Right now I have the factory 136 amp alternator but I'd like to get it rewound so it has a higher output. In other words I'd like to avoid buying a new alternator if possible. So I'm trying to figure out whether or not the case is big enough to do this? Thanks in advance.
 
the local shop here said "there is no room to add copper"
2 options
a smaller pulley to make higher rpms=more power
more cooper... duh...
(mean green alt i have has flattened copper(think - feta-chine pasta/more inside than standard one) and a hair smaller pulley, hence more amps at idle and way more at 1800 rpm
 
If you would like, next week when I get back to the office, I know a shop in IL I think that the owner is a true electrical guru extrodinare and he just authored a short article on how he seriously upgraded the output on a Ford. This guy knows his stuff, he writes articles on a regular basis for a trade publication, he finds the problems. I could PM you his info, you could follow up. They fix the unfixable electrical situations. Let me know.
 
prarie dog-chicken lights, auxillary lights, an 800 watt amp, and a 2000 watt amp, and trailer lights=yes

jfought- makes sense, i'm getting ready to start constructing my onboard air system with a york compressor so if i was gonna change the pulley that would be the time to do it.

gcroyle- yes that sounds great, i appreciate it.
 
I believe there is a 180 amp alternator that will fit the mount. Not sure how to ask for that part number though. :confused:

I have spoken with this gentlemen before... He will clearly state . . Amps are NOT the Problem,almost all automotive charging systems are designed to keep a charge. . NOT continually make a charge. Timeless if you like call Me. . I am done posting solution(s) here at the TDR.
 
I'm not making any claim of unique knowledge to the OP's question, merely offering to start a connection to an automotive electrical specialist who lives fixing electrical problems/challanges/unique requests.
 
I here Ya GCroyle. . AND if Memory serve Me. . he knows exactly whats needed to boost systems WITHOUT Burning down the host. I have Personally burn down 1 Ford and Melted wiring on 2 Dodges I have owned, modding the systems to Run our electric hoist on all our lifts for My Construction Business,My mods required different approach then the OP WANTS. YOU can have fire real Fast if YOU don't WTH your doing.
 
That's a good point Todd, can that puny wire (8awg ?) really handle that much more current? Seems like upgrading the charge wire may be required if it's to efficiently carry another 40+ amps. Otherwise that current may just be turned into heat.
 
yeah, i saw where geno's had a 180amp alt. I upgraded my charge wire coming off the alt to 0 gauge o2 free cable, and have upgraded most of the ground straps to 2 gauge, in addition to adding ground straps. My original thought was just to add another battery but i was told that that was not the proper solution. so any and all help is greatly appreciated.
 
I think EMS type vehicles use high output alternator systems or maybe two of them? Maybe research this route.

I have been trying to find a VIN number from a EMS Dodge with the 6. 7 Cummins to see if the alternator charging wire is different from the stock 6. 7 alternator wire. From what I could find out, the 5. 9 engines did not have the 200 amp alternator for the EMS trucks. If anyone has access to a 6. 7 EMS truck, check the back of the alternator for the amp rating. If its the high amp (stock is 136 amps) get the VIN and see if the charging wire is different from a stock 6. 7. The charging wire has a fuseable link in it. I can't seem to find anyone that knows it's amp rating. Oo.
