Hi Guys,

My Fireball EM has been working great, all features are working 100%... BUT... the ball count will not advance.

The Ball Index relay will pulse once points are scored, but doesn't remain on. If you tilt the ball, it will advance to the next player, but I can't get the Ball Index to stay pulled. I've checked and cleaned the contacts on this relay, ball count, tilt and lock, countless times and can't get the Ball Index relay to stay pulsed.

Any ideas, can't get anything to get the ball count to advance, other than through tilting, which will take it to game over if done on every ball... I've been through old posts and can't find the answer to this one!

Please any help or ideas would be appreciated!

Thanks Howard & Rolf! I have tried bridging these contacts on the diagram and still can't get the Ball Index Relay to stay locked, so it won't advance the ball counter. The only way to advance is by tilting. All the 3 balls count correctly for multi-ball in 1, 2 or 3 ball, but no scenario other than tilt will advance to the next ball count...

I have removed the play field several times completely, and the Jones-Plugs seem OK, but I'll double-check for continuity to the Payer Unit in the backbox.

This really has me stumped as all other features are working 100%, and this came up suddenly as this machine has been working great for years, I imagine there is a dirty or out of adjustment contact SOMEWHERE, but where?

The Payer Unit was the culprit! I removed the Player Unit from the backbox and cleaned and adjusted the contacts. There was one out of adjustment, should be always closed and had a slight gap. That sorted the issue, playing 100% again.

Thanks for your help, I spent all the time checking and cleaning contacts in the cabinet, and the problem turned out to be simple, but in the backbox.

Keep well, Red
