It is a very mild shock, at first I thought my Carpal Tullen Syndrome was acting up. But then I put my finger right on the bolt and could fell the shock. I checked the ground on the control panel, and I get continuity from the panel to the ground pin on the wall plug. I did recently plug it into an APC brand surge supressor. Any ideas what would be causing this shock?
 
is the game on a concrete floor were you wearing shoes

lol
i have found on my games (games are all in storage room with concrete floor)
that even when setup proper with correct grounds if i take off my shoes and touch bolts or other metal parts i get a little zap guess im a better coundetor than the 20 year old ground wires in the cabs lol
if im wearing shoes i dont get a zap


other than that make shure your apc is a grounded one and checkto be shure the cab has all the ground strap/wires hooked up to one another at some point
 
Try plugging it directly into a wall socket. The APC might have a faulty ground.

Also, just because you get continuity between the ground and a control panel doesn't mean that there is sufficient loading capability for it to ground adequately. Check the connections for corrosion and make sure there is a solid gound on the CP.

Good point I am on concrete floor. I found that on closer inspection my coin door gound wire was broken. I repaired it and the shock went away. Weird since the shock was coming from the control panel.

I also think that the lug was not fully plugged into the APC. I found when I went to plug it back in it only went in half way easily, and I really had to push to get it in all the way. So not sure what the problem is, but it is gone now! Thanks eveyone!
