whether on shore power, generator power, or driving down the road with charging power coming from the engine driven alternator. Again, I can't stress this enough -- the coach batteries only charge when the USE/STORE switch is in USE (regardless of charging source.)
If your switches are positioned correctly and either the coach batteries or chassis battery are not charging, something is probably hooked up incorrectly and should go back to the dealer.

We have the BIRD and TROMBETTA on our 2016. I am having trouble figuring out where my issue (if I really have one) is. Right now both the coach and chassis are charging on shore power. The issue, I think, is if I start the engine while on shore power, the batteries disconnect from each other (as they should). And the chassis reads 14.4 from the alternator. However, if I stop the engine, the chassis battery doesn't reconnect to charge from shore power. I traced the chassis battery dropping to 11.6 still no charging. If I disconnect from shore and start the generator, no charging the chassis battery. However, if I disconnect from shore, turn off generator, and start the engine, I have 14.4 at both chassis and coach battery (again as I should since both are charging from the alternator). Then, if I shut off the engine and connect to shore power, I then have charging 13.1 at both chassis and coach. So it looks as though it takes power coming from the chassis to reset the relays for charging. Not sure if I have an issue, or just shouldn't start the engine while on shore power. THOR says the converter SHOULDNT charge the chassis, but at the moment it is. So, I am not sure if I have an issue or not.
