Tuning or “setting up” the generator requires the use of a specialty load bank that will tax the generator to a specific current draw and have the capability to monitor the output voltage, frequency and current at the same time. —Mike C., Newbury Park, CA . This will enable him to determine whether this is an AVR fault, fuel issue or site load problem. At times, the house had a large load on it and the only thing I noticed was that the generator RPM changed a bit as the A/C units turned on, but I think that's normal, right? 877-287-1179.
