Start Capacitor Wiring For 93274?

by Burt
(Allentown, Pa)

Bought a never used Central Pneumatic 60 gal air compressor model# 93274. It was missing the Start capacitor and Pressure switch. I have three wires coming out of the motor for the capacitor. 2 Blk and one red. I have no idea how to wire to the 4 prong capacitor. The pressure switch seems simple enough. 2 poles marked motor get white and black, green goes to ground. 2 poles marked line are for the power wired same way. I think. Can you help??? A/O Smith Century B813 motor.

That's a start/run cap motor.

Are there four separate terminals or 4 lugs on the cap?

Anyway, there should be a diagram inside the terminal cover to show the hookup.

If so, and you don't understand it, post pix of the cap and diagram, and we'll try to figure it out.
