Unfortunately quite a few of the relay name tags are missing .Which makes it a tricky one to fix, But the rollovers trigger the A + B relays , works fine if only one is tripped and adds one bonus like it should , Will work like that on either A or B relays. But when the 2nd relay trips Either A or B game Bonus unit just keeps adding . I can get it to stop by triggering several relays. I am thinking a sequence relay . game is not at my place and schematics are in the machine .   I have looked around for a manual 99% sure they made one for this game, Will try PBR  , will let you know the outcome ... Oh and yes there is a scoring problem,  mainly the targets . But i think it will linked to the other problem will the game .
