There is a metal piece of wire that comes out of my ground that I think, from reading the forums, is a bond wire. On my old motor it was rusted to the top of it - I'm not sure if there was a screw there holding it or what, because it all just pretty much broken into bits of rust as soon as I tried to remove it. I now have what looks like the two ends of this metal inside a small little metalish "home". On the new motor, there's just a screw that comes up. How am I supposed to connect this and what are the repercussions of not doing it right? Do I just put the cable around the screw and screw it down?
