This is due to the "BIRD" only used in motorhomes.
It is a Bi-Directional Isolation Relay Manual and schematic attached (see page 4). With the ignition on and the engine running (alternator providing power) the isolation relay closes and provides charging current to the house battery.
Note: In this case power is only allowed INTO the battery; not out if the disconnect is enabled.
As to the moniker "Old FART" - I may be the only member of the forum who is ACTUALLY an Old Fart.
As a retired Federal Air Reserve Technician (FART); I am indeed an old FART.
