It looks to me like according to the classic Bally games, my older Stern is wired incorrectly? Is this a correct assumption? It looks to resemble more the wiring from the Williams games.
In this pic, the ribbed plug side is soldered to the right lug, the ground to the center and the smooth plug side soldered to the left tab.
The wires leaving leaving the transformer:brown wire is wired to two white wires, while the blue wire is connected to two black wires.
Should I follow how this wiring is currently? Or change the wiring? I know the game powered on when it was sold to me, but I have not powered it on since.
Thanks for any help, this is one of the last steps I need to do (replace the 3 prong cord) because the ground is snapped off of the one on there now.
