Speaking of buzz: The old cords weren't polarized. If you got a buzz, the cure was to unplug it, rotate the plug, and then plug it in the other way.
Today's extension cords are all polarized. So, if you are rewiring using an extension cord, how do you orient the wire so that the polarization is correct? There is a ridge molded into one wire of a two-prong cord, isn't there? Where does it connect to on the motor? Or the block, because the machine that I need a cord for is the pink Brother and only the poser cord from that motor/light receptacle to the wall is bad. The wires on the motor and light themselves are good.
