Sorry to resurrect an old thread but like someone else said keep all the problems in one thread might be a good thing.
I'm having an issue with an AC DC I picked up in a trade. It's an original wood back box one.
The cannon just does not fire when I hit the button. The button will work in switch test and I replaced the opto interrupter board. Switch 61 and 62 work correctly in Cannon test. The original opto interrupter for that came with the game would fire after 1 pass which I believe is incorrect. The new board will fire automatically after 2 passes like it's supposed to but does not seem to see the fire button being hit at all.
Any suggestions would be greatly appreciated!
