This is a short series of videos on fixing a Gottlieb Card Whiz (two player version of Royal Flush) EM pinball machine that was having problems advancing the next player/ball. Upon investigation I discovered a coil that was burned and fell apart when I pulled it out of the assembly. I’ll go over replacing the coil.
One of the first things you have to do when you get an original Gottlieb System 80 game is deal with their on-board NiCad battery pack, if it has not already been addressed. Gottlieb installed these batteries on the actual MPU board itself and like on other games, it’s a common cause of serious problems with the game. The batteries begin to leak after awhile, releasing electrolytes that corrode the MPU board and the components on it. This can happen even if you don’t see any obvious leaks. The batteries need to be replaced. There are a few options you have to do this: a remote battery pack (3 AA batteries along with a blocking diode to keep them from being charged if they’re not rechargeable batteries), a 2032 lithium coin cell, or my favorite, a 5.5v 1.5F memory capacitor. The memory cap will last the longest and will not destroy any components on the board. It will keep a charge for at least a month or more without power. Here’s a video of me adding this fix to a Gottlieb System 80B MPU
I got a new pinball machine in the other day and one of the flippers was sticking up. In this video series I go over examining what was wrong and how to address it. There are a number of causes for stuck flippers. The most common cause is a dirty or worn coil sleeve. Also sometimes there can be a hang up with the EOS (end of stroke) switch (more common on Bally/WMS than older Bally or Gottlieb games).
People were complaining that one of the flippers in our Gottlieb “Slick Chick” was not working properly. The metal was fatigued on the assembly and the switch contacts were well worn, so I’ve ordered new switches and am showing how to remove and replace the flipper switches and make your flippers perform much better.
Here’s an update on the status of the restoration of a 1987 Bally “Escape from the Lost World” pinball machine. When I got this machine it was in pieces and very dirty. Come see how far it’s progressed!
