AC is hopefully a tripped breaker (there is one on top of the Onan) or a blown bridge rectifier. If you need a bridge rectifier, the replacement has three of the pins twisted wrong and you need to take the socket apart and drill out the pin holes, put the plugs through the correct holes, attach them to the new rectifier, and then put the whole thing in place and put the screw back in it.
If the generator dies or gets shut down with the roof AC running, it will burn up the bridge rectifier.
They can be found online for a few bucks. Here is one that costs a bit, but will take more abuse than the original.

If the problem is not either a tripped breaker or a blown bridge rectifier, the other failure modes (assuming the electrical connections in the box under the Onan are not corroded or broken) would be a shorted or open circuited field or open or short circuited armature. Winding can be rewound (contact Jim Miller). Armature can not be repaired. You would need a replacement from a donor genset.
Connections between the genset and the main breaker panel can get corroded:
