The switches on the slingshots have not worked since I've had the machine. I put a new connector on J3 of the solenoid driver board because it was hacked, and now more of the switches are not being recognized. Switches 1,8,28,29,31,32,34,35, and 36 are not being recognized. This includes the outhole switch, and a number of stand-up target switches. I've tried the working Alltek MPU, SDB, and lamp driver boards from my Flash Gordon, and still the same switches aren't recognized. Any ideas on where I should be looking? I'm getting confused. Is J3 on the solenoid board related to switches at all? All the solenoids test good on the solenoid test. Thanks in advance for any help.
