Lightbulb 3G alternator FACTS (its wins agian!)

Here is the alternator tester my professional uses:

http://www.oldfuelinjection.com/publ...lt-tester2.jpg
The RPM on this machine is at the alternator. To get engine RPM:
engine speed (multiply by) crank pulley diameter (divide by) alt pulley diameter.

This 3G seen above came from a junkyard for $20
At IDLE it cranked out more than 100AMPS


It MAXED out at 135AMPS


The last junkyard 3G alternator I had tested cranked out 150AMPS max
My personal 3G cranks out 165AMPS max.
This is what a 200A 3G will do:


I don't care what other people and internet sites say about the 3G alternators, or what claims they make about other alternators. As far as I know I'm the only person to publish the actual testing.

Those are the facts as I know it. Prove me wrong, or shut up

You're preaching to the converted Ryan !

Nice work on the photos ! I'd say the 3G swap was the single best mod I've done to my 86 ...period.

It was also a virtual bolt on for us V-belters.

Nice to see the proof though

Bronco Info: 79 460 6" coming soon...39.5s, D60/D60 ARB/Detroit w/ 4.88s
ford taurus too. like 90s or so. goto the parts store, have them look it up & open the box. then the yards will have miles of tauruses to choose from. honestly this 3G isnt going to put out too much more than my large case will. i just hope it will last longer than the last 4 large case units i had to swap out

take a look at TRUCK my 79 custom. 6" front, 4" rear, 460, 37s, 8 lug conversion. F&R discs. this season, i will have the D60/D60 installed, rear detroit and front ARB with 4.88s and 39.5 IROKs on hummer double bealocks, hydro assist and crossover steering

This is what my research last week yielded Andy:
94-96 Mustang V6
95-96 Windstar V6
94-95 Mustang 5.0
94-96 Thunderbird 3.8 V6 non SC
93-96 E/F series trucks vans 4.9L V6

If you want to buy one right from da zone the PN for a Duralast is from a 94 Mustang PN: DL7734 It's something like a $40 core though. I'm gonna try and find one in a bone yard.

Bronco Info: rusty
The $20 alternator testsed above was from a 1990-95 Ford Taurus 3.8L

All of these Ford vehicles had the 130amp 3G

(1994-95) Ford Mustang 5.0L
(1994-00) Ford Mustang 3.8L
(1994-97) Ford Thunderbird, Mercury Cougar 3.8L
(1990-95) Ford Taurus, Mercury Sable 3.8L
(1993-99) Ford Taurus, Mercury Sable 3.0L
(1995-98) Ford Windstar 3.8L & 3.0L
(1991-94) Lincoln Continental 3.8L
(1992-97) Ford F Series Pickup
(1992-96) Ford E Series Van

Be carefull there was a 95amp 3G, it's ok, but not high-power
Most of the 130amp 3G's will crank out 140-160amps.
there are about 6 different mounting styles. 2 are good:
The first picture shown will fit the early Serp belt trucks and older V-belt trucks

The second picture shown will only fit the V-belt trucks well. you can fab some exxtra brackets and force it to fit the early serp belt systems, but it's not pretty.

The 3rd picture came stock on the later serp-belt trucks. However most were 95amps stock.

Ford part # F6UU-10300-FA is a 130amp 3G alternator that will fit the later serp trucks.
Last I checked dealer cost was over $225, shop around and on eBay or Ford Fuel Injection.
That part number was on:
(1997-03) Ford E Series Van, F Series Pickup 4.2L
(1995-01) Ford Explorer, Ford Ranger 4.0L

Ryan, when you say be careful, there was a a 95amp alt..How can you tell the difference, between that one and the 130? I'm assuming the 95amp can be found in those models you listed as well??

Ryan,
I have a quick question for you our anyone else that would know.
I have a 93 5.8 bko with the stock alt. I pulled an alt of the shelf for a 93 e350 5.8 with the 130 amp option and set it next the bko alt and they looked exactly the same. The question i have is wouldnt this be a direct replacement for mine except for maybe a extra cable from alt to battery to hold the extra current. All of the other plug ins look the same. Thanks tom

Make sure your wiring is up to the test first. An inline fuse is a good idea also.

One simple fact... the 3G alts do NOT hold up to off-road use. Ask anyone who wheels in muddy/dusty environments and they'll tell you that they've gone through several 3G alts.
