Trying to reset my Bally 5000+. I removed the MPU board and moved the bridge connector from J15 to J14. It then tells me to hold the 'pseudo coin button' down and turn machnie on, at which point the letters "SF" will appear. All good there. It then tells me to push the 'test' button once. However, there are two buttons on the front of the MPU board right next to each other. Does it matter which one I push? 

yes the one on the left is a reset and on the right is the test hope this helps

Awesome. That cleared all the codes. Am fully functional. Thanks! Now just need a new comparator. It seems a bit touchy. Doesn't take every coin, some come up "coin in reverse". Will try the sensitivity screw, but I think it is going bad.

What kind of comparitor does the 5000+ use?

It uses the CC-62D comparator. I checked coinmech.com and they show it was replaced with the MC-62. The new one looks like it is one piece, whereas the unit I have in the 5000+ has the coin accepter part, then a 6" cable running to the electronic box.

That's what I thought -- it's the same one that my Gamemaker uses.

The reverse coin error is caused by the opening at the bottom being too wide. If you check closely, there are two optics at the bottom of the comparitor and they are located almost completely to one side of the coin path. The internal metal guide that runs from a point just below the plastic sample coin holder to the bottom of the compirator has to be adjusted so that the coin just barely fits through the opening at the bottom. If there is more than about 1/32" of free play, the coin won't always pass those optics properly and you'll get the reverse coin error.

I think it was designed that way for security purposes, but IMHO, it's an earlier, flawed design when compared to the three separate, centered optics used below the CC16s.
