One or more flash lamps do not work on a game before Big Guns.

Flashers dead on early games: resistors broken on under-playfield flasher boards

Cause: The flash lamp resistors sit on small boards under the playfield, where vibration and heat crack them or shake them off. Both the 330 ohm 7 W R1 and the 5 ohm 10 W R2 fail.

Checks

  • Inspect the single and double flasher boards under the playfield for missing, cracked or desoldered resistors.

Fix

  • Replace R1 (330 ohm 7 W) and R2 (5 ohm 10 W) as needed and resolder the board.
