Low voltage out of Genset
Most of these generators either run at 1800 or 3600rpm, check which yours is
close to. If you are lower than either of these numbers, then you have to adjust. Bill 84FC35SB Terrace, B.C. Curt Sprenger I'm not an expert but found this on the Internet. For an oscillating or varying current, frequency is the number of complete cycles per second in alternating current direction. The standard unit of frequency is the hertz, abbreviated Hz. If a current completes one cycle per second, then the frequency is 1 Hz; 60 cycles per second equals 60 Hz (the standard alternating-current utility frequency in the United States). I recall the Onan guy adjusting rpms on our previous gen. set to get the frequency to 60 and to increase voltage. Sounds to me you are on the right track. If you can, turn up the rpms and watch for voltage increase. Good luck. Please keep us posted. Curt Sprenger 1987 PT38, Anaheim Hills, Calif. Alan wrote: > My 87FC35 has a 8.0 kW genset.
