No way to find the voltage sensing circuit that controls the voltage.
There must be a circuit that drives the current to the rotor.
See what it's doing, maybe put a resistor in series to trick it out?
Probably no schematics that show what the board or boards do though.




Most of the simple generators only have a governed speed control. There
is usually a mechanical adjustment for this somewhere in the 'fixed
throttle'.

I have not looked over my 5 kw generator in a while, but my little 700
watt Harbor Freight does have an adjustment screw that can set the speed
of the engine.

This one has a bracket that the governor spring hooks to with about 2
dozen holes and you just pick the one that puts the right tension on
the spring.
That spring adjustment does not adjust the SPEED - it adjusts the
response to load change - in most cases. One whole one way from proper
and it sags, one hole the other way and it over-shoots

It certainly does adjust the speed and thus also the frequency. The
governor only looks at a vane in the cooling hood and the spring
tension is what determines how that vane adjusts the throttle plate.
