After a credit the game starts its reset, but the hold relay will not stay in and the game never starts; switches and coils stay dead.

Game resets but will not start: adjust hold relay and reset-completed relay latch

Cause: Relay adjustment. The hold and hold/tilt relay coils had been bad and were replaced; after that the hold relay would not stay in and the reset-completed relay latch did not move far enough to lock.

Checks

• Find the hold relay's self-holding contact on the schematic and clean and gap it.
• Check the relay coil mounting; a loose or misplaced coil hold-down screw can stop the armature pulling in fully.
• Watch the reset-completed relay during reset and see whether its latch fully engages.

Fix

• Adjust the hold relay coil hold-down so the relay pulls in and holds.
• Adjust the reset-completed relay latch so it travels far enough to latch.

EM games carry line voltage and 120 V circuits in the cabinet and backbox; unplug the game before adjusting relays.
