I have a gorgar here that has me stumped.
Every so often when I go to start a one player game it instead starts a two player game. This is an intermittent problem.
So far ive gone into the switch edge test to see if maybe the back stroke of the leaf switch was causing a second signal. That checked out ok. I cant get the switch to record a double hit.
I changed the diode on the switch thinking maybe some transient voltage was backfeeding somehow causing the double hit. That didnt help.
I then changed out the switch with a tested working switch and a new diode yet again. That seemed to fix it. But now after testing over 50 games its back.
Ive traced wires looking for breaks or any other visual clues that would point to the wiring. Everything looks good there.
I did a fatory reset to make sure it wasnt some setting.
Ive switched out boards to known working boards. Nothing changed.
At this point im pretty sure I can mark off board issues.
I feel I should be able to mark off the switch and diode.
Cant find an issue with the wiring.
