How do you test a generator stator?

How do you test a generator stator?

To test a brushed stator: Isolate the stator by removing the connections to the AVR (automatic voltage regulator) as well as the wires running from the stator to the electrical panel. Set your multi-meter to test resistance.

Can a generator stator be repaired?

Our skilled and experienced technicians can repair or rewind your stator. We take the time to provide accurate and reliable repairs on your stator.

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 .

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.

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.
