I am starting my first EM repair project and didn’t get far before needing some advice. I picked up a 1966 Williams Pitch and Bat project. When I power it up, the score motor runs continuously. After checking fuses, I did a visual inspection. The first thing I noticed was that there was just a single strand of a wire connected to what looked to be the melted inside of the coin meter. When I pulled the coin meter apart, I saw that the coil is crispy. It’s listed as the Total Play Meter on the schematics and it appears that the coil is a B-63-96, which I can't find any reference to from any pinball parts seller. However, the outside of the coin meter housing lists B-6396 as the part number, which leaves me wondering whether I was wrong in thinking B-63-96 was the number for the coil and instead the schematics listed the part number for the entire coin meter. As you can tell from the photos, any markings on my coil burned off a very long time ago. I'd be grateful for any information on the proper coil for the coin meter and suggestions on where to buy a replacement.

Thank you so much for the information and the welcome, Steve! Since I was diagnosing the score motor issue, I thought I better install it just in case, but sounds like it shouldn't be creating the problem I'm having, so I'll skip it. The mystery of the score motor continues, but at least I can rule this out!

Thanks! Good point not to leave that toasty tab loose in the game. (Couldn't resist a chance to post another picture. I've seen plenty of burnt parts when repairing video games, but I'm still impressed that it completely melted off. It must have stunk when it happened!)

Buffett!! It's great to see a familiar face here! I don't have any successes to report quite yet. I'm taking the above advice to just go without replacing the coil. I desperately need to order the schematics since the ones I've found online don't seem to match my game and it's miserable to try to deal with them on a dinky computer screen. I have discovered that my 120v isn't working properly as neither the light bulbs in the front nor the fluorescent bulb in the backglass are illuminating. They both test at about 33v. It appears that 120v is being delivered to the connector, but there seems to be an issue with the neutral line. I'm not getting continuity from the transformer to the connector, so my next quest is to hunt down the breakdown. Given how filthy all the wiring is so you can't tell the colors, and the many connections that are involved, this will be fun! I'm hoping to get the 120v working before I turn back to the issue of my continuously running score motor. Thanks for checking in on me and the game!
