On KISS, the K target switch seem to be closed when the target has not closed the circuit. There is sufficient space between the contacts it appears. During idle the light is out of sync with the rest with erratic lighting going on/off. When I push the K target, it then syncs up with the ISS target lites.
During games an almost constant scoring occurs until I push the target...then it stops and the machine plays as normal. I've run the diagnostic test and it comes back with switch 20 being closed (K target), whether the target is pushed in or not.
Just when I think I understand a little something about how switches work, then this happens...,
