Alternator build
So has anyone ever used an external rectifier such as this...http://alternatorparts.com/quicktifi...rectifier.html. Im thinking of giving it a shot just wanted to know what the guys that have put a hefty electrical system on their truck think and before everyone asks why I want that many amps or tell me I dont need that much let me stop you right there and tell you I know. I just want a beastly alternator.

A place I worked for a while back had one on a service truck. It would run a HUGE inverter and would start and run a fairly large air compressor. This was a late 80's S1600 International with an IDI in it. It had a MASSIVE alternator on it. The weak point was the belts. It had a matched set of belts on it but would still slip them real easy.
If you don't ask too much of your belt, I think one would work just fine on a pickup.

I havent experienced them in person but LMC truck sells high output alternators in their 80-96 ford catalog. The highest output is either 140 or 200 amps. Only problem is they are a bit pricey.

And the fact that the wiring, especially the 200 amp 2g design, is too small for a higher output

I already have a 3g on mine. I bought it from rjm a few years ago when you could still get them. Lately Ive been wanting more since Im putting a big car audio system in my truck,Im at 1k watts now and thinking about doubling it and on top of that adding leds,electric fans, and whatever else under the sun so I was looking at upgrading the stator and rectifier to the 200amp to keep up and then I stumbled across the external rectifier and figured why not be able to run a small house. Im saving now to buy two xs power batteries but in the mean time I want to work on the alternator. Plus I dont like voltage drop no matter what I have. Then down the road if the apocalypse happens kick the subs out and run a big power inverter if I dont have one already. Go big, or go home right?

I have a little background in electronics, correct me if im wrong but this external rectifier says it doesn't add amp capacity to an existing system, it is more of an add on to keep heat down and improve life of rectifiers. (Diodes) so my question is, if you have an alternator that already is high capacity and has good quality components wouldnt an alternator with an appropriate amperage output be all you need? Just my two cents...
This quote is from the first sentence in the external rectifiers description:
IMPORTANT NOTE: The Quicktifier makes your alternator tougher it does not
boost your alternator's output to 210 amps or 420 amps.

It adds 12 more diodes at 70 amps a piece. So if you have a 200 amp alt and then add this it goes up to 600 amp. Atleast that is my understanding from what I read. I did take the liberty to email them and asked a few questions. When I hear back from them I will let you guys know if thats true or not. The alternators they sell with it say they put out 420 and 630 amps.....http://alternatorparts.com/ford-3g.html (bottom of the page)

Yeah man, I hate to say it but adding diodes to an existing alternator does not add amperage output. That is all based on the rotor/stator design. Electricity generation works on two basic principles: the strength of the magnetic field and the Relative motion of rotor to the stator. (I.e., speed) the alternators they offer are there to adequately complement their external rectifiers they sell. you can calculate all that stuff to. If you determine the total watt load at a given voltage while your truck is running it'll give you a ballpark figure on how many amps you need. Amps=watts/voltage. If youre into electrical stuff I recommend studying up on watts law and ohms law.

yeah I went back and re-read everything and looked at a few videos they have and I did mis-read it. Very confusing but I got it know. I guess its rated that high if you have a multi-alternator system which makes more sense. That was a good catch on that first line. I got so excited seeing 400 more amps and forgot my schooling.
