Vague Electrical Question on a 64

[Hilandr451]

That black & white wire does go to the ammeter and by the looks of your "wiring diagram" you've got posted the wiring shown will work for stock equipment. The factory wiring landed the other wire to the "batt" terminal at the starter. Your diagram isn't clear where that termination is, but it is correct schematically. What ever you do don't connect that return wire to ground!!

Here's what I had to deal with after the P.O. realised that a 1/4-20 bolt has the same diameter as a fuse.......




I kept the "fused" section of my old harness as a shop souvenir
