Battery cables -where does the negative go?

It may be original, but someone has had that cable off at one point. The factory would not have placed that cable under the throttle spring bracket, because it could possibly work loose. That's just way incorrect. The factory did some stupid stuff, but not that stupid.


Yes- after 50+ years. Things like oil filters, battery cables etc are changed. But most people are not going to remove one bolt just to move it else where. But I agree- that’s not the spot. My concern is the factory head was not drilled- so now what?
Thanks for your help.
