Hello, I have a Bally Black and White 5500 that was not working when I got it. It is a earlier version using the Jumper plug to do a saferam clear not chips. I replaced the battery and did a Complete SafeRam Clear. I ran thru Diagnostic Test 1,2,4,5,6,7,8,9,and 10 with no fault codes. Test 11 has all Game Optioning the number that is in the ( ). When I run Test 3 I put quarters thru the comparitor and 09 appears in the Credit Diplay and a port status 1. I know the comparitor works, meaning I can take a mix of coins and feed them thru and only the quarters go to the hopper and the rest go to the pay out tray.
The problem is no credits will register when I insert quarters.
Also not sure if this is part of the same problem or different but the Bill Validater does not work. It will not even try to take a bill in and validate it. The Validater is a DBV-200 which I believe is not original to this machine.
Any Help with this is appreciated, Thanks
