I have a Williams Jive Time with a peculiar problem which has me stumped despite many hours of investigation and head scratching – I’m hoping someone out there might be able to give me inspiration to find what is wrong.
I’m sorry, it needs a long explanation.
The issue occurs when I’m awarded bonus countdown from a spin, and depends on the position on the bonus ladder.
What should happen is that the bonus should count to zero, the ball eject from the spin hole, and one bonus added back to the ladder.
That works correctly provided the bonus is on 5 or 6K. (only) (or beyond the bonus limit – see comment and video in 2 at the end of this post)
If the bonus is 7K or above the bonus counts down correctly but the ball is not ejected, instead the game awards another spin and scores the result of that spin
If the bonus is 1 to 4K the sequence operates correctly (ie the bonus counts to zero, the ball ejects from the spin hole, and one bonus is added back to the ladder), however the motor then continues running in an indefinite loop – the bonus of one K is counted again, the eject kicker fires, and one K bonus added back to the ladder – repeat ad infinitum until the game is turned off
I can see that for 1 – 4K bonus the eject relay is never released from being locked in, and it seems that is what keeps the motor running. For 5K bonus and above the eject relay does release.
I also have found that if I insert an insulating strip between the contacts on the bonus relay which lock in the eject relay whilst the game is in the endless loop then the eject relay gets released correctly and the loop stops. However I can see that those contacts are being opened correctly by the bonus relay itself
My reading of the schematic (extract in photo) is that
• The eject relay is energised initially from the spin relay
• It remains locked in through its own lockin switch and either of:
o An NC switch on each of a series of relays, each of which is one of the spin results
o An NC switch at motor 4C
So, I would expect the eject relay to be energised by the spin relay, and then released by whichever relay is energised as a result of the spin, unless the motor switch happened to be closed at the time.
The only logical thing I can think of for the problem I’m seeing is that, for the bonus relay, the motor switch locking in the eject relay is closing at the exact moment the switch on the bonus relay locking in the eject relay is opening.
That’s as far as I’ve got, and my brain is exploding!
• Does that seem a likely explanation?
• If it is what should I do about it?
• Why should I get three different results depending on the position on the bonus ladder?
Three other things which are relevant
1. If the award is double bonus the position is different – on 1K bonus it works correctly – scores 2K and ejects ball, on every other bonus level I get the same result as seen on single bonus of 7k plus, ie bonus counts down correctly but the ball is not ejected, instead the game awards another spin and scores the result of that spin
2. Although the maximum on the bonus ladder is 10, the game will continue adding bonus (which can be scored) up to 30. When 30 is reached there is an audible click and the game will no longer try to add bonus. For bonus levels 11K to 16K the machine behaves correctly (video here
3. The game has not behaved correctly since I got it so I wonder if some part could have been fitted incorrectly? I’ve compared the bonus unit disc to the picture in the manual and it appears to be the correct unit and correspond in appearance and orientation.
If anyone can help me solve this I shall be eternally grateful, and will make an additional donation to Pinside by way of a thanks offering!
