Found some good info here on Pimside about the sensor but I'd like to clarify something which might help me setting up my new sensor on WOZ. Does the sensor, sense the magnet on the flying monkey when it comes down to capture the ball or does it sense the big magnet on the playfield? Trying to understand exactly what it's doing so I might have a better chance of dialing it in correctly. Appreciate any info you might have. Thanks

Good info here. So I'm guessing the sensor, senses a magnetic field thru the ball while it's captured on the playfield magnet, yes? No issues picking up the ball as I made the same adjustment kahanaohanaso did when I first received the machine. It did the same thing, monkey didn't go quite far enough down the worm gear.

Perfect. Thank you. I can now install the new sensor with a bit of an education. Much appreciation to all who responded.

Absolutely will. Should have my monitor driver board delivered the beginning of this week and I'll be more than happy to update with some photos.

Thanks for the info MK6PIN, Do you have the chip on the sensor board facing the backboard or facing away? Would you happen to have a photo of your installation of the sensor? Thanks.

Can't thank you all enough. Nice to get this info so quickly and easily. Should have joined Pinside a long time ago. When dirt was made, and me.

With everyone's help I was able to place the sensor in the perfect place for my pin. Works perfectly now. The monkey mechanism clears the little sensor with no issue. It's directly behind the playfield magnet but high up on the board. Now it only senses the magnetized ball. Pics are hard to get in there so these were the best I can do. Hope it helps.

Second screw in. Just making sure it was working during game play. Working perfectly from both right and left orbit now. And very true, it's a very slight adjustment either way to get it just right. Worth the effort for sure.
