bally 5000 issues

[BALLIGATOR]

Hi,


Today's mission was to test my spare Bally 5000 plus spare boards.


I tested them on a machine working perfectly. I mean, you insert coins and you can play games.


2 of the boards I tested "semi"worked as the machine does not accept coins when these boards are inside.


That seems obvious to me there is smothing wrong somewhere with these boards. Would anyone know where on a Bally 5000 board it has got to do with the coin acceptance?


I hope some expert will be able to help me.


Thank you very much.

Try it in input test menu.
Maybe input ic bad on IO board or not enable coin validator or comparitor.
On door is small switch can enable or disable coin validator.
