This video shows some hints why the Stern Pinball Rush Premium/LE motor board issue could appear. The motor board is for controlling the servo motors for the time machine ramp and the clock.

Maybe possible issues for a burned down motor board (node board 10):
- broken or short-circuited cables of clock or ramp servo motor
- bad connectors additionally with bumper vibrations
(lose contact swing by impulse - dirac delta function)
- warmed up clock housing that touches the motor pulley
- warmed up washer between ramp motor and pulley

Combination of changes to reduce the failure of node 10:
- motors with good cables (shrink tube is better than cable ties)
- new or good connectors (life time of connectors - video #0041)
- decoupled/swimming node board 10
- decoupled power and motor connectors from vibrations
- remove ferrite cores from tortured connectors to release crimps

There are some additional pictures in my Blog. Description in German.
