Modified second alternator higher voltage

[hg2]

  I saw this guys post on another forum and thought it interesting regarding being able to run higher voltage installing a second alternator modified for high voltage,and separate from the vehicles 12v system.


   Post from hhoinfo forum:

   Automotive alternators make AC at generation but are rectified into DC voltage, most are between 13.8-14.0 if the voltage regulator is removed you can get 30+ volts but not recommended because it will pop all your fuses and at worst fry your ECM, i have seen a video of a guy installing a secondary alt only connected to the cell with the regulator removed so when his vehicles engine increases in RPM it increases in voltage output, so the wattage goes up significantly from idle, kinda cool cause at those higher rpm you would need more gas to continue to see a gain. But it was a Audio alternator so that's at least 130+amps and 30 volts (this would be at max rpm and not recommend for long periods of time it will burn the diode bridge) but that's almost 4000watts of power you could make some serious freaking production with that. What i saw was a simple setup up of voltage priority switch as the other alternator make more power the stock alternator is blocked from the cell and the second alternator would take over up past 14vdc. This can also cause a problem with having the needed additional neutral plates to keep a 2.5vdc per plate avg. as the voltage increases.

its an interesting idea... but I think the guy in your post missed the point...
if you take the regulator and diodes out of the altenator and hook it directly to the Hydroxy generator that way it would work fine... if you regulated how much amps it could draw by the Electrolite... that way it would not fry the altenator...
AC or DC is still power it will still rip the molicules appart... and chances are that AC might do it even better... but that is unproven as of yet.
you wouldn't need all that extra stuff that was mentioned, think simple !
...sounds like a good idea to try to me !

  Bob how modifying an alternator that has a high amperage output to start with,so you would't have to worry about frying it and still run high amps?

Hg2:
 hat sounds like the way to go about it to me ... say a 150 or 200 amp altenator and lace the stator outputs into one line You'ed need to put Diodes in line so the power doesn't go back into the altenator coils... but that should be very do-able even by my limited knowledge.
....I don't know how high the voltage will go however... on my Motorcycle it gets as High as 90 to 100vAC... rectifying that back into DC can get tricky ...(but not if you cAN find the right components !).... but in this case we don't need to rectify it at all... let it be AC
and plug it in directly to the cell through the usual relay....
...
I'm thinking  about a 65 amp altenator I have here that the Regulator is shot on...
the one I replaced a while back on my truck that left me stranded in the middle of the night !.... I don't have to have a regulator or diode bridge for this idea... but it will need some hefty diodes from all 3 stator windings in line to keep the pulses going into the same line.....at least I think so...
...
makes me wonder what kind of power it would actually put out if you take away the junk in the way... HAHAHHA
might put out 80 amps easily ...who knows!
certainly more than the raited 65 amps as its the regulator and diodes that determan that
...( although they are usually guaged by the winding abilities too! HAHAHA)
...
tiz a interesting thought ! ....
give it a try Hg2 and let me know if it works ...if so I'll do it ! HAHAHHAHA

 Oh so I get the bill for dinner huh? You cheap old retired guys are all the same heheheheh.

bob this new alternator that I ordered for the toyota is a 150 amp and it does not have bigger windings and feels like it weighs the same as the 60 ampers that are on those trucks to begin with.

I got a upgrade kit for my alternator, makes it a dual bridge alternator, but after upgrading be sure not to forget to change the output wire to one that can handle the higher output, mine fried way out in the middle of nowhere.

It's been a while since I've been into an alternator, but if I remember right the only difference in 'many' alts is the brushes.  I say many, because you can only get so much from any given size.  Example:  the 100A alt on a HMMWV is smaller than a 200A alt, but a 80A alt on another GM is the same as a 160A.  There is a point where they have to get bigger physically, it just depends on how big it was to start with.

I know thats not funny but it still is. LOL   when I first hooked up this second alternator, I didnt hook a bigger ground up so when I started up the truck and was hooking the new amperage I was putting out to the cell, I started talking to myself  " lets see what you think about this power cell " ( you know people sick with this stuff does that sort of thing) and anyways, ground wire to my fuel pump started smoking and I am looking around feeling wires and for the life of me couldnt understand what the heck I did wrong. I looked down at that mousey little ground wire coming off the battery and knew there was more to putting a bigger alternator on than just hooking the alternator up.

I know this post hasn't been posted in in "more than 120 days" BUT! I like the topic! so.... How hard is it to take one of those suckers apart and make your own brushes and stuff, hence making yourself a bigger alternator! (everyone makes a profit so don't you think it would be cheeper to upgrade to a larger one with your own tools?). Now I don't know what it takes to work on ANY alternator (yet that is) so let me have it!

Steve !
 There are KITS available for some alternators ( Motorola & such) that allow you to up grade your standard alternator to a High amp alternator.... Randy sent me a link to a wonderful Alternator site but... I'll be hanged if I can find it now ! SORRY !
...
changing the alternator is more like changing the WIRES inside it and that is a major undertaking
things like just the brushes are simple but the wiring is another ball game completely...
I re wound a Honda Motorcycle starter Armature one time cuz I couldn't afford a new one... I'll never do that again...  If I remember right I got it working again, but it was a month long battle
and hours of tedious work....
 most alternators are made specifically for the size of wire on their windings...and if you try to replace those windings with a larger wire it simply won't fit !....(Been there done that)
but you can buy Kits that have the larger windings in them and you just replace them in your alternator and your good to go... what usually burns up in an Alternator is the Diodes or bridge rectifier.... and higher amp ones usually come in the Kit too.
...
I know Randy bought a Kit and installed it in his little Dodge's Alternator and upgraded his alternator ....apparently it works great!

Depending on how many amps your looking for, I put a
(I think) it was a 110 amp alternator my mustang. Up
from a 65 amp.  Big difference in output at idle.
It was 35.00 from a auto salvage yard.
