One more question. I have everything apart on the wiring now. Whoever played with it last had twisted on a steel colored wire to wrap around the posts. Is there any reason I can't strip off some more covering and use the copper like I do with a lamp? The addition of the other wire just made for more bulk. No wonder something got crossed. I will be wiring the power cord to pins 1 and 3 and the foot pedal to 1 and 2. That's how the generic diagram and 221 diagram show. I have no light wires to deal with, thank goodness. Wish me luck and thank you for your help.
