View Full Version : Dual Alternator Setup for 2007 Sprinters
10-10-2007, 04:01 PM
Good day everyone. I am a service center that has recently had a rash of Dodge Sprinters come through. I have seen on previous posts that there is a optional dual Alternator set up with mounting bracket. Does any one know of the MB or Chrysler part number for this bracket? Any information will be helpful, thank you.

Welcome to the forum.... but that's all I can provide; I know nothing about alternator brackets except that it's difficult to bolt the turbo resonator to the alternator bracket unless you have small hands.

I didn't find it mentioned anywhere in the order sheet. I'm not saying that it doesn't exist, just that I haven't found it yet.
Where is it mentioned?
In the part number diagram list (http://sprinter-source.com/forum/showpost.php?p=420&postcount=2)...
...it shows the bracket, but I doubt this is the bracket you're looking for. :idunno:

I assume it is the following item; PTO - Engine driven with bracket for additional alternator. 4209, thanks

The price of the bracket for the alternator and the compressor (for the rear A/C) is the same. I bet you it's the same bracket in the same location.
The two brackets at the bottom left look similar to the ribbing found on the T1N bracket.
The T1N has this bracket for the 2nd compressor. I haven't measured the mounting holes, but by the looks of the picture of the alternator, it might just mount on the same compressor bracket.

Should have done this the first time around. THis is a picture of the oil pan on a 2007 Dodge Sprinter. 4211
You can see the present Alternator mounted above the oil pan in Green, there are unused mounting bolt holes in red and yellow, the red are for the dual alternator set up and the yellow is on the front of the pan, I assume for an idler??? hope this helps anyone??

Thanks for the pic DI!

Hello Diesel Injection
Looking at your post dual alternators! and pics , where you are looking at conversions for Customers, an extra alternator for which and what purpose?
As you showed PTO references , this is where it will become obvious that this is outside of your domain as to requiring the full back up of MB to help you with installations.
You will need to log into this section for basic information . that has PDF's in a basic manual , to gain extra input then you will require to apply on-line for assistance there is a cost and MB does not accept everyone, Chrysler should be your first contact for a leading guide to let you into this portal in the full context at different levels.
ABH: Home (http://bb-infoportal.mercedes-benz.com/portal/home.0.html?&L=1&PROFILESID=07b3e5d8db426d3c90d9a585cd0e5a42)
or look for more information on this link it's easier to follow
UK NCV3 Online Operational Documentation (get it while it's hot) (http://sprinter-source.com/forum/showthread.php?t=1344)
Be aware if you do the modifications then you become the secondary Body builder, warranty's apply to your firm, not Chrysler! if a failure occurs.
Therefore you will require approval from MB to proceeded.
Part of the manual is shown as a reference
Hope this helps the unused bolt holes are for extra lines for a cooler front radiator and the retrofitting of an extra oil pump that is used in conjunction with the PTO ! depending on type and use of the unit.
I have all year manuals long versions but can not download as to the size of the file, however these are free for use to download.
Note they are for reference only, this is where you require further on-line one to one guidance.
Have a great day Richard

I am unfortunately only the service writer on these projects so in no way am I technical. These Sprinters are retrofitted with equipment for sewer pipe inspections basically, the sheer amount of power needed to run the equipment in the van and the video equipped runner in the sewer is far more than even the 220A option can handle. I can see in your last reply the additional equipment and equipment carrier, this is basically the option we are looking for. I have talked with five different UK specialists that DC AG passed me off to and they were extremely helpful but had no ideas, and of course any dealer in the US is completely clueless to the Sprinter Model.
10-11-2007, 02:52 PM
OK I see your point The question is as you quoted ! Sprinter owners are asking for an additional alternator , I assume to run extra gear?
This is common even down under, just as an example a guy goes to a shop who does RV fit-outs says I want extra power, My question would be for what purpose? conversions costs thousands of dollars and playing with electronics ! You do not cut and shut with wiring on a sprinter.
If for example it was for a TV crew Now your looking at over 100 thousand dollars to convert and the sprinter is perfect for it.
This is where if a private company wants to be involved in fitting out one of these vans , the company must be prepared to invest in R&D to develop a system custom for a one of project that may be similar to other projects with variations etc
Telescopic towers satellite camera high powered TV direct linking to main frame computers etc all involves the MB portal for on-line help. MB has invested billions of dollars f for this purpose, the Technological Intellectual rights have a cost. MB UK has to pay for the license , for you to be involved Partnerships are closely aliened with both companies share the intellectual technology and rights it can be very profitable for a US company to be involved if you have a Market.
To start , you need a tech who is qualified to do the on board electronics that has the star diagnostic equipment to code up the electronics and or activate many of the systems on the Mercedes Sprinter, you need an engineer for body alterations this must be presented to MB for a compliance of acceptance as to center of balance, if you were to install a 30 Ft antenna the front axles needs to be changed to at least 2300KG rear needs to be altered as well, compressors PTOs all have a part to lay depending on your requiremnets.... The list of alternatives are as long as the thread could run if that made sense.
In defense of your last comment No dealer seems to have a clue, I would have to agree with you,It is as if Chrysler just wants the Sprinters to disappear, but they will not because Chrysler Ford and GM simply can not invest in the billions required to build new platforms from scratch they can not keep on applying for exemptions investments must come from overseas it's as simple as that and the US mangers just bury their heads in the sand.
IF you have a company with the resources and capability's to do this , then start now, plan your strategy's for future development and make the first step to doing it, by having a board meting to implement the procedure,and you will not look back if your plan it well.
I would approach AG in Aubin Hills first , have a chat and this will be the start towards the path you desire.
Break the van down to three components Body modifications, Engine management Electronics , find sources for generators alternators that are compatible, for the sprinters, don't be afraid to ask Euro managers many will give free advise and leads, you could also look at air suspension from VB for emergency and disability vehicles your sitting on a gold mine if you can put a business plan together,
Now Diesel Injection: This is the time to start, the US economy will turn...at the moment you have two year window frame to take advantage of your competition.
Think out side of the square if you want to make real money. if your development is two years in advance of any one else you have the advantage of being the Market leader in a not so competative game plan,

Why would I need to figure out the on board electronics if I wanted to hook up a second alternator?
The mechanical part should be trivial. Buy the mechanical parts (ie., brackets, alternator, belt), and install them. The design of the Sprinter should have provisions for that. Probably not that easy, but it shouldn't be that hard. :bounce:
As for the electrical part, I would just attach the output of the 2nd alternator (with the necessary transformer/regulator :professor:) to whatever I want to power, using batteries as buffers. There's no reason to tap into the Sprinter electronics to do this. You can either float the GND or attach it to the chassis to create a common GND.

You can either float the GND or
What does "float the ground" mean?

What does "float the ground" mean?
Jon...The GND, normally the battery negative of the 2nd alternator after it has been converted to DC, is not connected (isolated) to the Sprinter battery negative. It essentially floats or is isolated.
The only thing is the 2nd alternator's body is connected to the engine, which is the Sprinter battery GND (negative). Installer just needs to be aware that they need to order an alternator that has an isolated frame.

Altered Sprinter - This is something we as a company have done for years. Mostly with the 2003 model MB and Dodge's. there is a company in our neck of the woods that sends us units from around the region/country to install the invertor/electronic components in these units. We have created our own mounting and install kit and done the R&D for this and other GMC workhorse models. This new 2007 Dodge comes in with these strange mounting bolts. as my picture illustrated it has solved (presumably) our mounting situation with the older models. Yes, the R&D to get a dual alternator set was costly.

Just picked up the 2008 Sprinter brochure. On the inside of the back cover, under performance/functional is an option for an auxilary belt drive for auxilary alternator. Not available with the 3.5l gas engine. Not available for the passenger van.

I have spoken with a Daimler Chrysler rep, and this may have to do with previous post. There is a spec/update comming out in the next few days addressing this very issue. thanks for all of the help in this I will post what I recieve once I get it.
10-16-2007, 10:32 AM
do you have any idea, which qualified companies can install a 2nd 24V generator in Germany?

D.I. I have a 2005 sprinter and am very interested in the dual alternator setup is this something you can help with
