I hope you learned something about figuring out the process of how and why things work, but more importantly, how to think through the troubleshooting process. I replaced the diode and the game was back to normal. I’ll go into more detail on that in the same upcoming post.įortunately nothing else was damaged.

Thats because starting with System 11B games, the ones with the auxiliary power board below the power supply, through WPC-95 have the diodes on the driver board. You may have noticed that some games don’t have any diodes on the coils.
In an upcoming post I’ll go into more detail as to why the coils all have diodes on them. The diodes are there to protect the transistor and the rest of the drive circuitry. There’s one for each transistor and D2 was shorted. There’s only a few components on that board so that really leaves only one thing, the diodes. I pulled the board and measured each of the transistors and they all read fine. This isolated the problem to the magnet driver board. Bally Addams Family pinball machine magnet driver board mounted under the fuse playfield. I unplugged the connectors on the magnet driver board under the playfield and the game stopped shutting down. I unplugged each magnet but the game would still shut down on the magnet test. Whenever it was fired it would cause the game to freak out and reset. The Addams Family is a pinball machine from March 1992, manufactured by Bally Manufacturing Co. I was able to track the problem down to one of the playfield magnets. Unfortunately I didn’t save the video so I can’t show it to you here. The problem is I couldn’t see what test it was failing on, so I took my phone out and made a video of the display during the test and played it back to see where the failure point was. That wasn’t the case here so I put the game into coil test and after so many tests in, it would shut down, always at the same spot. William’s WPC diver board power connector J101 detail. Usually the two red wires will overheat causing weak connections which results in reduced current flow. When this happens the first thing to check/replace are the two bridge rectifiers under the heat sink.Īnother place to check is the power input connector J101 on the driver board, pins 1 and 2. Typically, William’s WPC games with random shutdown problems, will shut down when hitting the flippers, usually when hitting both at once. I start a game and after a minute or two the game shuts down.
I get a call from a previous customer who tells me his Bally Addams Family pinball is randomly shutting down. If your game doesn’t already have them, consider investing in them, ASAP Underside of a Bally Addams Family pinball machine playfield showing added on fuse to protect the magnets. To protect the game and playfield, several aftermarket parts suppliers make a simple fuse kit that plugs inline with the magnet connectors. They aren’t designed to stay on for any length of time. They are meant to have a short duty cycle which just means they are intended to only be pulsed in short bursts. Transistor failures when they lock on will cause the magnet to overheat and eventually burn the playfield. One of the common problem areas on Addams Family is the center of the playfield where the three magnets are located.
Unfortunately, with all great games, they are usually heavily played and worn. It had broken all sales records for flipper games up to that point. According to 21,270 units were produced including 1000 Gold Special Editions. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.Arguably, Bally’s Addams Family is one of the greatest titles ever produced. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file.
