Okay, I have a bally S6000 that has the 23 error showing up. I have the leave in clear chips. I have replaced the optics and coin comparitor and these were both working about a week ago without issues. I am also having issues with the bill validator as well. I have also replaced the main-board also. Here is where the problem started. My bill validator was not cycling but the lights were on so I ordered a refurbished one from World wide gaming. I shut the machine down and replaced the complete validator and did a clear. I flipped the DS1 8 to on and proceeded with the clear. I let the machine go through what it had to shut the machine off and turned the DS8 into the off position closed the door, it cycled the reels and then went straight to the 23 error. Now I have tried all steps to get rid of this error. Opening and closing the door. Making sure the optics were cleaned. Making sure the harness was connected. Tried the reset button and nothing. Still shows the 23 error. I also replaced the harness between the back plain board and the validator. This was just supposed to be just a validator change but now has ended up a nightmare. Anyone have any ideas on what is going on or what I might have done wrong?? Help!!!!!!
