I’m a firm believer of being patient in the pinball hunt. I’ve always wanted a Bally Wizard EM. It’s such a great game and has such beautiful artwork. They made a bunch of them so why has it taken so long? Because they’re an A-list game and often command A-list prices and I wanted a good deal. I waited and got more than what I wanted…
Here’s a video I made awhile back that I don’t see linked on my main site so I thought i’d include it. It’s a short video on how to diagnose problems with score reel switches when you turn the game on and the score reels just seem to spin forever and not reset/start the game.
As I work on restoring another game (Bally EM “Air Aces”), I demo my approach towards making the game more reliable and stable by replacing many of the old bulbs with newer LEDs. I also show the difference between the warm and cool white LEDs and how they work.
I was having an issue with a Bally “Supersonic” pinball machine randomly resetting/rebooting. The problem was traced to irregular power coming off the driver board. In this video series I go over a necessary process to bring these old boards back “up to spec” as well as a few improvements that make the game overall more reliable.
In taking an initial look at the latest game I picked up, this Bally “Mystic”, as always my main concern is checking to make sure there’s no significant battery damage on the game. What’s interesting is when I looked at the game, there was no battery on the MPU board. The owners insisted the game saved the high scores, but I didn’t see how? Was there a battery on the underside of the board? I had to pull the MPU out to see.
What I saw was a board that someone had repaired, that had leaking batteries on it. They simply pulled the board and replaced a few damaged components and did not put a battery back in. But they created another issue by not fully-cleaning the board, and as a result, the damage from the leaking battery, even though it was long gone, continued…
Lately, I’ve been developing a big appreciation for the 80s-era Bally games. As a kid I remember them kicking my ass and having unique and interesting rulesets that set them far apart from the Gottliebs and Sterns of the day, so when the chance to pick up a “Mystic” came up, I jumped at it, and drove about three hours to get this game.
Little did I know how special the game would end up being…
As many of you know, one of the biggest problems with pinball machines and repairing them is dealing with leaky batteries on solid state machines, that cause corrosion and all sorts of damage. I’m going to go over how you can completely eliminate this from happening by replacing old-style rechargeable batteries with a high-tech “memory capacitor” that will last longer and not have the same problems that batteries do.
Now lets test the new memory capacitor in the game:
