on my 71 chevelle 454, i was getting no response from turning the key on occasion. imy battery is in the trunk. i followed my battery cables all the way to the block. they are fine. but the wires from the starter to the alternator are corroted. it has a green tint on the wire. is ther a ground out somewhere? whats going on?? any possible suggestions? i did replace the battery terminal connectors and it starts now, but that cant be the reason.
