I am working on a Bally Bow and Arrow em machine and must have created this problem while fixing another.

Once you get 10,000 bonus points lit, the Extra Ball Center Target lites up, and/or one of the Outer Roll Overs are lit as Special When Lit. However, when you hit any of these while they are lit, you just get the 1,000 points and no extra ball. I do have it set for extra ball instead of free game.

I have been concentrating on H-G 8-9 on the Schematic.

The schematic is here: https://www.ipdb.org/files/362/Bally_1975_Bow_and_Arrow_Schematic_Diagram_continuous.pdf

Anybody have an idea where (else) I should focus my attention?

Thank you in advance for any assistance you can provide.

Thanks @studentprince, the things look ok to me. I’m not 100% sure about the Bonus Limit (not exactly sure which one it is), but I’m also having problems with the Bonus score when the ball drains. It does not award the last 1,000 pts (2,000 with Double Bonus). I wonder if these things have anything to do with each other.
I added pictures of what I believe is the Bonus Limit switch on the Bonus Score Unit.
One each at 0, 1,000 and 10,000 points.

Thank you for your help.

I took a closer look at the Tilt Relay, and sure enough, there were a couple of NC switches not making contact. Re-adjusted them and the Extra Ball works, however, an Extra Ball is awarded when the Center Target is hit without the Extra Ball When Lit light (less than 10,000 bonus).
I’ll try to figure that out now.

Looks like the Extra Ball is working, not sure why it was awarding one when the Center Target was hit when the Extra Ball When Lit IS NOT LIT, it’s not doing it now.

Thanks for your help @studentprince!

I think it is more of a mechanical problem. I did change the springs and it seems to be awarding the whole amount now.

Thank you for your help with my machine @studentprince. You really helped me a lot.
