Onan 7500 Quiet Diesel Trouble Code 32 FIXED
My 7500 Onan is not turning over. It is throwing a 32 trouble code. I have checked the 3 fuses under the plate that covers the radiator fill cap. It is showing 13.2 volts on the lug at the back ...

I would do a complete maintenance on the batteries. Remove and clean every battery terminal and any terminal between the battery and the genny.
Also be advised that a 32 code can be caused by bad brushes. Think about it, armature speed is measured by the output and there is no other connection to the armature than the brushes. I saw mine torn down after twice throwing that code, the first time it was a bad rotor bearing and the second time the brushes weren't properly aligned on the slip rings.
So before you call Onan, (they can be very helpful) do the battery maintenance.
I just re-read your post, if your genny won't turn over at all, of course it throws low RPM, I don't think it can throw any other code. And maybe someone else has the trouble shooting/repair manual. Try a Google search.
