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 .

This is what normally happens when you start your genset.

Oil pressure and generator voltage build up within 1-2 seconds.
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.

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.
