Black wire with white trace on driver alt?

[shotty]

I have a loosey-goosey wiring dangling right around where the driver side alternator was that I can't locate on the wiring diagram. It's a small wire with a small ring terminal on it, black with white stripe. It's not the tach sense wire, too small to be the ground wire, not part of the two wire plug for the exciter... Not sure what it could be or where it used to go.

It gets hooked to the ground stud. It is not the ground but that is where it goes. M6 hole in the center of the eyelet.

That's where I figured it came from but why isn't it on the wiring diagram and where does it go

I never looked at a wiring diagram. I just learned by taking them apart and putting them back together for 35 years. I do lie. I looked at wiring diagrams but was never able to read them well enough to help me so I just dove in and checked things out. Trial and error with extra caution. Good Luck.
