Has the motor been removed at some point?
If so, it is possible the two windings have mistakenly been swapped. This will result in poor torque and stalling.
Since you covered the issues of start/run capacitors and add section contacts, this leaves the motor itself.

This was from an exchange I had with the late Ron Rich:
I'm still looking for someone who could measure the resistance of the windings on a Bodine KCI-42 motor for me.? Two measurements - one between the GREEN and YELLOW wires and another between the RED and BLUE would tell me what I need to know.
I'd really appreciate help on this, thanks!
----Ron, you have a good motor, I have 100.3 (GREEN and YELLOW) & 259 RED and BLUE on a known good KCI-42 (plastic wires).
Rob, those are the measurements I found in my notes as well.

You will need to unplug the mech from the control center

Seeburg KD has been gone thru, boards rebuilt, mech removed, cleaned, lubed, all switches cleaned and checked with meter. When I make a selection, the motor will not start until I manually turn the coupling a few revolutions. Then it selects and plays just fine. "O" contacts are good and I installed a new motor cap with the same results. But here's the kicker - if I turn the motor in the "wrong" direction, it will start rotating that direction and play normally, even with the reversing switch flipped the other direction. While scanning, I can flip the reversing switch but it will not change direction. It will do this in either direction. Bizarre... The only way it changes direction is when it bangs into the hard stop and the motor temporarily stalls. I will try another motor tonight, just wondering if anyone has seen this before. _______________________________________________ Jukebox-list mailing list -- jukebox-list@lists.netlojix.com To unsubscribe send an email to jukebox-list-leave@lists.netlojix.com %(web_page_url)slistinfo%(cgiext)s/%(_internal_name)s Searchable Archives: http://jukebox.markmail.org/
