The condensor fan blade was barely turning. They don't work very well.
"Real Blades" turn so fast it will scare the tar out of you. Not something most people hold in hand more than once in good wind.

Like Norm said, need to make sure the fan blade hub doesn't come loose and fall off.
I use a few of the HF drill stops (50 cent coupon sometimes). May be enough room on the factory shaft? LOL.

Jerry,
Some of the ECM star / delta / JR numbers never made much sense to me.
(1/2HP, 500 RPM, Star or Jerry, 3.4A)
Maybe Jerry Rigged with a fat motor-run cap in series with each phase before the rectifiers would help?
F&P has about the same issues? In case you missed it,

As far as the hub, it's pretty beefy steel. Trane makes pretty good stuff compared to other brands. It also has two set screws. I don't know if you guys know this trick, but when you tighten a set screw, loosen it and do it again and it'll set even tighter. I can always put a tack weld on the shaft to the hub if needed and grind it off if needed for service.

Just need to get this wiring figured out so I can go forward.
