You have an early version of the 5000 series. First 2 things to check are the power supply and the battery on the MPU board. The power supply is mounted on the back bottom right corner of the cabinet. It’s usually the low voltage section of the board that has failed, but since these power supplies are so problematic, you’re better off finding a replacement with the required outputs. Badbaud has contributed many posts to this topic. If the MPU has acid damage, it’s going to take some work to repair. Once those 2 items are addressed, you can begin troubleshooting, but unless you can work on the boards yourself, sending off to K-LAR is a really good option. Slotmachinerepair.com They will either repair it our let you know if it can’t. If the game chip is corrupt, then you have a boat anchor. Bally didn’t use the best materials when making these, so considering their age, it’s best to go through them replacing all pin headers, and replace all chip sockets with new double wipes. You’ll also need the keypad to setup the machine after it’s working. Good Luck!

How do i get in touch with K-Lar and how much do you think it would cost to fix?

Thanks

Thanks I appreciate the info, I bought the software on ebay and it cam incomplete with just a copy the game card, the seller is trying to say it's a non dongle version and I am running the wrong os. Looks like I wasted my money...
Thanks

Hi there................

All BB3 games require dongles except perhaps that Illinois multigame one.   Ferris Bueller uses OS family 18.01 or higher within the OS 18 family.

Hope that helps..
