Exercising the Generator

I have not been exercising the Onan generator over the summer as I should have been. I am supposed to run it for 90 minutes once a month under a good size load like the air conditioning. I have only done this once since May.

I also hardly ever look at the hours gauge telling me how many hours the Onan has on it. Today it reads 709 hours. The rig is 11 years old so that is only 65 hours per year of use. Not that bad but I wonder what the life of these things is and if I will be facing an overhaul in the near future.

OK, a little Googling tells me the 4000 watt Onan should be good for up to 5000 hours. I'm good!


  1. At that rate you'll have 60 years left?

  2. Damn, I forgot about it and left it running for 2 1/2 hours! Sure is cool in there!

  3. Our genny has only 500 hours on it at 17 years old think it should be good for a while yet. Keep up the exercise it's good for y'all

  4. Our rig is 8 years old and the generator has 12 hours on it. I run it every fall when I change the oil. I don't think we'll bother with an Onan on the next trailer.....
