Alternator install help
 
The water pump is in thank you very much! The alternator was bad so I have a new one I put in however....as it is my first time installing one I have an extra hot wire coming directly from battery that I did not re install( stupid newbie mistake) and cannot figure out where it bolts on. Help?

The wire you speak of, is it the negative battery cable?

Nope looks like it is coming from positive side

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?

Here is the picture of what I have left. I have the 2 prongs plugged in and the wire under the nut. This is what is left...I am a newbie at this but I do not remember undoing this wire...but I must have...

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?

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

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.

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.

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.

Yes. I guessin someone ran another wire to the stud for a power sorce for something? Disconnect it and see what doesnt work?
