Nice set up, would you tell us more ? What did it come out of ? What pulley did you use. What did you do about the old regulator & wiring to it ?

The alt came out of a first gen Taurus with the 3.8. $30 at a local junkyard. I had it tested and it was at about 140 amps. A little better than the stocker! With the extra lights I have and the big amp that I run it was a worth while upgrade. And not to hard on the wallet either.

I re-used the pulley off of the stock alternator.

I used this http://pa-performance.com/Scripts/prodView.asp?idproduct=75 to deal with the original regulator, but there are easier/cheaper ways to do it. If you can handle some basic wiring. I prefered the stock look of the Pa kit. This diagram will show you how simple the wiring actually is if you want to do it yourself. http://bcbroncos.com/3ginstall.pdf

You MUST use a 4 gauge wire from the alt to the battery and a LARGE 200 amp maxi fuse. I went to Pa-Performance for this too. http://www.paperformance.com/scripts/prodView.asp?idproduct=87

Hope this helps, feel free to ask any questions.

For those that want more info, you know who you are, haha!

Here's 20 pages of 3g tech and babble. http://fullsizebronco.com/forum/showthread.php?t=55169

AHHHHHHHHHH...I read that FSB thread not too long ago, not very entertaining...but very informative.

Oh and one more thing....well two.....

The "lock bolt" that holds the alt in position to keep belt tension can be an issue. Make sure you get an alt that has threads in that hole. I makes adjusting the belt a lot easier if you don't have to run two wrenches. One to hold the bolt and one to tighten the nut, all while trying to hold tension on the alt to keep the belt tight.

I also "clocked" the rear portion of the 3g. All of the wires and terminals where at what is now the top portion of the alt. Not too pretty looking with all the wires. Just pull the case half bolts out and turn the rear half where you want it and put the bolts back in. Just don't pull the halves apart, only rotate them.
