In a game no switches score and no coils, flippers, pops or slings fire, yet every switch and coil works in test.

Nothing scores or fires in a game though tests pass: ball never fed, outhole fuse blown

Cause: The game hadn't seen the balls move through the trough, so play never really started: the fuse for the outhole kicker had blown. Gottlieb System 80 games don't respond until the ball has been fed properly.

Checks

• Start a game and watch whether the outhole kicker fires.
• Check the outhole kicker's fuse.

Fix

• Replace the blown fuse, then find out why it blew.

Systems

• Gottlieb System 80B

Games

• Diamond Lady
