You guys have helped me before so I have complete confidence you will again..

My GT 917.273090 with a Kohler 22HP model CV22S no longer charges the battery,, Here;s what I have done so far according to troubleshooting manual:

AC on connector (disconnected from regulator )reads milli volts with engine running
Ohm'd the stator, across both White leads.. .2 Ohms.. manual says .02 ohms so I think I am probably OK there.

Ohm'd both white leads from stator to ground,, no short to ground: good

The stator is just a simple coil right? Not much to go wrong with them. Is there any diode's or components in the stator?
'
Thanks much

So I am trying to get the bolt out that holds the flywheel.. It's not reverse threads is it?. Whats the best way to hold the flywheel and apply max pressure on the bolt?

Ok I got the flywheel bolt loose,, Whats the best way to break loose the flywheel? There is a fair amount of rust on top of the crank shaft that comes up through the flywheel.. I will soak it good with PB Blaster over night and see what happens

No AC output from the stator means the stator or the magnets are no good. The stator is basically some wire coiled up, and should have next to no resistance. I don't know if there are any diodes in your particular stator, but I'd guess not. The stator is a pretty simple device, and it either works or it doesn't. Reasons for failure include opens, shorts, shorts to ground. Your 0.2Ω reading may just be your lead resistance on the meter. Short the leads together, and that's probably what you'll get for a reading. Reading 0.02Ω is nearly impossible except for laboratory quality meters. Your 0.2Ω reading doesn't seem bad, but your stator could still be shorted internally. Perhaps a close visual inspection might reveal some damage.

Well the flywheel is off, the stator has some rust and corrosion right where the wires come into it,, I cleaned it off, The magnets all seem good,, At least they attract metal anyway.. But no juice from the Stator,, I also found a dead short between the AC lug and DC lug on regulator. Now that can't be good!!! I used to do component level work so I am familiar with rectifiers,, So it looks like I will be buying a Stator and rectifier real soon..

Thanks to all

IF the stator doesn't put out 28 V AC minimum, it fails the test.

Just measured resistance between B+ lug and one of the AC lugs on my (fully functional) Kohler regulator...dead short. B+ to the other AC lug measures open. Measured in both directions and got the same results.
