The game starts but never counts bonus or moves to the next ball. The outhole coil fires in test, but switch test never sees the outhole switch.

Game never reaches ball 2: outhole switch shorted by its stiffener

Cause: The stiffener on the ground side of the outhole switch was touching the switch blade, holding the input low.

Checks

• With a logic probe, check whether the outhole input on the CPU board is stuck low.
• Inspect the outhole switch blades and stiffeners for anything touching.

Fix

• Bend or reposition the stiffener so it clears the switch blade, then re-gap the switch.

Systems

• Gottlieb System 1
