My grinder does not have, or use a capacitor. It uses a Klixon 4CR starting relay in series with the start/run windings. It also needs to be an exact match for the motor size too. I don't know if I want to go to the trouble to find a pricy replacement and have it still not work.
Pulled it back apart today to troubleshoot with my meter. Good thing I didn't buy a relay. The start winding was open. Guess I'll spin start it and start shopping for another good used one, instead of a cheap new one. I really like the 3/4hp 8 inch size. Not too big, not too small.
I just came up with an easy way to spin start it. Took a 3 in wire wheel in my cordless drill and held it up to the wire wheel on the grinder to bring it up to starting speed, and flip the switch and away it goes.
