I found one wire in my williams ski club that is burned to a crisp. It goes to the first rollover light socket in the sequence. It is in the middle of the under pf wire bundle. I started to open it up to see if I can find the color code but only got in 5" or so ( dont have schematics yet). None of the other wires around it seem affected. As I'm cleaning I also see the rollover advance unit stepper has crispy wires as well which makes sense.

But I didn't find any burnt wires on the bottom panel or jones plugs

So the question is what would cause this, over fused and a short combination in that circuit.

And do I need to run all new wire and tie it to outside of wire bundle and then run new wire around the stepper disk? I assume I shouldnt try to leave it as is

Also this is my first mid 60's williams. Is there a trick to removing the stepper disks? They dont pop off like the 70s models. I thought it was the set screw on back cog but still wont budge.
Thanks

Thanks I already checked alpine on ipdb wire colors are different in a few spots so I don’t think it’s going to help
