When I read the original post (noval idea)... it seemed to me that the generator was running... so the starter must be working... which would mean the gears are OK...
The OP says his microwave wouldn't run... not even the clock

Not necessarily. A working starter must engage the gears, crank over, then disengage. The discussion above was suggesting the third one may not be functioning and can affect the electrical output. This affected output could easily prevent "smart" electronic devices from operating, even the clock.
Just because something is running, it doesn't mean it's working.
Maybe I'm missing something, but AC is AC. It doesn't matter if hot and neutral is reversed or the ground is lifted, or both at the same time (to the MW, obviously dangerous). the microwave just doesn't care. Voltage isn't going to affect it either unless the voltage is probably 95V or less, or maybe higher than 135, but I doubt the clock won't work on over voltage since it's regulated.
What's left is frequency that several have mentioned. That clock locks accuracy to the 60Hz input to keep time, and may very well not display at all until it gets a reference. This is not a frequency locked generator, and the OP did mention that it speeds up.. Question is by how much and whats the resulting frequency? That's all that's left... There are DVM's that have frequency measurement, Amp Clamps, Plug-in AC monitors, etc. THAT's the next test.
Lets see... from what I'm reading... at least one of our responders writes the microwave won't work because of the gears in the running generator that has all of the 110V AC recepticles that it feeds functioning.
I give up...
Jim, please come back... explain all of this to me...

Read my post from a couple of pages back. I had the same conclusion until another member pointed out to me that some devices detect polarity on purpose and prevent operation (of everything, including a stupid little clock). This can be done with a simple detector between ground and neutral. It's also entirely possible that the microwave dectects a very specifc voltage range to prevent too high of a current demand from an under voltage condition. Yes this seems unlikely for a lowly little microwave but something's causing it to not work from a power source that runs other things ok (except the A/C unit--big clue there).
But again, the OP already confirmed the polarity is ok.

sleepy, you clearly refuse to comprehend, so there is no point in trying to explain it further.
It's all magic, okay?
Besides, it was highly unlikely to be the cause. The engine would chew up the starter in a few minutes, and it would not start the next time.
2002 Chevy 3500 DRW 8.1L/Allison
2000 Palomino B1500
...and the reason why I need a DRW to haul a Palomino:
2004 United 7x14 tandem axle enclosed toy trailer
2011 PJ 8x20 7-ton deckover equipment trailer
To clarify, the starter engages and disengages when it is suppose to. There is no problem with the starter.
I will call Johnny Walker RV see what they say.
