I am just purchasing the motor home and the previous owners do not know when the generator was last serviced. But something everyone needs to remember about oil, is that even it just sitting in the oil pan it breaks down. So it is not all about the hours but also about time.Re: Onan 7.5hdkaj11502g generatorI spoke with a tech for my generator and he told me that if the oil is broken down and the generator is not getting its proper protection from it that the generator will shut down and give the 3 3-2 code. I did an oil and filter change today and the generator has been running for over 10 hours without shutting down.Re: Onan 7.5hdkaj11502g generatorThanks for that link.... I am still, company staying in motorhome until gen quit. There is 630 hours on the unit.Onan 7.5hdkaj11502g generatorI have the above generator and it has been running great, until a few days ago and it just shut off. I found how to get the fault codes and I got 3-32 fault code. 3 is the primary code and 32 is the secondary. The generator will start and run for anywhere from 5 minutes to 2 hours. Any Ideas ??
