My machine has been playing great for a couple months, now all of the sudden, about every third game or so if you hit a rollover or drop target it will just keep ringing up the hundreds until you shut the game off.

Ok, I checked that... it's opening well.

It's really random, could be 3 or 5 or six games. Then all of the sudden in the middle of a game, hit a rollover or a drop target and it happens.

Hopefully I got this, more games will tell as it's an intermittent problem...I cleaned tightened and adjusted 2b and c and d relays....at first it got better but would show up again. The fact that it got better showed me this is the area of the problem...so I went back twice so far tweeking... thanks for helping...will post back in a few days when I know for sure the problem is resolved.

So I got to around twelve games in and it did it again, I gave the c and d a crimp... I'll try to play more than twelve games tonight and see...

Made it to 12 games and it happened again, going to take the 2b switch stack off the score motor...go over it really good...if that doesn't work, I wonder if a wire may be suspect. I'll try to jumper back to the relays and see if it goes away.

It's been a couple days and it's been playing great now so I'm going to mark this as resolved. Thank you so much for the help!
