At our museum, we recently purchased a used 2014 WOZ. We are having
all sorts of switch matrix issues. Any ideas of where to start
troubleshooting? Below is a quote from one of our tech:
"There are lots of odd switch matrix issues in this game. Closing the
upper slingshot switches on either slingshot will generate phantom
switch closure on the BALL standup targets and TOTO rollovers.
Similarly, pressing on the castle doors will generate phantom closures
on the monkey and winged standup targets. Wiggling the wire harness
under the castle will also cause a bunch of phantom switch closures.
Raising the playfield causes the VUK behind the crystal ball to work
correctly, lowering the playfield and tapping it gently will cause the
VUK to stop working and generates a bunch of odd switch closures.
Last, there is some issues with ball locking. Occasionally, locking a
ball will result in the usual ball lock graphics, but no ball is
placed in the shooter lane."
