A common problem in many games that use stand-up targets is after awhile the targets lean backwards and will throw the ball up into the air, causing it to fly all over the place, get stuck or break other areas of the playfield. Here’s a quick little trick to reduce this from happening.
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:
Here’s source info on the caps:
1.5f 5.5f “super capacitors” at Mouser Electronics.
Specific item I used:
You can also get these from Great Plains:
Product ID: CER-1.5F-5V
Capacitor, Radial Electroltyic, 1.5F, 5V
Capacitor, 1.5F, 5V, 85C, Radial Electrolytic
Manufacturer Part Number: EECF5R5U155
Diameter: 21.5mm, Height: 8mm, Lead Spacing: 5
One of the biggest problems with vintage solid-state pinball games is damage to the circuit boards from leaking batteries. Here I show you how to install a remote battery pack so the batteries are away from the sensitive circuit boards, eliminating the possibility of them leaking electrolyte and causing corrosion and other damage to the pinball machine’s electronics.
This type of remote battery pack will work with almost all major pinball systems. The main thing to note is some games by default used rechargeable batteries (many Gottlieb and Bally systems) while others used non-rechargeables (WPC). If you use a remote battery pack on games that by default used rechargeable batteries, install a blocking diode in the path of the battery pack to keep the batteries from having power supplied back to them. Doing this with non-rechargeable batteries can result in bad things like batteries exploding.
