Having problems with my Power tech generator

1) as soon as the generator fires on with the switch the squirrel cage fan starts up in the next bay to blow air across the radiator, then in 1 second stops and never starts again leading to overheating and shutdown.

2) The generator now for some reason does not start charging or supplying electric power to the coach. In the past I would hear a click and the generator lug slightly and we were charging. Now nothing.

We did just get the generator serviced and hope it could be something stupid.
