Hi Joe.

I doubt your generator is actually running at 220. The high temp shutdown would kick in, and the computer would turn it off. Plus you would be boiling the coolant out of it like crazy.

Do you have an infrared temp gun? If so shoot the top of the radiator and the engine block to verfiy what the guage says. We all know those guages become wonky with time because of bad grounds and sensors.

Do check the coolant.

An obstruction, like a bag, or coffee filter, covering the inside fins will cause very high head pressures. These units do not have sensors for shutting down on high or low pressure. The high pressure draws an excessive amount of current which puts a load on the generator and trips breakers eventually.

It is very hot this summer almost everywhere. To others with SCS units, try this trick. Raise the coach as high as it will go to allow more air to circulate under the coach. I have found a five degree difference in the temperature of the exit air from the ducts with the coach being "on the ground" and up as high as possible in the front.
