High frequency on generator
I just changed my governor control board on my Kohler 5.5 KCM21 genset because the genset was running at max throttle. The new board fixed that problem and the genset engines idles down as it should. ...

electronic Automatic voltage regulation on the field will control the voltage even if the frequency is off
High Freq does not mean high voltage when you have AVRGjac wrote:SCVJeff wrote:That is what I have always thought. But I checked it with two different meters and both read 120 vac. Also same two meters also read 120 vac when plugged into shore power and 60 hz on the meter. I tried readjusting the carb both main and idle jets but rpm stayed the same. Makes sense it rpm is high the voltage would be high but it is not.
If the frequency is high, so is the voltage. A frequency error won't fool a charger into excess output. Find a real meter that can read a wider frequency band and see what's really going on. We use those Kohlers in news vans and they simply die of old age.
