rest state.

      |  | When the ball rolls up the rail,
it pushes on the switch leaf, causing the switch to open,
 and the game shuts down.
 
 | 
    
      |  | To rule out the tilt switch
causing the problem, jump the terminals on
 the switch.  Run alligator test leads from the
 terminal with the green / yellow wire to the
 terminal with the orange / black wire.  This
 will cause the switch to be closed.
