The generac manual does not indicate how to adjust the 10kw model 5502 voltage. This model uses the small V-twin engine but is connected to the same generator as the 8kw model. To adjust the 8kw model the manual says to adjust the engine governor and the 12 to 20kw models have voltage adjustment potentiometer to adjust voltage. There is no mention on how to adjust the voltage for the 10kw model.
I'm currently getting 105v line to neutral and 210v line to line. Any help would be appreciated.
The instructions says the voltage regulator is automatic/digital. when you check the voltage is there any load on the generator? if applying load to the generator doesn't help, you can manually change the motor speed where the governor connects to the carborator, but it may change the frequency, but the regulator may fix it
applying load will increase the excitation current (its how the generator knows to start making electricity) anyways, i usually use a shop light for my load, you can't hurt them with low voltage. the adjustments for the motor speed will be mechanical (prob. a screw or linkage) i would call customer service if all this fails, they actually help pretty good

Usually answered in minutes!
the instructions say to NOT apply load to the generator until the voltage is in the recommended range. in this case (ie the 10kW set) the line to line range is 220 to 230 volts. i'm getting only 210 volts. How do you manually change the motor speed? and what is the best device or instrument to check the frequency? why would adding load INCREASE the voltage? i'm reluctant to add load which may harm my electronic devices and motors with under voltages.
I put a small load of a few lights on the generator and low and behold
the voltage shot up into the normal range. I continued to add load
including two freezers, a refrigerator, TV, two pumps and three rooms
of lights. The voltage stayed in range and I am now satisfied that the
generator is running properly. It appears that the electronic voltage
regulator needs to sense a load before it actuates the governor. This
is a nice feature, in that the weekly exercise will run at a lower RPM
and save a few gallons of LP gas.
Thanks for your help.
