Hi all,
I recently found a SO that had many problems and didn't play at all. After finally getting credits to function, swing target to function, l&r rollover switches to work, spinner to work, bonus unit to step up, player 1&2 to function and 100 point relay to operate, phewww, it all works EXCEPT..... after getting the setup in place for an extra ball, roll over centre lane and extra relay pulls in. That ball continues to play fine and extra ball relay stays in. Next ball upon point score, the extra ball relay drops out but the ball index relay doesn't pull in. Can keep playing and scoring but when that ball drains the bonus doesn't score while stepping down and ball doesn't count up, resulting in same player playing again. Sometimes the next ball will do the same thing, other times ball index pulls in as normal. This happens with either 100 or 1000 point rollover switches ie sometimes it will work on either and I can't seem to find a consistent way to make this happen. Another thing which also makes sense but if you happen to get the ball through the spinner in the faulty mode, the machine tilts but doesn't do below.
If you don't tilt the free ball and drain it, the get extra ball to pull in again, operating the spinner resets the extra ball relay before it tilts from the rollover.
If I don't make an extra ball through a game, it all works as it should through to game over.
I have schematics and the manual but am kind of new to this but despite many hours spent on it, (or should I say weeks) I just cant work out why this is happening and think I may be looking at symptoms and not the cause. Frustrating but exciting. I keep thinking here it is, try something and no difference.
OK one other thing, the bonus unit steps up to 3000 not 1000 at start up. How can that happen?
Finger crossed someone can shed some light.
