TL;DR

Spooky Pinball servo replacement and tuning tutorial for all machine servos.

Summary

Charlie from Spooky Pinball demonstrates how to replace and troubleshoot servo motors in Spooky and AMH pinball machines. The video covers servo replacement, menu navigation, positioning adjustment, and fine-tuning using the Servo Default function to prevent mechanical binding and vibration.

Key Claims

  • Servos in Spooky/AMH games are controlled by CPU and do not require limit switches at beginning or end positions

    high confidence · Charlie, Spooky Pinball, opening explanation of servo technology

  • All servos in Spooky/AMH games operate on the same principle and can be accessed and adjusted through the same menu system

    high confidence · Charlie, Spooky Pinball, throughout video

  • Servo binding/pushing against mechanical stops causes vibration that will damage the servo if not corrected

    high confidence · Charlie, Spooky Pinball, servo adjustment section

  • Servo Default function allows fine-tuning of servo position limits to prevent binding, accessible through the machine menu

    high confidence · Charlie, Spooky Pinball, during Servo Default adjustment demonstration

Notable Quotes

  • “Servos are different from a DC motor in a traditional pinball machine as in the computer or the CPU unit tells this thing where to go and it doesn't necessarily need a switch at the beginning or the end to tell you where to stop.”

  • “If this is pushing against that plastic, it's going to shake like this, and you'll feel it...This thing will shake and it will vibrate. And that will murder your new servo.”

    [name withheld pending review]@ 3:26 — Practical warning about servo binding and failure modes

  • “All this information is available on our website. This is in the AMH switch matrix at the bottom of the chart. It'll tell you which servo controls which feature or toy, ghost, door, elevator, etc.”

Hello, this is Charlie from Spooky Pinball and right now I'm shooting a video explaining how to change a door servo. This will work for basically all the servos in the game, they're all the same principle. Servos are different from a DC motor in a traditional pinball machine as in the computer or the CPU unit tells this thing where to go and it doesn't necessarily need a switch at the beginning or the end to tell you where to stop. Inside the coin door, there's your servo right there. We're going to back out. Inside the coin door, there are two buttons, green and red. Green means go. Green means go into the menu. Red means stop, back out of the menu. So what we're going to do is go into the menu, and we're going to go to servo. Hit the green button again, and you will see door open. Now I use the flippers to toggle through all these different little settings here. This is for all the servos in the game.
1:06
And we're going to go to door close. That's using the flippers left and right, back and forth. Hit the green button and boom you can really see it but it just sent that little servo to the closed position Now showing you underneath Say your servo died, it's got that funny smokey smell. This is your auxiliary board. This is the servo that is in the game right now. Plugs into position 2 for the door. Servos are laid at 0 through 3. Technically it's 4, 0, 1, 2, 3. All this information is available on our website. This is in the AMH switch matrix at the bottom of the chart. It'll tell you which servo controls which feature or toy, ghost, door, elevator, etc. So anyway, it's four screws. You take this servo out. It's actually positioned this way in the game. Take this servo out, plug it into the auxiliary board. This is located underneath the play field, and that gets you basically to what you see on camera right now.
2:11
We just sent that puppy to closed. Here is your door, here is your screwdriver. It is a single screw. So we are going to put the door on, sorry for blocking this with my hand, I'll get it out of the way as soon as humanly possible in the closed position it down until she good and snug Don over strip it It good and tight It not dragging on the play field Now we're going to go back out to the menu here. You see it says door closed. I'm going to use the flippers to cycle over to door open.
3:06
Before I press the green button again, we'll go back, hit the green button, boom, door is open. Now what you want to check with any servo is that it's not pushing to get somewhere. If this is pushing against that plastic, it's going to shake like this, and you'll feel it. You put your finger on top of it, you will feel it.
3:26
Same here, if we send it to close, if it's pushing against the metal, like right in the corner there, You will feel it. This thing will shake and it will vibrate. And that will murder your new servo. So you don't want to do that. This one is pretty good. But, say it's not very good.
3:41
Let's back out. We're going to hit the red button to exit. We're going to go to something called Servo Default. Hit the green button to go in.
3:53
Door open. Six We go to door close just so I can show you how to adjust this Using the flipper again we hit the green button Go back to the door Zoom in on the door And here what happens See how I moving the flippers and it moving just a tiny bit? See it's pushing up against that steel there? You can just go back, back, back. Good. Hit the green button. Hit the red button. Saves it to the EEPROM. So you can fine tune adjust that servo with that. That also works on basically every servo in the game. The elevator, the target bank up and down, any of those. If they're shaking, you want to get it to stop shaking, just use your servo defaults. You go in, you change it, and it's good to go. And that is it. That is all you need to know. You might want to go into your menu, check it one more time. Servo. We'll go door open, bing. Double check it again, change your defaults there, you can push it forward a little bit if you need to. Good to go. Door closed. Not shaking, put your finger on it, good to go. Boom, you're done. That's it. Hope that helps. If you have any questions, my email is charlie at spookypinball.com.
