WPC-S and WPC-95 games to 120 V

Steps

• Rewire the voltage plug on top of the metal power box inside the coin door to the 120 V pattern; on a European game, add the pink wire and move the black and white ones.
• For "America", set CPU DIP switches 1 and 2 OFF and switches 3 to 8 ON.
• Plug the knocker back into the harness above the CPU board; European games use that circuit for a coin meter.
• Change the main fuse: on WPC-S from 5 A slow-blow to 8 A fast-blow; on WPC-95 from T4.0 A to T5.0 A.
• Fit a 130 V or 150 V MOV.

Line voltage is present in the power box, line cord and transformer wiring; unplug the game before working there.
