Pull the power plug, gen off, disconnect any solar and disconnect all wires from the li negative post. If the house 12V items still work then someone changed the wiring as very unlikely Newmar would wire it that way and a DC clampon meter would be very useful to isolate the problem.
13.4V on the chassis battery doesn't mean it's charged or any good. Load test it. I'd guess it's being charged by the DC DC converter which is inadequate for enought charge in the time frame for a engine start.
Chassis batteries were just installed. they hold a charge just fine.
No Solar..
The house system is now working, every light in the coach is on, the furness motor is on, and the microwave is cooking dinner...
the Chassis batteries are holding 13.2 VDC for the past 4 hours.
I think it's fixed.
Thanks for the help.
