I am restoring a jukebox from 1953 (AMI E-120). Everything is going fine except the main drive motor, an A/C induction motor, cannot start under the load of the platter. It starts fine when the belts are off, but under full load, it won't start. And once I start it with my hand, it runs fine.
That makes for a pretty worthless jukebox.
(The pics above are of another one that looks like mine)
I've taken the motor apart, and cleaned and oiled everything. It looks spotless, but it still doesn't have the guts to start the player.
What steps would you do next? Have the magnets gotten weak? Or do the coils need re-wiring?
Thank you in advance.
