Fusing the special coils on Laser War to Playboy

Steps

• Data East service bulletin 20 calls for a separate fuse on each special coil; these games left the factory without them (fuses were built in from Monday Night Football).
• Under the playfield, find the blue wire to each pop bumper, slingshot and kickback coil.
• Splice an inline fuse holder into each blue wire and fit a 2.5 A slow-blow fuse.
• While there, adjust the pop bumper spoon switches and check the coil mounting and yokes.
