Wurlitzer 2100 Help needed

I have a Wurlitzer 2100 that I have had for over thirty years. I have had it completely dissembled several times, and have worked on it many times. It has worked for me reliably all this time. This time I have been unable to get it operating again. It seems the whatever that energies the record changer motor is not doing its job. I can turn the motor by hand fully clockwise and fully counterclowise the record loads and unloads, but nothing happens as far as the motor energizing. The motor has just been rebuilt. New brushes bearing and rewound. I have not seen it run myself but believe it does. I can drop a quarter in it, select a song, the correct pin pops up then nothing. If I could just see the record changer motor run would be a great start. I am sorry I do not speak German. If I did I am sure I would get more answers, but please have mercy on me. I love this machine and will one day hear it sing again.

Hello Bill

With a single pin pops up, a "wobble plate" is activated and this wobbleplate action is detected by 4 or 5 electical contacts ( connected in series ). Are these contacts connected well to the wiring harness of teh mech ?
You find these contacts within the metal ring with the selection pins.
