2 Game-Specific Issues

There is a thin wire running from the 8 driver board (right side of backbox) to the single drop target reset coil on the playfield. Make sure this wire is present and secure, as coils will lock on if not. Replace this wire with a thicker variant to help prevent it breaking from vibration and stress.

You might remove the three wires from the lug ( purple wire/green stripe, the thin one looks more lavender) and solder to a single wire and solder the single wire to the coil lug. that way if it ever breaks off from vibration, the three stay together and don't knock out a transistor on the small driver board and lock on a subway coil.

Missing ball or Extra Multi-Ball

A common problem is broken wires on the trough optical board(s), especially the large 270 ohm resistors. One way to test is to put the machine in switch edge test mode and bang on the playfield just above the flippers to see if any switch edges register. They should not. Replacement boards are available with shock mounts or you can alter your own boards by drilling out the holes and adding grommets. <<LINK TO CONVERSION INSTRUCTIONS NEEDED.>>
