daughter Report post Posted July 6, 2012 We have a 2009 Four Winds Hurricane 35 Ft. with a Guardian 5500 Generator #5412. We have both Air Conditioners on when driving. After about 1 hr. generator stops. Temperatures have been above 100 degrees. What should we check? Share this post Link to post Share on other sites
dickandlois Report post Posted July 6, 2012 Some generators have a high temperature shut down. I'm not up to speed on your particular model regarding if its air cooled or water cooled engine. The fact that you are running both AC units in the current temps. is putting a very heavy load on it. You could try to run just one AC unit and see it the Generator runs longer. A little cool is better then none if the Generator decides to quit entirely. Rich. Share this post Link to post Share on other sites
desmo Report post Posted July 6, 2012 I had a generator problem that only happened when I was driving, the low oil level sensor would activate under certain conditions and turn off the generator. Later found out the dip stick was not properly calibrated and was showing full when it was a quart low. Check and see if you have error code read out on your generator.
