friend has a 21-820 power feed on a rockwell mill.
Controls and motor were fried
Motor has been rebuilt, but now issue is controls.
it appears there may have been an updated circuit board 438-01-307-0100 (we think that is correct from the schematics we have found
but - can't find source.
either source of the updated circuit board or an original wiring diagram are what we are needing help in finding
