Gottlieb System 3: voltage plug A12J5 wire colours

The plug wire colour shows the setting: brown/white 100 V, red/white 110 V, orange/white 120 V, yellow/white 200 V, green/white 220 V, blue/white 240 V. Its pins are not the .062" round Molex type, so a different extractor and pins are needed to rewire it.

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