OK...I stand corrected. After having this coach for 9+ years, I'm still learning about it. My coach did have a means of charging the house batteries when the engine is running,but it did not work (until I cleaned up the wires).
While installing new 6 volt batteries (I believe they made it 14 years), I cleaned up connections and got curious about a small black box above the aux start relay. After removing it from the wall, I could see the label "Intellitec Isolator Relay Delay". Some research reveals this is supposed to close the relay therefore charging the house batteries as well as the chassis batteries when the engine is running. Using the handy voltmeter, I could tell it was not working. After cleaning up the connections on on the relay, it is now working.
Unfortunately, there is nothing in place to keep the chassis batteries charged when on shore power. This will be a future project.
