Bah ! Wive's tales !!!!

Just do the 3G conversion, the large case is old technology and huge into the bargain. It's easy, cheap and very, very effective. Cured just about all that ailed my 86 electrically.

True Soderblom has it in for the 3G, Ryan's output print outs prove the 3G works from idle up and I've had mine on for three years and it's still kicking !

I believe it was Steve83 that said you can buy the regulator kits for cheap and they can be changed fairly easily.

autozone sells the regulators for $42.


I have winched with my G3, one single 800CCA redtop. when the winch turns on the volts drop to 10 or lower if doing a long pull. It just keeps charging.

ryan in the pic of the 3 alternators mine is the style on the bottom. and of course its a 95amp. did those rigs that came with the 130amp use that style at all or where they all like pic 1 & 2.

Thanks

Ryan, kudos to you for obtaining real results. Your tests tell me the 3G does great on the RTI ramp, but it doesn't tell me how it does in the real world.

I dunno how anyone would ever do it, but I'd like to see test results immediately after both a 3G and a large-case have been made to do an identical, hard winch pull in the same engine compartment on the same motor on a 95 degree day.

It's common knowledge that heat is the enemy of basically anything electrical; as I look at a 3G and a large case it's a no-brainer to me that the large case is gonna run cooler.

I'm not sure I am following you guys. Here are some pics at this site of two 3G alternators. One is Large case, the other is not. Both are 3G. So, my 1995 3g stock is the small case. if you look at the size of the case it's obvious which is which. You can also look carefully at the holes, you will see a difference. So, for me it's just a matter of converting from the small case 95A 3g to a large case. These pics are for the newer trucks mounting pattern. Look at the pic ofthe alts. from the front. You will notice a "Y" casting with holes inside. Now, the large case has 2 large holes within each Y casting, while the small case has 4 small holes. That's how I tell.

Might work..........the fan requires a spacer so it doesn't rub the alt body, is the shaft of the 3G long enough? I'd guess not, since it was never built w an external fan. Also, I'd be a little concerned about it properly moving air into the holes (most alts w external fans have large slots)...............and doesn't the 3G have an internal fan? If so I'd wonder if the two fans would cancel each other out rather than work together.

Those are not FACTS, those are opinions!

I can get a new regulator for $25, its not hard to change it
Maybe I'll do that, just for the tech write up, and to make more FACTS

I'm not sure if the dealer would have the best price, shop around and on ebay.
That part number was on:

Thanks for the kind words.

I know the 6G alt on new Fords are controled by the computer. The computer reads the alternators temp, battery voltage, and comands the alt output. That might be able to get that kind of data.

Might just use a digital volt meter, and an inferred temp sensor.

Great link, not sure if the prices are a good deal.

From what my research has found, the small case was only 95A. The 130A alternator was only built in the large case.

I got a 3G today off of a 93 Sable. In the middle it says 130A. I also took a big chunk of the harness so hopefully I'll have enough wire to work with. I got the alternator, oil cooler w/ hose and engine attatchment, Transmision cooler, F250 Master Cylinder, Booster, power steering pump reservoir, and two T shirts today for $75 at my local Pick n Pull's half price sale. Whaaaat a bargain!!

Most places only test if the alternator is at 14volts.
Not many places can test amp output.

All the Taurus / Sable should be 130, because of the electric fan

The little center shiny aluminum piece on the back side of my alt had 130A printed on it. It looks like it would come off if any oil/solvent splashed on it.

It will be easy for you 81Bronk36

It worked great on my V-belted 86(cured a lot of problems). Do you have a double pulley on you current 2G ?

The double I had (other groove runs my air pump) didn't allow the 3G nut very far onto the 3G shaft, five threads I think.

I lived with that for almost a year and then deepened the pulley center with a lathe so the nut goes well and truly on far enough.

The reason I mention this is you need a wafer thin washer(got one at Home depot) to keep either pulley far enough away from the 3G alternator housing or it will rub. That washer makes the pulley/nut problem even worse.

If you've got access to a lathe on the base you might want to deepen the double groove pulley center almost 1/4" ahead of time.

The bottom guage is alt RPM,
looks like 6600RPM to me.
Divide by aprox 3 = 2200 engine RPM

Can the 3G be setup to run an external regulator like the large case? I had to replace the 3g (from autozone) in my truck 3 times before I swapped to the large case. Each time it was the diode that went bad. Since my coilover swap I can no longer fit the large case, and replaced it with a tiny 60A for the time being.
