When I had my MC-9, I was having a problem with my generator overheating. It would get so hot that it would shut down about 15-20 minutes after I started it on a hot summer day in southern California. I would have to run it with the luggage door open which allowed the excess heat to escape when parked. When driving down the road it would not overheat as long as I kept moving. But within about five minutes after I stopped the bus it would shut down every time. After it cooled down, I could reset the heat pop-out circuit breaker and it would restart again. However, as you can imagine, this is a bit inconvenient as well as very frustrating, and not good for the engine.
