Quick Question
Time to fire up the old sewing machine. The motor was always lethargic, so I thought I'd inspect it. It has a diode connecting both brushes on one side, and a capacitor(?) connecting the brushes on the other side. The blue thing is marked 0.02(M) 400, I'm assuming it's a cap. It's from the 1970's, so I'd feel better replacing it.
Can I replace it with a film cap or electrolytic? Cuz it is AC, but there's a diode. Last edited by MadMan; 06-09-2018 at 02:15 AM.
