See what the motor shop has to say bu that may have been the problem all along. With the motor running with one leg disconnected sounds like grounded winding. But it could also be a broken centrifugal switch. Roly

Update: I was removing the motor this morning to take it to the shop and was having an awful time getting the belts off. Long story short...I don't know how or when it happened, but the pulleys on the motor were pulled away about 3/4" from the motor, and they were rubbing on the steel rod that raises and lowers the blade. I tried to "persuade" them back in once I got the motor out, but they wouldn't budge.
I am now thinking that when it was at the motor shop the last time, they installed the pulleys there and I (or my neighbor) didn't notice it. That explains why the motor ran for a while before it quit. Since the motor is off, I've taken it to the shop to make sure there is no damage to it. Live and learn.....

Keep us updated as to what the shop has to say. Roly

I really enjoy reading these posts. First, I learn a lot, sometimes I can put that knowledge to use. Second, it goes to show that this place is full of great folks willing to help each other.
Please keep us posted as things progress. I'm curious as to the final outcome.
I no longer build museums but don't want to change my name. My new job is a lot less stressful. Life is much better.

Got the motor back from the shop today, and it appears the problem was a worn wire (inside the motor housing) that was rubbing against a screw. Either it has been wearing down over the last 25 years, or when the motor shop had it last time, they pinched it when they put it back together. Anyway, the motor is fixed, and as soon as my neighbor can give me a hand, I'll install it and give it a whirl!

That is why it ran with one leg disconnected. Let us know how it works when put back together. Roly

It's been interesting to follow this, I wouldn't have thought of a rubbed wire as being the problem. Glad you got it fixed.
I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.
