If the genset is running, it is producing power.
First check the circuit breaker on the genset. Make sure it is turned on.
If it is good, check all the breakers in the coach.

If you do not have an onboard receptacle, you either have a bad connection between the genset and transfer switch, or a bad transfer switch.
