After kicking the ball to the shooter lane, the outhole coil often fires a second time. Switch gaps, the wireform and the coil diode all check out.

Outhole kicker sometimes fires twice after ejecting: replace the trough switch

Cause: The original trough leaf switch was giving a false closure as it aged.

Checks

• Watch the trough switch in switch test while the kicker fires.

Fix

• Replace the trough switch; a microswitch was used here.

Systems

• Williams System 6 / 6A

Games

• Gorgar

Related tips

• Ball rolls back to the outhole instead of reaching the shooter lane
• Ball in the trough not registering: switch wire actuator dangling or bent
• New coil's diode faces the other way: keep each wire on the same diode end
