Generac 79018/0790180SRV PTO Voltage Regulator AVR.

If your Generac Generator's output voltage is too high, this is most likely the bad part and it will need to be replaced.

This was used on special PTO type generators.  All versions of the 79018 have been replaced by the 0790180SRV version.

Important Note: This particular regulator may now be shipping with a set of leads (wires) hanging out, instead of the normal connector. We're assuming that it was a connector supply issue and they made the change to continue to produce these regulators. You can purchase just the connector if you'd like to add that to the wires to fit the existing orange connector on the generator's wiring harness. These connectors plug into each other and have no male or female designation. They simply flip over and connect to each other. This change may revert back at any time without notice.

For the connector, see here:

*Please Read*

These (and all Generac Voltage Regulators that are adjustable) do not come from the factory calibrated for the correct voltage!  You will need to properly adjust this regulator once it's installed in the unit.  This will require a high quality digital voltage meter and a small flat head screw driver.

These regulators include an adjustment procedure sheet which will explain what steps are needed to adjust the regulator.  It will require that the unit be loaded to near full load to properly adjust.

If you are not comfortable with anything mentioned above, seek a Generac Authorized Dealer to assist with the install and calibration.  Dangerous voltages are present when working with generators!


Generac replacement parts will also usually fit the following Generac branded generators: Honeywell, Guardian, Siemens, Carrier, Watchdog, Centurion, Eaton & Bryant.
