    The reflex unit is part of the circuits that award increased scores and features. The reflex unit tightens up as the player wins games, and loosens up as the player spends credits or coins. Some operators hacked this unit by re-orienting the wipers on the reflex unit such that the wipers connected to fewer rivets than as was designed by the factory. The result is increased profits for the operator because increased scores and features are awarded less often than they otherwise would be awarded.

    Here is my write-up, with extensive photos, for how to detect if your reflex unit has been hacked, and how to return it to as it was designed.

    Nice work Robert! I'll definitely be checking mine out.

    A couple things that may be worth mentioning. When the screws are being put back into the disc, if it's at all like other bakelite disc units, you may be able to rotate the disc slightly before tightening the screws to precisely align the contacts and rivets. I'm not sure if that holds true on the reflex units, but it might.

    The other thing that can be done, but it isn't related to the topic of your document, is changing the gears on the reflex unit. You can get various numbered gears which change the gear ratio and allow the reflex to tighten or loosen more or less quickly.

    It does hold true here as well. You'd need to loosen the third screw in order to do this.

    Correct.
