I am trying to restore an old sears air compressor. All identifying information on the motor is gone. The power connection to the motor is gone. I would like a diagram showing the connections fo both 110 and 220 operation. The terminals are numbered 1,2,3,4 from the bottom to the top. There is a black wire on #2 and a white wire on #4. #1and #3 currently have nothing visable connected to them. any help would be appreciated.
