I recently acquired an old Ives 1122 locomotive. When attempting to apply power the light came on but the motor was stone cold silent in both the forward and reverse directions (manual switch version).
I took it apart and think I have diagnosed it as a bad armature. When measuring the resistance between each of commutator plates it should be a short but I'm detecting an open between each pair. I was bit surprised they all were open.
A couple of questions:
1) I've read that their are folks out there that rebuild armatures. Are their any good ones that people recommend? I thought I heard about a guy on the east coast that did Ives motors.
2) The brushes have a little life left but are pretty worn. Does anyone out there sell replacements for these motors? I'm not entirely sure how they are mounted on the back of the brush plate. Are they pressed in?
Attached are a few images of the armature and brushes.
Thanks in advance for any assistance!
