I would have thought the chassis batteries would start the gen.
Also, regarding the "bird" relay. I was plugged into 110 shore power all week and yet the chassis battery went dead. The battery is good and came back to full charge after jumping it and driving home. Emergency start button seemed dead as well. I assume the house batteries did charge during that time since everything worked fine. Is it possible the "bird" allowed the house batteries to charge but not the chassis battery?

The BIRD and Trombetta in many Axis are supposed to charge both ways. However, my 2016 was miswired at the factory and the house batteries did not charge from the alternator. I had to rewrire my system for it to work. Easy way for you to check your system is to check the voltage at the two terminals of the Trombetta. If the engine is running or the coach is on shore power or the generator is running, the voltage should be the same at both Trombetta terminals - i.e. both battery systems are being charged as they should. If the voltage is not the same either with the engine running or on shore power/generator then something is wrong. Check and let me know. How I fixed mine is in a thread back in 2016. Search BIRD or Trombetta and you might find it.
The generator is wired to the house batteries.
