Ok so i have the transformer and no dice still runs the same. Runs then shuts off then runs. I have the red wire on the pot to L(black) pole, Blue to W(white) and brown to speedpot these are the connector names. This goes from right to left on the pot with the contact facing front and the adjustment knob closer to me
