Generac 10000exl service manual

I need help with changing the speed on subject genny. It had B&S engine #350445.
It puts out only 98 Volts at the unit. In the house it is 94V.
I have no way to check the frequency. I can't tell if there is a Voltage control by looking at the schematic.
Help! Jerry

Is the idle control working?
Perhaps that has failed.

The engine speed will affect the frequency not the voltage.
The voltage is set by the voltage regulator circuit.
To troubleshoot this you will need some test equipment.
Many multi meters can read frequency which will help tell you what is going on.
