What should the rotor reading be on an Onan?
What should the rotor reading be on an Onan?
Example: On ONAN spec ‘D’ and later, the reading should be between 20 and 26.5 ohms. Any less and you have a rotor problem $$$$. Any higher and you need to clean the slip rings and brushes. Read the service manual to be sure.

What do I need to start my Onan generator?
Getting the Engine Running Before any evaluation of the controls, regulator or generator can proceed, the Onan engine must have oil and fuel, be in running condition and the 12-volt battery charged. The electronic governor, 151-0752, on Models BGM and NHM, Spec B and later, must be functioning properly.
Example: On ONAN spec ‘D’ and later, the reading should be between 20 and 26.5 ohms. Any less and you have a rotor problem $$$$. Any higher and you need to clean the slip rings and brushes. Read the service manual to be sure.
What should the resistance be on an Onan generator?
Use the multimeter to check the resistance between pins 9 and 10 of the plug, the appropriate reading would be around 22 – 28 Ohms. If the reading is too low, there could be a short in the rotor. On the other hand, if reading is too high, it’s highly likely that there is a ground in the rotor .
Why is my Onan generator producing low AC voltage?
If field flash voltage seems pretty normal, the regulator could be the source of problem which you could determine simply by running 12 volts through a diode to the regulator pin 9. In the case the generator starts producing normal or slightly low AC voltages after that, the regulator is definitely defective.
What to do if your Onan generator starts then shuts down?
If there is no AC, proceed to check the field flash voltage through the field flash pin of the board. In the case field flash voltage is not present, the control board may be defective. If that happens to be the case, the “Onan generator starts then shuts down” issue could be taken care of by replacing the unit control board.
