The purpose of this blog is to chronicle the restoration of my 1934 Bally Signal pinball machine. At the start of my restoration project I began sending updates to my family. My sister suggested I blog it instead so that anybody who may be interested in a restoration project like this would have access. This is my first pinball restoration, so expect some mistakes.

Electrical switches under the shutter
Under the shutter is a board where the electrical switches and bell are. When the balls drop either through the Signal hole or when the shutter is pushed forward at the start of a new game, they roll down this board to the ball collection area. When the balls roll over the leaf switches, they close and touch the contact on the top half of the switch to the bottom half which lies under the table which close the electrical connection which activates the solenoid which pushes the armature inside the coil upwards which in turn opens the gates on the playing field. All of this is run by a 6 volt battery.
