Just started poking around this old girl and had no voltage at E1. Put in new brushes and repaired broken wire to resistor in the exciter end bell and the exciter came back to life at around 125 Vdc
Motor contactors pull in now but spindle won’t go. Small arc from DB contactors when engaging fwd or rev contactors with drum switch.
No 230 Vdc coming from generator so spindle won’t go.
I have not looked at the generator brushes yet but that is on my list for tomorrow once the grandkids go home. Also plan to check out the generator field and armature while I’m at it tomorrow. The generator commutator looks good as does the motor so I dont suspect the brushes but I have them on hand just in case. Any thoughts?
