Quoted from marcburn:

the reset sequence does not complete and the motor continues to run. I’ve traced it down to two problems where my question really lies. The huge coil that pulls in a reset bar to reset the control relays is not firing.

If (1) the score reels reset to zero and (2) the DS Reset relay on the control bank trips,

Inspect and diagnose this circuit with Alligator clip jumper wires
