[ATTACH=CONFIG]340343[/ATTACH][ATTACH=CONFIG]340344[/ATTACH]Here are two pictures. Sorry, the one is blurry. The terminals are numbered 1, 2 and 3. 1 and 3 each have one wire that leads to the wall plug as a normal two wire cord. terminal 2 is the one with the two wires on it that lead to a normal two wire cord to the foot controller. They are the two wires sticking up in the clear picture. The burned spot in the cord was not inside the plug. All four wires have way more copper showing than I am comfortable with. Very strange. I've always thought it was one wire to one pin. Period.
