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.
Onlyu on the cheapest of engines, MOST use a flyball governor in the
crankcase - and although moving the spring DOES change the RPM the
MAIN effect is to change the response.

I am not sure what you mean by response but this thing has about 30
holes and EVERY ONE changes the engine speed.
Governor response is how much the throttle opens when the RPM drops
a given amount - too little response and speed lags under load. Too
much response and speed increases under load - in other words it
either undershoots or overshoots.
: governor hunting orsurging up and down. Most of the time this is not the problem of thegovernor, but a partially plugged carburetor, usually a pluggedidle circuit or worn linkage. If you can rule out these causes andhave checked the adjustments I talked about above, then you may havea governor that is set too sensitive. In other words it reacts tooquickly and over compensates for the speed. Many governor arms haveseveral holes in the arm to change sensitivity. By moving thegovernor spring to a hole further away from the governor shaft youwill make it less sensitive. Before playing with this, check therepair manual for the engine you have and see if it has a way of adjusting sensitivity. Sometimes you may have to change governorsprings, etc.

for more information.

Basically adjusting the STRENTH of the spring regulates the RPM -
adjusting the length of the generator arm regulates the governor
response.

The holes are in the fixed bracket the spring hooks on, not the arm.
That does change the tension on the spring
