I have the Voltmaster 12/15 and I have not been entirely happy with it. My problems have been:
1) To keep the Hz at 60, voltage is always a little to high, usually 125-130, 250-260.
2) My tractor governor doesn't seem to sense the increase in load unless it is significant and so HZ and voltage drop a little more than desired. (Probaby not the generator's fault)
3) After a couple of years, the hole plugs on the side of the generator gear reduction box started to leak. Every year since, it seems to get worse.
That voltage is too high. I took a quick look at the on-line manual, and the manufacturer claims voltage regulation should hold +- 1-1/2% so you shouldn't see over 121.8 volts. It looks like some of the models have an adjustable regulator with a pot adjustment, I would check and see if yours is one of the adjustable models. If not, I would contact Voltmaster and tell them of your problem.
