I'm working on a Gottlieb Gold Strike, and have a wire hanging from the ball count unit.

It was clipped to one of the hitch pin clips that secures the ball count unit, but that didn't look like the correct place for it.

I don't see any wires missing from any of the brass rivets, or any other obvious signs of where it may have come from. Any ideas?

Looks like the tab off of a coil. How far will it reach? For the $17.00 question do you have a schematic? Hopefully someone will chime in with a more correct answer.

All the coil tabs are intact.

Yes, I have a schematic. I'm not sure on the wire colors, though.

It doesn't reach too far--maybe about 4" or so.

I'm no expert, but I am looking at a similar schematic for another Gottlieb that is not a Gold Strike.

Wait till Sunday morning for someone to post a photo.

It doesn't look like anything broke off.

OK in your last photo is that a broken tab on the right side of the inside switch stack? (The nuts then to the left just after the two spacers.)

***As for wire colours they are different from game to game so the Black&Red reference is most likely incorrect.***

I considered that may have been a possibility, but each switch leaf seems to have a tab on it.

I got lucky probing with a multimeter and found that the wire toned out to one of the jones plug pins in the backbox. That in turn toned out to one of the transformer lugs. And that toned out to the right most fuse for the lamp circuit.

So, it seems like the wire is somehow part of the lamp circuit. I checked for any signs of broken tabs on the lamp sockets, but didn't spot any.

The wire tones out to the wire braid for the lamp sockets.

The loose wire gets tied to the stepper frame. The tab broke off from the lower, outer bolt on the solenoid bracket:

You'll probably find the rest of the ring terminal under the bolt head.

On my other single player Gottliebs, that switch stack has a long bakelite spacer that prevents the extreme left contacts from touching the next set of contacts. There are also at least 7 wires connected to Gottliebs I have. Gold Strike is an AAB so that may be different as well.

You will need a photo of that switch stack from another Gold Strike, even El Dorado might be different.
I tried, but not just good enough.

For future reference, if you look closely at the bracket bolts in your photo, the one on the left uses a locking star washer, the other uses what looks like a normal washer.

The normal looking one is likely a ring terminal with teeth inside the ring rather than outside the ring.

Also, it looks like your solenoid bracket has cracked in two...

With that broken off wire attaching to the frame of the Ball Count unit, it must be acting as a ground wire. Please correct me if I'm wrong.

Yep, that was it. Thanks!

I have solder tabs on-hand, so I'll fix that tomorrow.

Yeah, it's on the list for my next parts order.
