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.

and lets test it..
