I have an old Delta bench grinder that no longer spins when started. I can get it up to spin by hand and then the motor takes over. I believe its the starter capacitor but I keep seeing people talk about the, "centrifugal switch," how do I test that? Or is there a way to test the cap, I hate wasting money so I would like to get it right the first time. The starter cap is marked 10uf 250v is there anyone able to direct me to one I'd greatly appreciate it, I found a few but I believe I will break the rules if I link them.
