I don't even see a regulator or a board. It must be inside the
generator head. There are just 3 wires coming out that go to the box
with the receptacles. You can bring the voltage up by spinning the
generator faster but it isn't 60 hz anymore. The voltage is 115/230 no
matter what the load is so there is a regulator somewhere. There
doesn't seem to be a lot of documentation on this.



The older generators do not have an electronic voltage regulator. They
rely on the governor of the engine to keep the speed/voltage/frequecny
constant.


If so, then Fretwell must have one that's screwed by design or somehow
faulty, because it's only putting out 230V at 60 hz.







The newer ones do have an electronic regulator. Here is an example of
how to adjust them.
