Diagnosing problems with Mist Multiball mechanism on Bram Stoker’s Dracula

Diagnosing problems with the mist multi-ball assembly on a Bally/WMS Bram Stoker’s Dracula pinball machine. In this case, we were not getting power to the motor, which is supplied from the 20vdc circuit on the power driver board (which also powers the flash lamps). In this series of videos I show how to test the mist motor, and where you check for power and back-trace it to the driver board, then identify which components are related to this problem and how to fix it.

Bram Stoker’s “Dracula” – how to disassemble the coffin and service the pop bumper underneath

I recently had a pop bumper bracket on BSD break and I realized this wasn’t an easy fix. To get to the top of the pop bumper you have to almost completely disassemble the coffin assembly, which isn’t obvious. So I made a video on this process. Enjoy!

Below is a time-lapse of the process:

For the third part, here’s a nice video on how to rebuild a pop bumper assembly. There are some tricks to this and many times people put these things together wrong.

Pinball Stories #5 – Theater of Magic – “Pinball Karma is real”

We all have our stories of good deals, as well as the deals that get away. This story is a parable about people doing the right thing and why it’s so important and meaningful. Some people believe, “a deal is not a deal until money changes hands”, and other people believe “your word is your bond.” If you’ve been in the pinball community long enough, you’ve run into both types of sellers and buyers. I am a firm believer in choosing honor over profit, and I believe if you treat people well, it comes back around to you. This is one of those deals that landed in my lap that I like to think is the result of all the times I treated others fairly. And it’s a pretty cool story of a very ethical seller.

Upgrading eddy/proximity sensors on Bally/WMS games (Theater of Magic)

Recently I decided to replace the trunk eddy sensor on Theater of Magic with something more reliable than the original Bally/Williams proximity sensors. They are prone to “drifting” and will need regular adjustment. There’s a company that makes an auto-adjusting board that I wanted to try out, so here is my video showing the installation of that new board. This should make the game a little bit more reliable.

Dignosing and fixing a dead WPC MPU board (with RAM upgrade)

In this video series, I am working on a client’s “Dr. Who” pinball machine that wouldn’t boot up. It was just dead. None of the diagnostic LED blinks would blink on the WPC-89 MPU board, so I go over the process of how to identify and isolate the problem, then I upgrade the board with NVRAM (non-volatile memory) so that it will never need batteries again.

“Hey Professor!” First Look: Gilligan’s Island

Here’s the first of another multi-part series of stories on some recent game pick ups.   Come look with me as I discover new pinball machines in the wild and take them back to the lair to examine and restore! This was from a lot of about five games I picked up from a company that was going out of business. This was the main game I wanted but I had to get the entire package. Boo hoo. 😉

The Great Switch Matrix Wild Goose Chase!

Here are six videos of an 8 part series of clips I shot this past week while working on restoring a Bally Theatre of Magic game.

What’s interesting about this series is you can really follow along with me as I fumble around trying to figure out what’s wrong. This is an all too common path many enthusiasts take which often leads them back to the beginning of the trail and emphasizes a number of common troubleshooting principals.

At this point, I have a working game except for two minor glitches with switches: An opto in the ball trough is not working, and it’s causing the game to kick balls into the shooter lane when powered up, and the EOS switches on the flippers are not being registered by the MPU. The solution to both of these issues was finally found and may or may not be what you expect. Watch the series to find out!
