I recently purchased a Surf Champ (Gottlieb 1976) and when I got it home, I realized the plug was shot. I was going to simply replace the plug, but when I cut the wire, I realized there were just two black-coated wires and a green one in the middle. (See photos)
Both the black wires were smooth - so there was no way to tell which one was "hot" and which on was "neutral." (I supposed the "hot" goes to the copper-colored screw, and the "neutral" to the silver-colored screw, but I'd have to dissect the plug to figure out which wire went to which screw, and even then, I'd have to assume whoever wired this did it properly.)
So I've decided to replace the entire cord. Only problem is, I'm a relative newbie and have never done it. Yes, I've read Vids posts on replacing the plug, line, etc. but want to make sure I am doing this correctly, so I don't kill the game or myself.
(Question: The cord "appears" to be original, as it is part of the wiring harness bundle. Are these the kind of plugs Gottlieb sent out with the game in 1976?)
So I'll purchase a new cord that has black / white / green wiring. Two questions:
1. Can someone confirm that the transformer is currently wired correctly, according to the schematic?
2. If so, then I want to duplicate it with the new cord, correct? So the black wire goes to the fuse (yellow circle); the white wire goes to the "normal" tap bottom (white circle) and the green wire goes to the transformer ground (green circle).
Thanks in advance for your help!
