Down by the bottom of the page...

The pics dont work but you should get the idea im not doing all your searching i imagine you can find it tho JUST LOOK

(For future reference this should go in the tech section..)

Funny thing - This thread is the 3rd result in that list!!!

I looked 1/2 down and didnt see it.. I have 3 wires and everything I have read thus far seems to lead me to believe there are two (one ground and one positive lead for power)...

Sorry to ask again but instead of googling for me point me to the link with a picture please?

Thanks,

Kevin

The small wire is ground, and it goes on the top right and uses a bolt to secure it, and the large wire is battery + and goes on the bottom right stud and uses a nut to secure it. Hope this helps.

Ace - I have 3 wires... two that seem to go to positive and the other ground. Is that right? So frustrated with my alternator right now :-( Just want to ensure the simple things like the wiring isn't jacked up.
3 wires and the clip for the sensor I believe.

I'm replacing mine tomorrow. I'll take pictures.

Thank you much. I would appreciate this.

So I couldn't get any clear pictures since it was too dark in my shop, but there's honestly almost no way you can put it on wrong. There are 2 wires and a connector. The small wire (it comes out of the harness for the connector) goes on the top right, and gets secured by the small bolt. It won't fit on the positive post unless you force it. The larger wire (the one that's pretty well on its own) goes on the post at the bottom of the alternator, and gets secured by a nut. The connector connects next to the small wire. Mount, and finish putting things back together.

That's all the wiring I had back there. If you have something else, I'm not sure what it's going to, but I don't think that sounds right to have two wires going to positive. I even spent like 10 minutes looking for any other wires, and couldn't find anything. I also verified with my roommate's Z. His only has one wire at each location.

Thanks for the info. I kind of noticed that the ground wire wouldn't fit over the + wire on the alternator when I was putting it back together. I will try and get back under there and take a picture of what I see to let you guys check it out. I will probably post it in my thread about the alternator not charging the battery. Still need to grab an OEM alternator belt.

Out of curiosity did you just change the alternator because it was due, or you were having charging issues? What did you go with - OEM Reman or an AZ type Alternator.

Thanks!

I wasn't having charging issues...... yet. Mine had made a bad grinding sound ever since I bought the car (bad bearing in the alternator), but since it didn't affect charging, I never worried about it. The battery light started coming on while I was driving down the road, however, so I knew it was on its way out finally. I replaced it with a Duralast from Auto Zone. I wanted to go with a Bosch H.O. alternator, but I went with the Duralast, since it has a 100% lifetime warranty. If it ever goes bad again, I'll just go get it replaced.
