I followed this link http://www.metalworking.com/dropbox/...s/treadmot.txt
posted by Al on one of the treads. This was exactly what I was looking for since I have a very similar controller thats broken.
Problem is some of the resistor, capacitor and transistor values are missing and I don't know what to use.
Could someone that knows this circuit please help me out and fill in the missing information?
I would love to get a working version of this board.
