I have a Commercial Generator Set Standard DieselTM Series SD 20 kW 60 hz , Model 20HDKAW-2008A, 60 Hz, 120/240 Voltage

It is in my ice cream truck and the voltage is a bit high and is causing some problems with my soft serve machine. My machine tech checked the voltage and said I should lower a bit as it is producing too may volts for the machine.

There is no visible way to lower voltage that I can see. Does anyone know how I would go about this? Would it be as easy a reducing the RPMs?

RPM must always remain locked and fixed at 1800 RPM.

What voltage is it making and what is the machine expecting?
