How to test bridge rectifiers (in pinball machines and elsewhere)

The other day I was working on a game and traced the problem back to a blown bridge rectifier, so I thought it might be nice to produce a short little video on how to test/check bridge rectifiers in pinball machines, as well as a little info on what they do.

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.

Repairing/Building plunger/flipper/slingshot linkages

If you have a broken plunger/linkage, you can repair it and replace the broken part for a lot cheaper. Sometimes you can’t find complete linkages but you can get the individual parts or the linkages. Here’s how you can build them, or repair them. It’s been awhile since I did this so I had to refresh my memory of how I did 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.
