Thomas got the generator running for me but we need to know what to set the Governor at for the correct rpms #nauticinderella

Sorry Cindy. I don’t have a clue on that one. Do you have a manual. Is it an Onan ?? You could always call the manufacturer. Or, In these times and days. Google it. That’s what I do.
I’d put a voltmeter on it and set the RPMs to the point where it delivers the correct voltage.
Many are 1800 RPM. I think not only Voltage, but Hertz (HZ – Cycles per second) may also be a factor. Most AC electrical systems can vary from 110-125VAC, but HZ should be 60. This can affect certain electrical equipment.
Like Kent said. Diesel presumably? Should be 1,800 rpm because it’s a multiple of 60 Hz.
You can google and download the manual- that way you can set it the way the manufacturer wants. I did that for mine, way better than advice off FB- not saying any of it is wrong, just a better practice to get correct info from manufacturers
Onan should be 1800 RPM, but check since there are some that operate at 1200 RPM. The hydraulic governor will control load and maintain RPM after initial setting.
Thanks guys I’m trying to Google stuff with my phone and down here helping the diver that’s patching the bottom. The marina is going to cut me loose from the dock today at 2 o’clock
Good luck, Cindy. I’m one of (probably) many who’ve been following along since the hurricane. Keep up all your great efforts to save your Connie!
1800 rpm is a safe place to start
It depends on the genset ratingnad engine configuration. Up to 12KW or so many are 4-pole machines and they run at 1800 RPM full load – a bit higher at no load. Above that, many are 6-pole machines that run at 1200 RPM.
Cindy, Guarentee that you can get some help over on the SmokeStak. All the old Onan guys seem to gather there.

Here are ALL the Onan Manuals available:

Cindy, what model and capacity is that generator? Is that a 15 MDJF or a 7.5 MDJF? I cant quite see how many cylinders it is.. Looks like a 4 cyl?
I posted on the forum asking for a bit of help.. lets see if they can come up with anything..
first reply back on the SmokeStak..
“What is wrong with it right now? MDJC and MDJF are pretty much the same unit. Runs at 1800 RPM”
Looks like the same gen set I have. Mines an onan 7.5
But not sure
A note from one of the folks on the Stak:
“That is a MDJF for sure , do not know what vintage since I can’t see the gen end but based on the fuel solenoid I believe it to be a YD gen end. The video is not really long enough to be conclusive but it sounds like a fuel supply/starvation issue with the surging of the engine RPM. I would put a meter on the output and check the HZ but it sounds like it is going up and down, may be a restriction in the fuel supply , is there a fuel transfer pump which needs to be powered up to run? “
He has offered to talk with you and see if he can walk you through some troubleshooting steps. I can send his number if you like.
