Maybe we should start an "Idiot" thread. A couple weeks ago, I stole a fuse from my SuperSonic machine for another machine I was working on because I had no 3/4 Amp fuses. When I got some more, I replaced it, then found out none of my controlled lighting was working. Looked inside, saw that I had snapped the fuse in between fuseholders instead of into the right one, DOH. Applied the high voltage DC (200V +) to the 5V lighting buss. Replaced all circuit boards and power supply one by one with another Bally machine to troubleshoot, nothing changed, wtf? Ended up that I fried every controlled light bulb in probably a nanosecond when I hit them with the high voltage, quantity of 74. Got away cheap, still feeling pretty stupid.........
