Hello-

I have lost the +15v signal on my 1982 Fanuc 6M-B DC spindle board (model A20B-0008-0378/02-08D).

I am seeking to purchase manuals or drawings to help me trouble shoot. I've already contacted machinerymanuals.com, but they don't have what I need.

Any suggestions about the manuals are appreciated! Or if you have ever lost the +15v signal(s) and the ability to command your spindle to turn, please let me know what to look for on the board!

Thanks,

TFGC
