I never claimed to be a full time Lincoln or car mechanic. I do it on the side and work on a lot of different types. I can be wrong so whoop de do. The machines i work on at work are CNC machines that cost up to a million $. I am not asking how to make a check pin board for a fanuc alpha spindle drive so i can check the BZI output signals with my scope. I figured asking people that work on them regularly would be faster and easier. Thank you LS4me for the pict. That does bring back memories of a nightmare job from hell.lol
