Yes, this! If you are unsure which pin, post a pic of the unit looking straight down the shaft on the switch side. (Opposite of the white reel side). We can guide you from there.

Ok. The metal pin on the gear that is pushing on the switch stack looks like the max credit pin. The other pin is molded into the gear itself, right? I don't have a Bally credit unit in front of me and it would be worth waiting for someone else to confirm this, but here goes.

Notice all the holes in the gear around the outside edge. Look closely at those holes and I bet you will find that they are threaded. If so, I bet you can unscrew the metal pin and move it to one of those holes. Each hole is going to give you a different max credit. Let us know how you come out.

I saw that one a while back. It inspired me to get to work on my C37 Schematic. Wish I could share it when I am done. I will show a clip of it when It is further along. Right now, I am about 1/4 finished.

You will notice a lot of your targets are bent back. This happens. Bending them forward may help for a while but all you are doing is further weakening the metal support bracket for the target. If balls are getting airborne, you most likely have targets that are bent back. There are foam "dampers" that can be installed behind the target faces to reduce the blow to the brackets. PBR sells new target brackets and modified "reinforced" ones for some games. I agree with the others. Don't glue anything on top of the plastic. Instead, find a way to stop the airballs! A lot worse things than a stuck ball will happen too. That center plastic is at risk of being broken if a ball is flying around like that.

It probably has been covered, but a good coat of wax and brand new balls can do wonders for a game. It speeds things up and at the same time reduces air balls.

In case you haven't noticed yet, if you metion that you have "seen something" "somewhere" "maybe".... Pin-it will find it! He's the MAN!!

Not sure on the lights. I am away from access to the schematic. I would check the jones plugs in the backbox and also in the cabinet. Just a wiggle might be all you need. The controlled lights may be on a fused circuit. Check your fuses too. Sometimes in Bally games, the fuse holders crap out. This could be part of the problem too.
