The speed potentiometer on my mini mill broke and when I removed it for replacement I didn't make note of which wires went where. I hooked them up as best I could and now NOTHING - mill won't work. Does anyone have a schematic or any other help so I can get my mill running again. There are two wires labelled K1 and K2 (black wires) and three wires labelled P1, P2, and P3 (blue). I am worried that when I connected them I might hove damaged the controller (hope not!).
