Hey guys, I have a head scratcher. We have an old Bridgeport with a 6f power feed on it (not sure A B or C). A little while ago it stopped working in either direction but with a light rap with the hammer it'd live for a little bit longer. It is now fully dead. So I pulled it apart and cleaned out the armature and replaced the brushes. Now it only works in one direction. I've checked the micros and they both check out fine. Double triple checked my wiring against the diagrams floating around. Nothing seemed too torn up inside just dirty. What's my next step?
