Weird, my 3/4hp 8 inch Craftsman grinder I bought used 30 years ago died yesterday. It uses an obsolete starting relay that I tried to repair by cleaning the contacts, but it still won't go unless I give the wheels a good spin to get it moving. I hate to give up on it, but maybe it's time for a newer one after I get tired of spin starting it.
The capacitor has crapped out on it. That relay runs power thru the capacitor for starting, then takes it out of the circuit. Is there a cylinder on the side of the motor or maybe under the base? That's the start capacitor.
