You're the third poster in a month with the same issue.
The house batteries start the generator through a 100 amp DC breaker near the batteries as described by Paul. There is also a 50 Amp DC breaker that connects the house batteries through the battery disconnect (USE/STORE switch) to the DC buss and converter.
If the 100 amp breaker is tripped (or the cable to that breaker was not reconnected when the batteries were replaced) then the only way to get 12 VDC to the generator is from the engine alternator through the BIRD/BIM.
That's as specific as we can get without knowing the year, make & model of your coach.
