Generac 0E8309 3.9L Ignition Module Controller PCB. Please note when replacing this ignition module, take a close look at the bad module’s capacitors. If there is a small ‘blow hole’, you most likely have a bad field diode which is allowing field voltage back into the 12V system when the unit shuts down. The diode should be tested/replaced BEFORE installing a new ignition module!
Generac replacement parts will also usually fit the following Generac branded generators: Honeywell, Guardian, Siemens, Carrier, Watchdog, Centurion, Eaton & Bryant.
