In the middle of a game it stopped responding. Now it won't start a game or reset the score reels; the start relay moves the score motor a little and then everything stops.

Won't start a game or reset the score reels: burnt game-over relay coil

Cause: The game-over relay coil had burnt out.

Checks

• Check the fuses and fuse holders at the transformer and on the motor board.
• Follow the start-up sequence in the manual step by step to see where it stops.
• Inspect the relay coils involved in start-up for burnt or open windings.

Fix

• Replace the game-over relay coil, and find out why it overheated (for example a switch that kept it energized).

Systems
