I wanted to give some first hand experience on the extended operation of an 802a I sold 2 years ago. This generator is primary power for a customer, who has been building his home off grid for the past 2 years. He uses the generator to run his camper, well pump and small shop continuously. He just logged over 17,000 hours without any major problems. I sold the unit with around 200 hours on it and the only thing he has replaced is the alternator for the batteries. He logged 12,000 hours before the alternator had to be rebuilt only because the bushes wore out. The water pump has started to leak when shut down but stops after its running. I think we can get another 1000 hours out of the pump before it needs to be replaced. Just wanted to give everyone a testimonial of the longevity of these units.
