Question about Craftsman 6" Bench Grinder with Lamp
With relation to my bench grinder 319.19062. The old capacitor I am replacing had one red, and one black wire. I noted where each was connected to. The replacement capacitor has two GREY wires coming out. How do I know which wire goes where? My question relates more specifically to the new capacitor. The part number for the new capacitor is #3AA03301 Connecting the red wire and the black wire is self explanatory. Having two grey wires gives no indication of which wire goes to where the red and black wires were connected previously.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

I know this is an old post, but maybe it will help others looking for information.
I have the Craftsman 1/3-HP grinder models: 397.19580 & 397.19581.
They are Split-Phase single voltage (115 V), and use a Klixon start-up current style relay - 2CR14-224.
The relay is normally open. When the large starting current in the main/run winding circuit is sensed by the the relay coil (term 3 & 4) which is in series with the main winding, the relay contacts close (term 2 & 4).
The one end of the start-up winding is connected to the main coil's BLK wire in the coil pack.
When the relay contacts close the start-up winding is energized. The start-up coil is used to provide a boost to over-come the resting inertia of the rotor.
Once the rotor reaches between 65% - 75% of operating speed, the current through the main winding circuit is reduced to the point that the relay coil cannot over come the return-springs force, acting on the relay contact arm. With the contacts open, the start-up winding is no longer energized.
This should take about 2-3 seconds, if the relay malfunctions, the high current through the start-up windings (thin wires) may be damaged.
Here is a diagram I have made.
Klixon 2CR relays are no longer available.
