Since the problem is transitory, it’s going to take a long time to test. I got that plug in voltmeter from up thread. I also got a new multimeter for testing.
I tightened every single connection everywhere throughout the power system.
Immediately on startup of the generator for fine tuning, I saw 70 volts on the plug in meter as it cycled on and off about once a second.
No appliances at all were on except he battery charger, which is tiny and a default.
While it was cycling and not harming anything I checked some connections. Once the issue went away, I finally did what I had set out to do which was to adjust the generator speed to get perfect power. It was at 108 which is a little low. The frequency also was low. I moved it around but and ended up at 120v and 58.5Hz, under the load of the electric hot water heater. Good power. I couldn’t get exactly 60Hz without going above 120v so I stayed at those figures.
I haven’t seen the issue again yet, but have only used the microwave very briefly. It hasn’t been air conditioning weather in Florida lately. Ha ha.
I’ll update with new info in case anyone else has a problem like this.
FYI: I have a similar plug in meter and it always reads 105 when the gen is heavily loaded. I checked with a good meter and found that the voltage was really 110. Its a good idea to verify the meter is accurate.
