Sounds like the trouble is that you have to many wires connected to the case already.
Yes, you can ground it, but you should probably find out what the trouble is since it seems like you have a short to the case... and grounding it will only make it worse.
Whats the setup in the cabinet? computer in a self contained case? powersupply laying around? How about encoders? Are they touching metal?
You might want to get everything working with all your equipment outside the cabinet and find the trouble. I would be worried that it my fry something else.
: I have a metal cabinet (Taito Egret 29") that is connected to power using a 3 wire cable with the ground pin (and wire) removed. When I turn the cabinet on and plug the video cable into the computer I see a rather large spark. After that I seem to be able to unconnect and reconnect the video without seeing the spark. I wasn't too concerned until last night when I had one hand on the computer case and touched the arcade before connecting the video cable. Woah.
: Is it safe to change the power cord to a heavy duty 3 wire cable and attach the ground wire directly to the metal case?
