Onan Adjustment
Is it possible to adjust the voltage output on an Onan 4K ? Mine runs ~109V no load, and sags to 105V at half load.

gmc toy man,
Yep. Brains it what it took and you use yours :)
Unless the regulator circuit board has two potentiometers on it...
You're stuck...
note: Regulator adjustments when made field adjustable are USUALLY done as a pair -- the first being voltage, the second being response time.
The sensing network of the voltage regulator is malfunctioning. A voltage divider network or voltage comparator. Neither is repairable.
Be certain you do not have a fault in the neutral circuit of the generator. Unplug. Stop generator. Turn off all breakers. Unplug everything that has a plug.
Measure ohm resistance between neutral and the rig's earth ground wire circuit. What do you see? Neutral is never switched folks, so the test is viable. A full-on bond, can drive some generator regulators to err.
