After moving the game and cleaning contacts, a game starts (game over light goes out, ball 1 shows) but the flippers do nothing and no switches score. Fuses test good.
Game starts but flippers are dead and nothing scores: dirty relay switches
Cause: Power to the playfield features passes through switch stacks on the tilt, reset, lock and game over relays; a dirty or misadjusted stack there leaves the flippers and scoring dead.
Checks
- Use the schematic to trace the feed for the flippers and scoring back through the relay switch stacks.
- With a game started on ball 1, check that the tilt, reset and game over relay switches in that path are closed.
Fix
- Clean and adjust the tilt, reset, lock and game over relay switches in the feed path, and clean the playfield plug contacts.
