This dang pachislo machine only has a two prong plug, and I only really noticed it when I kept getting a mild shock/buzz from the cabinet. The inside metal pieces are attached with ground wires, but I don't see how it's supposed to be grounded (through the neutral??).
Any ideas on how to ground? I am thinking of just sticking a spare isolating transformer on it, but maybe I should rig a ground to the cabinet ground? You electrical fellers might be able to lead me in the right direction here...
Oh, and the cab looks to have been factory built to have that non grounded plug.
