I tested the capacitor like mchaury suggested above – put ohm meter across contacts and let it settle, then switched the leads and it jumped up then settled again – not OL, but a small number. I don’t know what scale I was on, but still going off the fact that the capacitor shows no signs of damage I still assume it’s good.

So I go on to check the contact points like Grizzly describes in the email. So I start at the fan end of the motor and remove the cover:

Then the fan:

DSC_3095

and what I assume is the metal dust cover they refer to:
DSC_3096

The I look for the centrifugal switch mounted onto the motor shaft, but all I see is this bearing:

And all of these burnt wires:

I never found the centrifugal switch or the setscrew, but after seeing the wiring, I’m assuming the motor is fried. This may be my first time being ripped on a craigs list purchase, but I don’t know if the seller did this or I did. After all I tested it at his house, rann a few boards through it at my house before it bit the dust. I was in the middle of jointing a very small cut off the edge of a 1.75” wide pine board when it died, so I’m pretty certain I didn’t overstress it.

I’m sending the pics to Grizzly and see what the ask for a new motor.
