Quoted from spinal:If the fish paper wears or breaks, the player can get a shock from the flipper buttons. Replace the fish paper (or use electrical tape)
Additionally, you can slip a small piece of shrink tubing on the leg of the flipper activation link (older games only) where it comes in contact with the switch blades to further insulate the flipper buttons.
Quoted from schudel5:Didn't Canada require a 120V to 120V isolation transformer as well in their games?
I've seen isolation transformers inside of some woodrails. They were likely from Canada, eh?
Quoted from cottonm4:My pins are grounded but my house is not.
My house was built in 1957 and two-wire romex is all that is in my walls. I used to have a drawer full of those little gray adapters that that let you plug a 3-prong tool to a 2-prong outlet. That got tiresome, so one day I replaced all of my 2-prong outlets with 3-prong outlets.
Rewiring the house with grounded Romex costs too much but I'll probably have to reinstall the 2-prong outlets when I go to sell.
If your house wiring isn't grounded your pins can't be grounded either (unless they're not in your house).
Quoted from Darcy:So I should question my self when I want to use this 1915 Universal Toaster, with a 2 prong cloth cord?
Wow, that's cool! What's the worst that can happen; you electrocute your toast?
Quoted from radium:Gottlieb Aloha and Flash Gordon, why?
Because the "Flash Gordon" was probably grounded, and the "Aloha" (likely had the voltage leak) was not. Same thing happened to me when touching an EM game next to a SS game. The whole reason you get zapped is when you become the path to ground.
Quoted from KenLayton:In my opinion, if the machine originally had a 2 wire power cord, it stays with a 2 wire power cord. Naturally if the original 2 wire cord is frayed, cracked, hardened, or otherwise in a condition needing replacement, it will get a brand new 2 wire cord.
Why downvote the guy? He's only saying what the first option of the poll asks.
Quoted from cottonm4:That toaster reminds me of the hot dog cookers we used to make in 8th grade basic electricity class: Make and install two brass prongs to a piece of plexiglass, attach a power cord to the prongs, skewer the dog onto the prongs and plug in. Sizzle sizzle.
This pic a commercial version. It at least has a safety cover. We flew without a net. The ones we made were of the suicide type. Skewer, plug in, and hopefully unplug before you go to pull the hot dog off of the stakes.Good lord, can you imagine the liability for the school system if something like this was made by Johnny today?
Those look like hunks of kielbasa.
Quoted from o-din:There are always purists that when they rewire their house, they choose to go with factory correct aluminum.
Aluminum romex. Every fireman's dream!
Quoted from KenLayton:Because the Flash Gordon probably had the ground prong chopped off the power cord, or the "grounded" wall outlet had a fault, or the games were plugged into an outlet strip which has a fault.
No. The reason you get blasted is when you become part of the circuit. That is, when one part of you touches something that is electrically hot, and another part of you touches something that is grounded. You can touch or even grab a hot wire as long as your not touching anything else that has a lower potential; that is, ground. This is exactly why a squirrel can run along a power line, or birds can perch on one without any ill effects.
I was at a friend's house once, and touched his Williams "Top Hand" and "Back to the Future" at the same time. Apparently, the "Top Hand" had a voltage leak to the coin door, and the "BTTF" having a three prong plug, was grounded. I got a pretty nasty jolt. Now, if I was only touching the "Top Hand", I would not have gotten shocked. Not that there wasn't a serious issue with that game, but if I hadn't grounded myself by touching the other game, I wouldn't have gotten shocked.
Quoted from pinhead52:The white return of any circuit is tied to earth ground in the panel...
That's true in many cases, but it does not automatically ground your two prong plug games. They're not grounded, period. Whether one sees this as being necessarily hazardous or not is what this discussion really centers on.
Quoted from o-din:Ooo, you got the full 110v on that one, didn't ya!
Oh, man. It really smarted!
Quoted from pinhead52:Of course, you certainly would not tie the white to any metal in a game, this creates nasty ground loops
Yeah, and if you reversed the line cord plug.....
