OK, FINALLY found a 160a Durango alternator. Looks like it will be a real simple install. Just want to make sure I have it right.

The large stud is, of course, the positive to the battery. The small plug is the field, right? Field polarity, AFAIK, does not matter, correct?

And thats it.

Now I just have to come up with some type of connector for the field wiring plug.

Go back with a pair of clippers and get the plug.

You are correct in that you can hook up our field terminals either way.

Wow. Why do you need such a big alternator? Big stereo system?

That's got to draw quite a bit of power off the crank.

No can do. Had to order this one. Looked in EVERY yard within 45 minutes of home. The ONE I found, I wasn't about to pay $125 for USED!!

Thank you sir!!

Yes, see my other thread re: HO Alternator for details. I currently cannot run headlights, AC, and stereo without dropping below 13 volts.


NEW question: Can anyone confirm that this alt is EXTERNALLY REGULATED?

If you don't know if that thing is externally regulated don't install it yet. I'm sure you know that though.

Yes, I know that the wiring will depend on if it is internal or external. I'm diggin through my links now trying to find where I decided this was going to work. LOL.

Frick. Not having any luck. I find these installed on several Jeeps (on Jeep forums) but I don't find any mention of internal or externallly regulated. Hmmm...

If it's external, I use my current field wires from the SBEC.

If it's internal, it just needs a switched voltage sense wire.

Still searching......

Although your link bounces me to the NAPA home page and asks me to select my nearest store, I'll take your word for it!! Thank you.

Dakotas/Durangos charging system is regulated by the PCM.

just in case you wanted to see it fr your self. just look up the alternator (2004 durango?) look for the 160 and it'll show a description about the alternator.

OK, installed and working GREAT!! Absolutely night and day difference when pulling down the electrical system - headlights, heater, stereo. Factory volt gauge barely fluctuates now, where it used to drop to nearly battery voltage.

Top is the 160 Durango alt. Bottom is the stock alt.

The field wiring is simple. Couple of crimp connectors fit right in.

http://i194.photobucket.com/albums/z136/wevie0037/BackCrimpsTwo.jpg

I was going to change the pulleys, but the Durango pulley is a smaller diameter. That means faster alt RPMs which should give better idle output.

It may not look it here, but the difference in diameter is substantial!

http://i194.photobucket.com/albums/z136/wevie0037/DualFront.jpg

The Durango pulley is much wider - I think it has two extra ribs. The stock belt fits just fine, just don't use the outer two ribs on the pulley.

Here you can see the width difference. Only problem this causes is the AC belt, when fully tensioned, interferes. I'm going to try a shorter AC belt to see if I can tension it up.

http://i194.photobucket.com/albums/z136/wevie0037/DualSideTwo.jpg

The smaller pulley also made it impossible to tension the alt belt with the stock mount. I simple extended the "dogbone" piece about an inch.

http://i194.photobucket.com/albums/z136/wevie0037/BracketExtension.jpg

You get the idea there, although thats not the final piece.

For the wiring, I simply cut off the plastic piece with all the wires in it at the factory alt. The two small wires (field wires) went in to the aforementioned crimps connectors. The factory hot wire was retained using a crimp to fit the 8mm stud on the new alt. The factory ground wire I put a ring crimp on and attached to the lower alt mount on the alt side.

Looks good.

A shorter belt would have also fixed the problem with the tensioner. :)

It looks like it might also be possible to use that alternator as an upgrade to the 2.4l stratus unit.

The 160amp unit seems like a bit of overkill but if it makes you happy then go for it. :)

Parts store moron was no help in locating a shorter alt belt.

I thought of this a few years ago, unfortunately never got a chance to try it on my daytona, you are correct, it is externally regulated, mad props to getting it working on the older cars, I was gonna swap pulleys. Got mine from www.car-part.com for $50 shipped! The plug pn is 5019925AA but like $40 list, you can also cut one off about any ram/dakota at the jy, the rams also came with a 136a nippo case for anyone who doesnt need 160a but want an alt bigger than 90a. It has been working great on my 96 intrepid for about 6 mths now.

here is the pn for anyone who wants to try to scavenge one

Sorry for phone pics, they came on about 01 Durangos with the firetruck package, 5.9 engine ONLY

Yep. Got mine from car-part for $45 shipped to my door. No wire tail, though. I was also planning on swapping pulleys until I saw the small diameter that it came with!

If it was internally regulated, wouldn't it be a 1 wire only alternator? No sense in having field wires if its controlled internally.

IF it were internal, I think you would need the charge wire and the sense wire. Plus a ground, of course, since the brainy injunears mounted our alts in rubber bushings.
