In Reply to: Grounding a metal cabinet posted by JoelS on 11, 2001 at 12:20 PM:
When I got my cab I got zapped every now and then from the metal parts, I was using an adapter to use it in a two-prong outlet. When I replaced the outlet with a newer three prong, I found out that it was wired backwards! So, definately check the outlet(thin side should be hot, large side neutral). Hasn't shocked me since.
The orginal ground was probably routed to the Power Supply as someone else has said.
: 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?
