I'm not sure I can help much but there are a few points that might help.
The cooling fan for the radiator will be 240V and fed from a breaker in a seperate enclosure inside the generator box. There will likely also be a breaker for fans mounted in the back of the box to move air inside the box. This is combustion air and rejected heat removal for the engine. These breakers are ahead of any power fed to the coach which must go through the transfer first.
You stated " the indicator light that tells you the generator is running" was not on. I believe you are refering to the AC powered pilot lights, if the transfer isn't closed to the generator side no power will be going into the coach at all! There is also a pilot light on the control switch on some sets that is 12VDC powered, if it is not on then the engine isn't running.
The transfer switch (on your coach) does have voltage and frequency sensing so if your voltage output of frequency is low, the switch isn't going to close. Power Techs have had issues with their governor control allowing the set to run at reduced speed and the voltage isn't high enough to pass the XFER voltage sensing network.
It is very difficult to diagnose via email however I hope this might clear some of the fuzzy parts.
