A ball in the pit is never kicked back out. The pit switch works in switch test, but the coil doesn't fire in coil test.

Ball sits in the pit and nothing kicks it out: broken coil wire

Cause: One of the wires had broken off the kicker coil's lug.

Checks

• Test the coil in solenoid test, then look at the coil lugs for a wire that has snapped off.

Fix

• Resolder the wire to the coil lug.

Systems

• Williams System 11C
