130 Amp 3G Alternator Upgrade - Easier than 2 alternators !

Because the electric fan I am going to be using in our Gremlin has a 30 amp draw and I plan on other upgrades like a stereo and maybe a upgraded ignition, I knew my 40 amp alternator wasn't going to be able to keep up so I have upgraded to a 3rd generation ( 3G ) 130 amp alternator. If anyone is interested in doing this conversion too, PM or e-mail me and I can set you up with an alternator and wiring. It can also be installed with a single pulley or as pictured with a double pulley. I see several posts here about people adding a second alternator. This setup makes more power than 2 factory AMC alternators.

Theres another alt. that will work in place if the stock AMC. It's from a 87 El Camino with a 6cyl, 93 amp GM only 60 sum bucks from Advance Auto or a lil bit more from NAPA but Auto Zone was like 90 for some odd reason :-| Dont forget they all price match but one thing you have to do to the alt is to take the 4 bolts the hold the "halves" together and twist it 180 degrees to get the wires to the top posistion and its all gravy!

A0M797X112187 - if you have some more pics and info please email me at vic.b@shaw.ca THANKS!


76-cj7 - interesting info, i will see if this works, might be able to get a good alt for cheap.

I am using a 140amp aftermarket and a stock delco 60amp alternator and I like having the backup if one should die I just flip a switch and go back to work.

I found the wiring for one of these 3G's at http://www.bcbroncos.com/3ginstall.pdf
for anyone interested. The only change that looks like you would need is the pulley and maybe some bracket work

Interesting ... 76 if you have a site or spec's for the ALT go ahead and post them up :t:

Ironman - does that ALT have the internal regulator?

I've got dual E-fans on the CJ and also want some tunes and extra lights to go along with the 12K winch and (soon) dual Optimas.

i think its internal. look at the diagram in the link. its wired similar to the 10si.

Bump. Does anyone have the info from A0M797X112187? This looks like a perfect upgrade for me.

search google for the 3g wiring diagram. Its wired almost the same as the gm alternators.
