1 WPC Specific Issues
2 Game-Specific Issues
2.1 Path of Adventure Switch shorts causing extra balls to be served
The front right switch on the path of adventure gets hit underneath by balls hopping around the "Mode Start" hole. This shorts the wires/diode/switch lugs. This switch is on the same row or column as the ball jam opto. This is the last opto a ball passes as it is served to the shooter lane. If you are getting extra balls kicked up to the shooter lane, that front right switch is a good place to start.
2.2 Balls Continuously Served to the Shooter Lane
A failure certain to cause this behavior involves the "Ball Jam Opto", which is the last opto a ball passes as it's served from the trough to the shooter lane. If either the sending or receiving opto in the pair fails to work, the game will sense a jammed ball and continuously serve balls to the shooter lane. Sometimes the opto(s) fail outright. Sometimes the cause is a fractured solder joint or the OEM 270 ohm 1 Watt resistor on the sending side opto board.
