Re: Alternator install help
The wire you speak of, is it the negative battery cable?

Re: Alternator install help
What do you mean by extra? Do you already have the one power hooked to the starter and the one to the back of the alternator?

Re: Alternator install help
So thats the wire that goes to the positive battery post? Is it built into the positive battery cable? Got a pic of the other end of that wire?

Re: Alternator install help
Isn't that your charging wire? If it is, it goes on the little stud with a nut on the back of your alternator.

Re: Alternator install help
If your alternate is working and charging your battery with no issues, tape it off and zip tie it secure and you should be fine. My bat cables don't even have that wire.

Re: Alternator install help
That is the charge wire for the back of the Altenator. It is a must! I would hook it up and find out where the other wire leads off to. Might be a Previous owner hook up for something else.

Re: Alternator install help
Where does the wire that you already hooked up go to? I'm guessing either to the starter or to the fuse block. Either way, you should just hook up both wires under the stud/nut on the alternator.
