    Quoted from GoldenBear:

    does anyone have any ideas on what to look at.

    It may be that a set of switches in the "Extra Shot Reset" Relay may slightly be touching
    when it suppose to be open. So you'll want to check the contact gaps in that relay.
    But most likely, I have a feeling that once in a while the "Score Control" Relay isn't energizing
    when it should be. If it doesn't energize, it will step up to the next player.
    Is this a ball of shuffle bowler? Either way, with the coffin open, if you can manually touch one
    of the sets of the last roll over switches together while keeping an eye on the Score Control Relay
    and when the problem occurs, see if it's because the Score Control Relay is not energizing, and second
    thought, as far as that goes, it could be that a set of open switches in the Score Control Relay is almost
    slightly touching when it's suppose to be open and from vibrations once in a while they touch just
    enough to make contact. So first checking the contact gaps in that relay would be a good idea..
    Let us know what you find. We'll get her fixed..

    No problem at all. I know what it's like to have a problem..
    I don't think its a mechanical problem in the stepper because the
    stepper is stepping up, it just that the step up coil is energizing even
    when it's not suppose to be. Has to be electrical.
    I'm thinking the Score Control Relay isn't energizing 100% of the
    time when it suppose to..
    I don't have a Team Bowler schematic, but do have a Bowling Alley
    schematic which should be close to the same minus the extra score
    reels that total the teams score. I can have a copy made for $10.00
    plus shipping if you like. Shipping might be 3 or 4 bucks. I'm on the
    east coast. It's a $30,000 copier at a Surveying Co. Comes out clear..

    Yup, same as pinball. Those switch stack screws need to be tightened before adjusting.
    Minus the ball lift and team scores, 1955 Regulation shuffle and 1956 Handicap shuffle
    schematics are primarily be the same, along with the small ball bowler Bowling Alley.
    Also an 1957/58 United big ball bowler schematics would do the trick..
    Yea, those vintage ball bowlers are pretty cool. I have a few. Not as much engineering,
    but those United Target Shuffles are alright to play also.
