In Destroy the Ring the first ring shot counts, but the second never does, and the mode times out. The ring works for other modes and its switches pass switch test.

Destroy the Ring stalls on the second shot: spinner switch misses one direction

Cause: The second Destroy the Ring shot needs the switches in the order spinner, ring, trough. The spinner switch only registered when the spinner turned one way, not the way a ball going up the ring ramp turns it.

Checks

• In switch test, flick the spinner in each direction and watch for hits both ways.
• Check the ring switches and the exit switch behind the ring with a ball moving at speed, and check the balls are not magnetised.

Fix

• Bend the spinner switch wire so the spinner closes it in both directions, then test the mode again.

Systems

• Sega/Stern Whitestar
