That lower harness won't get you what you need. It connects the coin door, tilt panel, flipper buttons, power in and service outlet, speaker and knocker to the power rectifier board. Also, the Bally power supply was in the head, yours is in the lower cab. Do you have enough wire to make it to the boards if you got the plugs on the end? Because looking at your picture I am pretty certain it was cut a ways back from the plugs. And there should be two sets. One that went from the play field almost straight down to the power board with around 6 wires and one that runs up to the head with 50-60 wires.

Not fun, but not impossible either. I can walk you through most of it. It would not be hard to write out a key to convert the different wires from one game to another. Several people on here have run a game with a non matching harness. The trick is knowing what you are getting was also not cut short. I could make you up a set of plugs with say 3' of wire in the right colors that you could then join to the existing wires. (Preferably soldered wire to wire and then covered with shrink wrap.) It would be less work than replacing the whole deal but might cost more than a used harness and there is the possibility of future problems with that many connections. One of my first machines was a "Duotron" with all of the wires cut at the head. The plugs and tails were still there, though and I was able to join them all back together. A PIA for sure, but I got it up and running.

Or, find someone who can make you a custom set of pigtails in the proper color combos.

You found him.

I could. Planning on doing Star Gazer and EBD play field harnesses anyways. Have to do a little more studying. Stern's early schematics really suck!

Shawn

Thanks! And agreed. I think I have ten 28 pin connectors left from a bag I bought from you several years ago. Meanwhile, a 25 plus a 3 plus two drops of super glue will have to do.

Just a cursory glance but it appears the coil in pic 1 has been worked on. The soldering job isn't as neat and the diode is different. The bottom picture looks factory. And a continuity check would show them all connected - by the daisy-chained yellow wire. If you disconnect it in the bottom pictured coil it shouldn't happen again. Taking some stabs here. Anyone else?

Shawn

"Interestingly." Yeah, that's one way to put it! I've seen a couple of discrepancies here and there but that one is pretty bad. Thanks for the input.

If you disconnect the single yellow you can check continuity again to know which black/orange wire is which and then attach them to the appropriate wire on the pigtails. No need to run new wire. And then reattach the yellow and it should all be good.

It was probably that day the black/blue reel on the line ran out and someone was too lazy to go get a fresh reel.
