I bought a 36v 500w kit on Ebay and I think my controller went bad. I am having a hard time finding another controller. So I have two questions:

Where can I find a 36v 500w controller and are they universal? I knwo the voltage is not so I can't use a 48v controller but if I find a 36v 500w controller, will the plugs be the same and will it work the same?
