About a 40 year old Quincy two stage. Previous owner said it ran fine. Should be a capacitor start, capacitor run motor (written on a cover plate.) Please, how do I wire? Thanks-

Pat, I'm posting this on "electrical issues" in the hope an electrician sees this and responds.

I'm not qualified to give electrical advice.

Cheers,

You can only do this, Andrew, if the motor itself is wound for 120 & 240 VAC. If it isn't putting 240 into a 120 motor will fry it.

There should be a plate on the motor indicating the voltages. Or, search on the motor make and HP on line for details on that motor.

Cheers,

Bill
