Anybody out there running Dual Alternators and why? I got my new 2006 250CC with 2, I ordered it that way because I was thinking about putting a small power in it and use it while the truck was running.

 

Post pictures! I'd love to see how they mount.

Once the lease is up on my '01, I'm going to add at least a second battery and would love to run two alternators.

(Before anyone says it, I realize it's probably different between the '01 and the '05/06...)

I'll try to get some of the duallys and the 2006 Y-pipe tomorrow sometime.

Please let us know more on the dual alt set up

This is a must have for me (Amateur Radios and amps) and up to 2005 was NOT offered on the gas motrors.

I never could see a way to easily adapt the PSD dual alt set up to the V10 so now very curious how Ford did it.

Please save me the trip to a dozen dealers to try and see any V10 with dual alts by getting some pics of the setup. Please post the number on the drive belt if you can see it. Is the system mentioned in you owners manual?

Dang now you got me back into the research mode.

 

Wouldn't Ford have the brackets and stuff in their parts books?

 

Not if there is no such animal as dual alternators on a 3v V10.

I have spent the last hour on three different order guides for 2006 Ford 250-350 and all I find is the same old Option 63T that requires the diesel PSD motor.

Dual alts on a V10 is not even listed in the body builders guides for Ambulance options angin only for the PSD

OK SuperBlue, time to let us know if your dealer is yanking your chain or if you found the majic code.

 

they do offer a 200amp 3G alt that only has about 10 or 20 less amps then having two of the stock alts.

Option Code is? for a 200 amp alternator.

I can only find 115 Amp (Code 3G) as the standard alt for a 3v V10 Superduty. This is the standard alternator and exact same part number from 99 to present. Ford de-rated from 140 to 130amp for 2005 MY and from 130 to 115amp for 06 MY.

There is NO option to upgrade any charging system for the 2005/06 MY F250 F350 V10 trucks that I can find.

Come on fellows I have searched high and low for any "easy" way to add two batteries and a second alternator shy of ordering the truck with a PSD motor.

Many of the after market so called High Output alternators have the EXACTLY same stator and rotor and case configuration, they just change the regulator section. For that I am NOT willing to pay $350-$480 TO GET 180-210 AMPS.

Hmm... If I recall correctly (and that's a big IF), my window sticker on my '01 said 130 amp alt.

My '96 t-bird and '97 cougar (both 4.6L's) came with 130 amp alternator (on the window sticker).

Where's the 140 come from?

Ford has four different ratings of the alternators that can be put in the SuperDuty trucks 95, 120, 130, and 140 amp units. The 140 is only supposed to be available in the PSD versions. Most of us get the 130 as the "standard" alternator. The 120/130/140 all all identical mount and size. Many folks changed out the old 95 or 130 for the more expensive 140, some got the dealer to add the 140 by their shop as an incentive when creating a "Camper Special". A few of us are a little miffed at this crap.

The problem is that a selling point, much like the All Terrain tire issue, is the so called High Output alternator system. This is BS because you can never get the ADVERTISED output under NORMAL conditions.

Here is Fords own power out put graphs. Note that the region between 5000 and 6000 RPM is the range that a 2.72:1 pulley will spin the alt at during cruise RPM of 1900-2250.

Now you tell me where is your 130 amps? Yes Virginia, you may assume the under hood temps are normally around 200 degrees F!

Don't get me wrong Fred, I don't doubt they are definitely overrated... I was just wondering where the "140" came from when I had heard "130" for the last 10 years.

My '96 dimmed the lights at idle with everything on - 130 amps my butt.

I am one of the ripped off butt heads that "paid extra" for a high output "option" when I signed up for a $150 upgrade to 140 amp as part of a DEALER INSTALLED "Camper Special" package.

I am not the only Ford owned to be sucked in by this scam........ on the other hand (OTOH) most of the dealers were NOT ripping off the customer because they bought into the FORD ADVERTISED specs of the 95 to 140 amp alternators.

If I had known at the time that Ford's (BTW Chev and Dodge are exactly the same BS) alternators were rated for high output ONLY at low ambient temps, then I could have had the knowledge to search for a better aftermarket option. (They exist, but are hard to chase down).

Why is FRED all spun up on this issue?

The current Ford Super Duty offering is damned good BUT there are a few serious flaws.
One of the flaws and (BTW many of you suffer from the resulting problems) is that the current Battery and Charging system is BARELY adequate for all the INSTALLED systems.

You are in trouble if you modify for heavy stereo amplifier, Amateur radio loads, serious front or rear facing lights, external fuel system and pumps, and a lot of other current drawing LOADS.

Think about if folks...why are the auto guys looking at 24,36,42,and 48 volt Direct Current (VDC) systems?

Could it be that we want:
POWER every thing
XM,AM,FM,CD,MP3 and VIDEO
8 air bags
4 way ABS
on board computers
perfect engine management and transmissions logic
security systems
remote start
pre cooled or pre heated tush surfaces
auto dimming electric windows and mirrors
electric antennas, windows, seats, roofs, bed covers, curb feelers, tampon removers, and baby formula warmers.


Point is, the current electric LOAD exceeds any possible 12VDC battery system on the market.

BTW #3 if you ever do consider a 200+amp alternator because you have a SERIOUS voltage and amperage load that needs a High Output alternator...then be prepared to add a second battery or replace your single battery frequently due to increased heat and fluid loss from overcharging.

 

I agree Fred, like I said, my '96 t-bird w/a "130 amp" alternator could hardly keep up with A/c and lights on at idle. Forget putting the rear window defroster on

However, my '01 v10 SD w/a "130 amp" alternator doesn't do the same thing. It keeps up to the demand, as much as I can put on it... which has been only lights/ac/radio and an occasional very-low marine deep-cycle battery on jumper cables - which would have certainly dimmed the lights on my t-bird, but not so with my SD. I've been happy with it. The only thing I can think of is it's spinning faster on the truck motors as compared to the passenger cars and it's at least putting out a few more amps. I'll have to check now, darn it...

But you're right Fred, something is wrong.

 

Good Afternoon Gentlemen,
After reading this thread I have some concerns. I do not know to much about the mechanical aspects of these trucks. I am a little concerned about the amperage rating. I am having a Snow Plow installed on my truck next month and it appears to be a Fisher product that I am going with. Along with this I am adding strobe lights at all 4 corners and one removable one on the roof. As you are aware you are usually going at slow speeds (i.e. low rpms) while plowing and almost always at a standstill while adjusting the plow. Is this going to over tax the system? Would just a battery or an Alternator upgrade help this out? Hmm maybe I should rethink the set up after reading this. Truth be told I've only ever had GM trucks prior to this and I think thay had 200 amp alternators included with there snow plow packages from the factory.

Thanks

 

Well, my hood on my truck had been stuck closed for a while, it finally popped opened after hitting a good bump in the road. As I was very anxious to check out my dual alternators I found that I only had 1. I checked my options list that I had for ordering my truck and it was selected as an option, so I guess I will need to ask the dealer what happened.
