Onan 4000 generator cranks but won't start
Hi all, I have a 2015 Cummins Onan RV QG 4000 generator. It has somewhere between 300-1000hrs (not sure, I've only owned it for about 2 years and it was a previous rental...might not be the origin...
Forum Discussion
Update: I reached the end my my troubleshooting abilities, so I brought it to my local RV mechanic. After quickly testing that it wasn't something simple, he removed the generator from the RV so he could remove the cover and dive in deeper. Long story short...he tells me the motor is shot. He thinks it must have overheated and some of the internals went ka-put (....he rattled off some internal components that had broken/etc that I didn't jot down). He tried replacing one item and put it back together but was still getting zero compression. He says it would probably cost more money to try to fix this one and it is time for a new generator...
He recommended I find a good used one if I can find one with a warranty. I liked his recommendation as I felt like he wasn't just trying to gouge me for more $$$ and he wasn't pushing me to go out and get a brand new generator.
I wanted to get some opinions from those of you out there who care to share....
This RV is a 2015 Thor Majestic 28a. Previous Cruise America rental. I've been very pleased with it so far (and I have another identical one). They serve well for how I am using them. This one has 140,000 miles on the engine. I can easily see holding on to this one for another 3-5 years. Everything else seems to be in good shape. Would you buy a brand new Onan 4000 generator and install it? Would you go for a used one for less than 1/2 the price?
I did some googling. There are two used ones locally each for ~$800. If I'm going to buy used, I will require seeing that it runs.
I also found these new ones...

and I'm sure I can find others. Seem like new ones cost ~$3300-3500.
Does anyone know of any companies out there who rebuild/refurbish Onan generators and sell them with warranties?
I'm not opposed to buying a brand new one. Just weighing my options and looking for opinions (which often times can be valuable and lead to discovery of additional options).
Thanks in advance!
