Alright, I know everyone has seen the thread and read the reference to the Mephisto machine that I am having problems with.
I closed the other support ticket as the problem is not what was originally thought.

Stopping the reels is the issue.
The third button you hit, no matter which direction you stop them, you have to hit the button a couple times for the third reel to stop.
Also the right button sounds are really muted.

This is what I have done so far.

Removed and cleaned all three buttons.
Tried all buttons in each position. They work just fine as the first 2 button pushes, and the third one needs pushed a couple times.
No matter which button is plugged into the right socket it's sound is muted.
Ok the buttons themselves are not the issue.

I removed each cable, checked the cable for pinches or cuts. They are clean.
I checked to make sure all the pins in the sockets were good and not bent.
I plugged everything back in.

Below are two pics.
There are red Xs on each plug that I unplugged, I checked the cable attached to each one.

Thoughts?
