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..
