This might just be the lamest question I've ever posed, but I've never had this happen before. All of a sudden, my Bally Mystic won't let me add any credits. It boots up and goes into attract mode, but activating any of the coin switches does nothing. Dip switches have not been tampered with, but it's not possible to lock out all the credits anyway is it ? I tried to add credits with and without the coin lockout coil activated. Nothing has worked.
Check for a broken wire at one of the coin switches.

Looking for 1966 Bally Capersville, 1967 Bally The Wiggler, 1981 Stern Viper, 1986 Pinstar Gamatron, 1986 Williams Grand Lizard, 1991 Williams Bride of Pinbot, and a few others. Cash or some trades available. Could also repair a machine of yours +/-$ if needed, in exchange for one machine on my want list, non-working/unshopped welcome!
The wires seem fine. I assume since none of the coin switches work, you must mean a wire that runs from the coin door to the backbox ? I guess I need to check for continuity.

Took two minutes before dinner and reseated the coin door connector. Reseated J3 as well. Test mode works. Is that strange ? I'll do a continuity check after dinner. I don't have schematics handy. Is there a single wire that connects all of the coin door switches to the MPU ?

No, but there would likely be a single wire (ground) daisy chaining them together. Figure out where the ground comes in (probably yellow, red, or black, I bet) and make sure it's getting power.

Go into switch test mode and check your coin switches.
Then press the self test button until your credit display says "05" and add credits to the game with the start button. Exit self test mode, wait for the game to reset, press the start button to start a game and just play.

So what's up ?
wiggle the top right connector on the solenoid driver while someone trips the coindoor switches. I had a similar problem on 3 Sterns. Broken solder joints on header pins on the solenoid driver board.
