Do any of you guys have dual alternators?

Oh ....and wouldn't it work to mount a 9000 watt generator in the bed????

lol nice that guy is running a huge cb amp

the 3g is 3rd gen of ford alterantors

its found on the 90s and early 2000s taurus
you want the 130 amp unit this will have 2 holes between the stiffening ribs
they are also on the 300 6 vans with ac but thats hard to find in a yard
there is a techa rticle on it
the wiring is the hardest part and that is still easy
it will bolt into your sotck alts position just swap the pulley

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.

you will also need to run a second vbelt to get anything over 85ish amps. 1 belt will slip around that load. Luckily i already have a double vbelt pulley. i think all of that is in the article above

 

[Wicked97]

Well talk about jinxing myself. I post this thread and now have a dead alt or regulator or both.

 

[79jasper]

And to think if you had duals alts, you'd have a backup....

 

['94IDITurbo7.3]

the 3g came factory on OBS truck iirc.

 

[Dave 001]

If you are refering to the second groove for the vacuum pump belt......that pulley won't work. The V belt grooves are two diferent sizes, so you can't run belts in parallel.

Besides if you use the second groove for a dual belt setup, how are you going to drive the vacuum pump?

You're right, but it was only the small case (95 amp).

You can find dozens od large cases in the salvage yards on Taurus/Sable cars.

 

[Wicked97]

Well time to dig through the pile of parts and do the 3g swap. The regulator and alternator and toast. I think I have a couple laying around. I just have to pick up the regulator plug when oreillys opens tomorrow.

 

[79jasper]

Doesn't the 3G have an internal regulator?
Or am I thinking of something else?

 

[Wicked97]

Yes they do. My truck is the original externally regulated 100 amp stuff which all took a big dump.

 

[79jasper]

What I was getting at I guess is, can't you delete the external regulator once you get the 3G in?

 

[Wicked97]

Yeah that's one of the benefits.

 

[79jasper]

That's what I was thinking. Just wasn't completely sure since you mentioned buying a new regulator plug.
