I bought a watch makers lathe, but the wiring on the foot pedal speed control is ancient, dry and cracked with copper showing through. Easy rewire job I think so I bought some lamp cord, but now popping the cover the wiring is something I've not run across before. What appeared to simply be two sets of lamp cord one in from the outlet plug and one out to the motor side plug, turns out to be one cord.
Two wires going to the rheostat and two that are combined. The "center" two wires (of 4) are connected, in fact it appears they just cut the lamp cord in the center cut one side and pealed the wire back to attach to the rheostat leaving the other two intact.
Sorry for the crude drawing, but I think it will get the message across.
This seems simple enough but what my concern is whether or not this is actually as it appears, or if in fact maybe I'm missing something and the two "center wires" are not in fact connected as I think they are, maybe somewhere in there the two wires going to the rheostat are swapped to there is one from each side of the cord attached?
Other than direction the motor turns (then just reverse the wires if it doesn't match the directional switch on the motor) will it matter which side is which on the plug side.
Seems simple if I'm seeing things right but I don't want to let the smoke out of the motor.
