Generator volts and Hz way off? December 27, 2018, 08:00:30 pm I tested an outlet in the RV with some lights on.Hz - 64-65.5 HzVolts - 130-133 VACVolts at automatic choke lead on carburetor - 30.3 VAC. I think this is way off.Is this a generator control board problem?
Re: Generator volts and Hz way off? Reply #1 – December 27, 2018, 08:35:26 pm It isn't way off. Dial the governor down to 63hz and see what you get. I think the spec is 127 volts at 63hz unloaded.

I can't tell you which screw that is. It should be pointed out in the manual. Perhaps someone else knows which one it is. 1 Likes
