There is a metal lanyard that is used for support when you fold down the translite. When the translite is in the upright position, the lanyard has a lot of slack and can move around inside the backbox. If it happens to come in contact with the wrong thing ... POOF, you just fried your game. I used some heat shrink tubing to insulate the entire length of the lanyard. In my opinion, everyone who owns a Safe Cracker should perform this mod.
