Thanks Alan. Can you confirm this is a Fortune 1? Do you have a tester in the shop?
I traced coin-switch leads through to the interface board (I will call it that until Im told differently). I also tested the switch NO/NC. I gently lifted the ribbon connector at block B, I found pin 11 was crushed instead of inserted and it has the appearance of having arched with pin 12. However, pin 11 (purple wire) does not attach to anything in the button panel. does that pin connect to something on the board which could have shorted?
After fixing the pin ( photo 1) the machine now acknowledges coin-in on the mechanical counter up top but does not count on screen, well it stops at 1 then errors:. (Photo 2)
