Now, however, the CHG feature will not operate with the Engine Alternator . . . and the battery voltage just keeps dropping.
To repeat, worded a bit differently:
The two battery strings are NOT normally connected together so charging (or discharging) one will not affect the other.
When the engine is running, something triggers a relay (solenoid) to close and make a connection so both will charge.
Unless there is a loose connection, something has failed in the circuitry that makes that connection when the engine is running. The most common thing to fail is the solenoid relay itself.
(Note: Oddly enough, my Damon Outlaw seems to charge the chassis battery too any time that AC power is present.)
