I have a Bally System S-Plus machine and I am having some issues with it. I just replaced the 3.6v battery because I received the error 12 code. Once the battery was replaced I received a 61 code, which then I pressed the self test button which game me the 61-1 code. However when I turned the reset key, the machine went back to the 61 code. Now when I press the self test button, 0 flashes in the coin deposited space and then the machine displays the 61 code again.
With this in mind, do I need IGT S+ Ram Clear & Set Denomination EPROM to resolve this problem, or what would be the next logical step to repair this issue?
