Quoted from Bublehead:My biggest advise to newly infected pinball zombies from space... now there's a title for ya, is to learn to do your own board repair, basic soldering, replacing transistors, resistors, diodes, IC’s and capacitors, learn how to use a meter to check for shorts and grounds and diodes, how to use heat shrink the right way (put it on BEFORE you solder...), how to troubleshoot a simple electronic circuit using half splitting and simple continuity checks, how to read a schematic, how to manufacture simple brackets and mounts, how to re-rubber , relamp, and wax a playfield, how to rebuild flipper mechs, how to read resistor markings, how to troubleshoot lamp and switch matrices. How to sand, buff, polish, flame polish, chem polish, sand blast, wire wheel, grind, hammer, screw, unscrew, bend, twist, cuss, and spit. That and how to tear a machine down, move it, and set it up again, level it and make sure it is working, use the service menu, make adjustments to game parameters, clear audits, factory reset, change the custom message, set it on free play, how and when to change batteries, how to open the lock bar, how to turn a machine on and off (Gottlieb tap anyone?), how to raise the playfield (please pull the shooter back), how to remove the backglass (where the fuck are the backbox keys? Bueller?), how to clean and clear coin mechs, what that handy tray full of dead rubber, burnt out lamps, and fried coils really is (the coin box you dolt!), how to remove a top hat insert, re-level it, and redecal it, how to remove mylar glue quickly and safely, how to touch up your fuckups from slipped screwdrivers and dropped tools on the playfield. Did I miss any? Edit- yes I forgot applying decals to cabinets/backbox and sourcing replacement parts, and how to adjust all switches- EOS, jets, slings, flippers, rollovers, drop targets, standups, limit, and spinners.
