Just back to working on my Bank-A-Ball, I replaced a burnt out score motor and now have the game resetting and playing but not scoring on rollovers.
The pop bumpers score 1s when not lit and 10s when lit - so that is good.
Slingshots score 1's - also good.
Rollovers score nothing, they do bring the correct ball down on the backglass and the C relay operates. But no score.
When the C relay operates nothing else happens, the score motor does not run and I can't hear or see any other relay pull in.
I have a suspicion it has something to do with the P (series) relay, but that's only a guess because if I hold the P and C relays in I get scoring, but the P relay does not pull in with the rollovers, should it?
I have a schematic but I can't quite figure out what energises the P relay, it looks like it has something to do with the 1 to 15 coils or the 3 to 5 ball select, but neither of these make sense to me.
The game did previously work for me. Another suspicion I have is that there is a problem on the score motor switches - maybe I bumped something when changing the motor out, but I have looked carefully and can't see a problem there.
I hope someone can help me.
