DC v Quick Start alternators
be still, my heart..... something to run my plasma cutter, and
Nathan K5LA amtrack horns with... not in order of importance...
For all the early 6.0 owners here, is the consensus that the engine did NOT have perhaps more 'character' than it should have during the years leading up to '06?
I did get to speak with DC today and have to say I am impressed; its an all new product with no rebuilding or remanufacturing, the cases, stator, bearings, and electronics are domestic and they also use the large case for the PSD, plus I can get the thing powder coated for just $45, which I think is a bargin-also its a mere two days out....
Quick Start did not answer the phone perhaps they are in the storm damaged areas? will keep trying.
Advantage: DC by a mile so far, or rather by twice the warranty..
Check this thread out you just might change your mind about the Cummins LOL

they have a spiffy billet one, that has a bit higher output at 225/300,
but i was told both here, and by their sales guy that the best one they
make is the 275/200 amp unit. square drawn hairpin windings, and
the best diodes they can find. it's $80 more than the pretty one. the
only difference is the square drawn wire in the stator. diodes are the
same. case is cnc machined on the pretty one, cast on the other one.
they are real people, they make an excellent product, and they stand
behind it.

GET ONE, I DID!!! lol

this is from the web page of the quickstart "high end" alternator.
"*** CAUTION *** Use extreme caution and care when installing this product. You are working with alternating current (AC), the same type current that is in the electrical outlet of your home, Alternating current can kill. Important note: The alternator does not produce AC current when the alternator is not turning. The alternator only makes Alternating Current when the motor is running. Make sure that the three AC lines that run from the alternators internal bridge rectifier to the Quicktifier are secured well insulated and covered with wire conduit to further protect against shorting out. These wires should never be allowed to touch & rub on any metal surface. If they short to the metal part of the vehicle it will send AC current through the vehicles metal components, potentially causing great damage & possible death."
after reading their website out of curiosity, i would buy the product
i currently have. my BS filter was clogged reading the quickstart stuff,
and now requires cleaning with a toothbrush.
have a nice 4th of july.
edit: after looking at their rudimentary drawing, it seems they pull 3 phase ac off the alternator windings, and send it off
to remote diodes that are ganged with the onboard diodes, to produce a composite output. what a kludge. the remote diodes
aren't fan cooled. there isn't the power density of having the diodes all in the same location, right behind the cooling fan.
and the output of 630 amps peak? what kind of interconnect wire size is being used for those remote diodes.
i bet a cheeseburger that with a load bank and a clamp on amp meter, putting a 630 amp load on this alternator
would best be done from behind a brick wall... i'm saying spattered copper. that's my read on it.
to actually transmit 630 amps, at ANY voltage, using the national electric code, and UL listings, requires
THREE 4/0 copper conductors, in parallell. now automotive use isn't bound by that, but that gives you an idea
how much copper is needed to carry that amount of current flow, continuously.
so, for example, in real world power wiring, a 630 amp single phase load would require THREE 4/0 copper conductors
in parallell... so, a total of SIX 4/0 copper conductors. it would in fact require a conduit size with an inside diameter
of exactly three inches... so the post with the 3" hole in the hood is correct..... ;-p
no sale.

I don't think you understood the part about the remote diodes being mounted on top of the hood to keep them cool. A small 3" hole is all that's needed to get the diode conductors through the sheet metal. You even get to pick where the hole goes!
fulthrotl, yes DC has gotten many good reviews, recs here but does that preclude a better product from being out there?
While any item going on sale is good, 10% just isn't enough to get me to buy today.

Just the Fact you have gotten NOWHERE with all the Phone Calls to quick start alternators would be enough for me to Forget them and go with DC power
IDK but I take it the Quick Start is the cheaper of the 2
And any electronic part can fail so it makes me wonder if you go with the quickstart and it DIES would you be in a Position to have the Truck DOWN 2-3weeks while you are trying to get in touch with Quick Start?????????
