I have 71 chevelle with a 350 out of 72 truck or something like that. My alternator went out on me 2 days ago. I went to O'reilly's to get another one. I put it on and everything. I pull off the battery cable and it dies. I posted a forum on a different website and he tells me that I have to have a wire running from the internal regulator of the alternator(male connector F) to the back of the alternator where the battery hooks up. So I do that, pull the battery cable off it works so I do it again with my headlights on. It blows the headlights out. I really have no clue as to why it did that, but I when I pull th cable off the dome light inside, when its on, gets super bright like its gettin too much juice, that would explain the headlights. Its supose to be a 61amp alternator designed for my car. Oem I guess. Can someone point me in the right direction??
