Quoted from alistaircg:
I have a problem that I can not figure out, please could somebody help ?
WCS94 has 4 balls. When locking balls , 1st ball locka successful 2nd balls does not lock. When the player looses the 2nd ball, the machine searches for a ball (know that there is a ball missing, this ball is in lock mode) . After searching for the ball for a couple of seconds, it then decides to release the ball (1st ball) that was locked
When going through test mode in the program, all switches and sensors indicate as working. The machine does not display any faulty switches
Hmmm... that kinda screams bad trough opto to me.
