I’ve seen this a few times. It could be a dead spot in the motor but usually it’s the contacts in the reversing relay. They have to be very clean and have enough pressure to physically push them when switched. I usually put an alligator clip lead in parallel for a test and see if it moves. The other issue with that set of contacts is that there is a small jumper between two of the terminals, make sure it’s not broken and making good contact. Hope this helps. Good luck, Mauro

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
