Mr. Pinball Tip:

The main problem with Gottlieb System 1 games is that the grounds are not solid. All the grounds in the machine are attached to a grounding strip on the bottom of the main cabinet. The problem with this strip is that the terminals were just pressed on. Solder all the grounds solidly to the strip so prevent the floating ground problem. This will prevent all sorts of wacky behavior in your Gottlieb System 1 games.
