Having problems with my generator, Onan 7500....runs OK until I turn my A/C on. When it loads up the generator will run about 5-10 minutes and kill. I am getting three blinking lights on the switch ...

Check for airflow over the radiator. Depending on how it's been used, you can accumulate a lot of garbage that will block the airflow. Had this happen more than once. It would run ok on a 1 ac, but load it up and it would eventually overheat and shutdown.
