Probably getting off point here from the original post , but I have now replaced the generator blower motor. On our 86 air is blown into the generator compartment . There is a steel box on the front of the radiator with an opening at the bottom . This routes the cooling air through the radiator from the engine side , through the box and hot air exits at the bottom through a "scoop" which diverts air to the rear . 
Apparently someone ran over something long ago , bending the scoop which had to be restricting the flow . I have removed the scoop to be straightened and reinstalled at a later date . In the interim I can't see what it will hurt to run it with air exiting straight down . 
I know from other postings that some coaches draw air in from the bottom . I realize the importance of sealing the compartment as well as possible to ensure max available cooling air goes where it's supposed to .
I ran the genny for a good hour this morning , temp stayed at 150 ( if gauge can be trusted) , ambient around 80 .
Something I recently discovered : the generator gauges only work when main key switch is on . I'm thinking about adding a switch to power these gauges when we're parked. On our race weekends the generator will sometimes run three days straight , would be nice to keep tabs on it.
