If a ball gets hit into the lost mines scoop it will sometimes not be detected. I think I figured out that it is going up the tunnel just a little bit and getting hung up on the kicker. The ball search will eventually fire the coil, and the ball will fall into the correct spot.

Have you guys run into this before? Any ideas on how to prevent this?

The adjustment screws were not enough. But bending the bracket did the trick. Thanks!

My left flipper button is much softer than my right one. Looking at them, it looks like the interrupter on the left is missing the second brass blade. Specifically, the right one looks to have 2 blades, and the left one has 1. Is this something that can be ordered? All I see are entire replacements for the board.

Attached are pic, I was too lazy to take the glass of this morning when I took pics, ha. I hope you get the idea though.

Thanks!

I installed the GI and LED OCD boards on my White Water. the GI OCD made a huge difference. Before, anytime the game faded the GI, they would just strobe. The effect the LED OCD board has is much more subtle.

I made a before and after video of the fading effects in the test menu. I wish I would have taken a before video of the ball lock, that is where you can clearly tell the difference. Before it would just strobe, now it fades the GI out smoothly to nothing as you go into the "cave".

The popper on the ball lock is often unsuccessful in getting it over the "hump". It is worse when there are already 1 or two balls locked. This eventually cases the game to go into a ball search, and then you loose all your locks.

It does seem to happen almost right away when you first turn the game on, so I don't think it has anything to do with the coil getting hot or weak.

Any ideas?

Thanks!

Just a follow up on this. the ball cup looked good, I replaced the sleeve. Still had the issue. So, I swapped the coil with the knocker coil (both AE-23-800). So far so good, It seems to be working correctly now. So, either swapping the coil, or the fresh solder on the wires helped.
