I finalized the order yesterday. The ordering guy calls me and leaves me a message the 8X5 dual alts came back from GM a no go. It accepted it right then and there on his computer link when I was there. He's off today so I thought I'd run it by you guys. My question is: Are the dual alts a conflict because I didn't order Z82 trailering and the UY2 camper wiring bundle? All these trucks have the 7 lead harness and seperate fuses under the hood. I'm gonna put on a Putnam 15000lb hitch so I didn't want the GM tube style hitch and the 7 pin plug for $180 cost. Am I going to have to get Z82/UY2 to get the dual alts accepted on the build order? This is my thinking...or have they made dual alts standard with the LLY as F**d has with the 6.0 powerchoke? Or perhaps is it excluded because a 145 amp or higher single alt (I think the high output is 160 amps now) is included with D-Max (because of dual batts)? I have a fisher MM II plow, and a 210 amp charging system could only be a good thing!

Rippem,


I had the same problem when ordering mine a couple of weeks ago. It was not listed as an option and still isn't on the GMC build your own site. Several other posters gave me the code and I spoke to my salesman about it. He stated that if he pulled the order to change it, I could loose several weeks getting back in the build order. I ended up leaving it alone and will add the duals alternators at a later date.


Here is the link to the other thread with the option codes...

Thanks for the info. We found it under specials, and put it in the build from the get go...but it has been rejected/excluded whatever. I just can't figure why?

There can be MANY reasons for this.


As a former Ford Motor employee that dealt with production and distribution on a daily basis I have seen many reasons for options not being available. The industry calls this "commodities". Options take rates are never predicted perfectly and often results in excess supply or a shortage. This is a popular reason but there are many others. The supplier that makes the part can't keep up with demand. The engineers are or have redesigned the part and THEN the supplier has to make the adjustment. Sometimes there is only a limited amount of an option to go around. When that's the case the dealer can only roll the dice and hope the vehicle he has in the order bank is chosen for production WITH the options chosen.


You get the idea.....


Bottom line, there is always some reason. Frustrating as it may be.

I,m guessing you got the snow plow prep package which includes the 145 amp alternator so maybe that conflicts with the dual alt option. Try deleting the snop plow prep and see what happens.


You could always add a second alternator later like I did a Powermaster 200 amp plus the factory 105 amp makes working the plow no problem.


And the volt meter dosent even stop at 9 volts when the truck first starts up anymore. Straight to 14 volts.

Well the plow prep thing makes some sense. I have always ordered my trucks w/ VYU plow prep, because of all the goodies you get in that option for the price. Unfortunately VYU is not available on CC and/or CC with D-MAX, even though some sites will say it is, you CANNOT get a CC diesel with plow prep. http://www.dieselplace.com/forum/smileys/Cry.gif O.K. so I feel the plow prep is not available for two reasons...#1 is front axle weight rating with D-MAX, #2 is that the heavier torsion bars, coolers ect are in a D-MAX build. You don't get the light bar switch on the dash or the easy to tap front end lights, and the NZZ skid plates are available seperately. Is the 145 (160 now) amp "high output" alternator that is also part of plow prep...standard with a dual battery diesel build? It should be, I hope so, 'cause one 105 amp doesn't cut it! That's why I was after the dual 105's (210 amp system) was for the charging capacity. I just feel the exclusion I'm getting on my order is option combination related...not lack of supply. I just want to make the changes to get them in the build ASAP. At $194 in the build...it's a deal. No doubt twice that out of pocket aftermarket! I'll post the reasoning for the exclusion when I get to the bottom of it. http://www.dieselplace.com/forum/smileys/Wink.gif

Dual alts arent standard on the 6.0L Ford. I had to order mine as an option. As far as them being standard on the LLY, they are not either. My new LLY has only one. The output isnt even listed on the window sticker.

Here is your answer:


8X5 Alternators, dual 105 amp (MSRP =$224.00)
Provides 210 amps total alternator power from a dual 105 amp alternator system.
1 - Requires RPO (LLY) Engine, Duramax 6600 6.6L Turbo Diesel V8. Not available with RPO (VYU) Snow plow prep package.

I got the dual alts on my LLY made in Feb 04, but did include the trailer pkgs.


BTW, I changed my color early on after ordering and did experience a two week delay in manufacture. But there's no question I made the right choice. If you want to change your order on something, remember you'll have the truck a lot longer than two weeks. Don't let a salesman talk you out of a change you really want.

Thats not his answer.

HE didn't (can't) order the VYU package.

I would go ahead and order the trailering package. That must be whats holding back the Dual Alts. Heck, I've NEVER seen a pickup on the lot WITHOUT a reciever. You'd think they were standard.

With the towing package you get the fully wired trailer plug receptacle (almost worth it right there!), and the reciever. You'll be replacing the reciever....Sell it on Ebay! And put your HD one on.

My 04.5 Ext Cab truck has the following LLY, VYU, UY2,Z82 and I don't have the dual alternators. I was looking it over the other day and was wondering why I didn't get them either. I find where the belt idler and 2nd alternator go but it's empty.

That information is direct from the SEO Dealer order guide and the RPO information is the same for Chevy and GMC. I would have your dealer call GM. You can even call them yourself at 1-800-222-1020. I must have call them a dozen times before I placed my order and always was give answers, they even called me back after looking into some hard questions I had. Edited by: Voodoo

You guys are all over this http://www.dieselplace.com/forum/smileys/Clap.gif...thanks! Here's the word this morning, "the dual alt option is on restriction for fleet orders only". I asked about the lack of trailering/camper wiring options and my ordering guy says he talked to the rep and it doesn't make a difference..."restricted to fleet orders only". Is this gospel? I have my doubts...but don't want to take any chances of holding up the truck. Maybe I'll go over thier heads and call the 800 # for a little more peace of mind that I really can't get them. Soooo....anyone know if one 145/(160) amp alt is standard w/D-MAX? You would think the single high output alternator would be part of the dual battery setup?

Rippem


I guess they were selling to many dual alt setups and couldnt keep up with demand so now there restricted like you said.


I'm pretty sure the high output 145/160 amp is NOT standard with the Duramax unless they changed it for 04. The standard alt that the rest of us have are the 105 amp alt. Some have a 130 amp upgrade and some with 145 amp snow package. But those are upgrades. Don't know why they make such a small alt standard for a dual batt set up but they do. Guess once the truck is running the 105 can handle all the electrical acc.


So if I were you and couldn't get the dual set up or the snow package 145 amp I would see if I could get the 130 amp upgrade and just add the second later. Yes it's more expensive I paid $350 for the Powermaster plus about $75 for the brackets and new belt and pulley. But I'm a happy camper nowhttp://www.dieselplace.com/forum/smileys/Big Smile.gif


Also I would reconsider the trailer and camper options there cheap options compared to the rest of the truck and there worth it just for the wiring thats done for you. Plus when you get an electric brake controller it just plugs right in under the dash and your DONE. Your wiring is finished and correct and fused and again a happy camperhttp://www.dieselplace.com/forum/smileys/Big Smile.gif And as was mentioned you could always sell the factory hitch if you want to upgrade to a heavier one. Or donate it to a Furd owner it would be considered HEAVY DUTY for themhttp://www.dieselplace.com/forum/smileys/Wink.gif

WOW, I can't believe GM would pull this crap, you guys need to stick to your guns, let GM know that holding back on your option choice will force you to go elsewhere for a truck. This is the only thing they know is money. Call the 1-800 number and raise hell.

OFF topic a little,


If one of the alts went out, how would you know?

I could probablly tell by how quick the voltage comes back up to normal in the morning after start.


1 Alt and it would usually hang at 10 volts for about 15 sec then up to 14 volts


2 alt and it never stops at 10 volts, straight up to 14 volts.


If you wanted to test you could just pull the wire feeding the alt and see if your still running at 14 volts off the other and vice versa.


If your running down the road you probablly wouldn't notice because 1 alt can keep up with normal electrical loads.


Maybe the computer could tell if 1 quits and turns on the batt light.


My .02 Diesel Dragon http://www.dieselplace.com/forum/smileys/Cool.gif

Just wondered if there was a sensor for each alt, that would trigger a light or DIC?

How about this 200 amp alt on ebay
