Machineboy would be a good person to ask. I am not certain but i think the polarity is crossed on the stock cable and i believe the machine has counter rotation protection so it won't run if the polarity is crossed. It would be an easy way to insure that you have to buy a cable from the manufacture. Take a clip cord with positive negative color coding and touch the different areas of the plug in the back of the machine. If it runs then you know how you have to wire a new cable.
