Mesa Spinx1 and Minarik 32001A

Somewhere in the shallow folds of my brain is lost the idea that a circuit must be closed to work. Thank you andypugh.

Looking at the photo of the Minarik and the Spinx1 potentiometer terminals, in my previous post and the Minarik manual, a link to which I posted in a prior message, I believe I only need SPV and SP+ to turn the spindle unidirectionally (clockwise). I am only seeking to replace the physical pot at this time.

Any idea what led lighting colors I should see on the ENABLE, CW, AND SPEED leds I ought to see when an M03 and S have been entered through the MDI and the spindle is turning?
