*WTB* IGT s2000 75427631 Reel IO Board

Hey Yall! Looking to by an IGT S2000 75427631 io board, because on boot up, reels spin backwards and buttons don’t work. the io for the buttons have been replaced already, so now moving on to the reels! thank you!!!

The reels do not interface through an io device. This is miss information that has been an issue on this site  for a long time. What you are discribing is usually caused by a faulty mpu or a major short on the senet lines. Inspect the harness that goes across the door hinge for damage if there is now damage remove the door and cabinet io cards as well as the bonus reel if your machine has one and boot the machine without them. If your reels still spin backwards most likely its the mpu if they spin normal one or multiple senet devices has a short on them.

Maybe he has a bent I/O pin in an I/O socket, and it's shorted out against another pin.

i’ve checked all pins, they’re all straight, nothing burnt, nothing looks fried

Have you pushed in or pulled out an I/O card or MPU with the power switch on?
Are you sure they work?

[momospinyo]

i’ve pulled both up cards out and machine still works. the only time the reels stop is when i remove reel 4

Since you won't answer the question I have about installing or removing components while the power switch is ON, I will assume both your I/O cards and MPU...are finished.
