One problem with a lot of the repro accessories is dried grease. These mechanisms sit around for years and end up with grease that becomes like glue. Since you have voltage to the motor, it would be nice to know if it is drawing any current. I use bench D.C. supplies to power the motors bypassing the internal supplies in this situation. (Note You need to disconnect at least one motor lead to prohibit power from being applied to the internal electronics). Since the supplies have both voltage and current meters I can make a judgement as to what is going on. If possible. lift one of the motor leads and insert an ammeter in the circuit. If current is flowing, the mechanism is probably stuck. Be careful not to let the supply on for any extended period as you can damage the electronics supplying power to the motor. If this is the case, you will need to disassemble the mechanism and clean it thoroughly. Then lubricate with fresh lubricant. I hope this helps.
