Make your own HIGH OUTPUT alternator! - Part 2: The Modifications! 

Absolutely a great vid.. perfect for the diy'er needing more current. Thank you for sharing

I need to do this on my 90/95a alt. From a acura RSX-S (honda integra).. trying to do an electric ac compressor from a prius in example install on this project of mine .. doing a honda accord k24a swap on an older model integra haha I suck at electrical work on cars

Years ago i reman'd my own alternator and the solder where i soldered the rectifier to the windings melted off about 3 days after being reinstalled and in use.....what type of solder should i have used? Gm cs130 alt

At 16:23 I did not get the type of diode referred as parts of "decent after market parts" ? Thanks for the video.

So you were saying it will put out lower voltage at low rmps how high do the rmps have to be to put out the correct voltage and the full 300 amps?

So is there any reason why you couldn’t do this to a regular 60 amp car alternator???

Excuse me for asking: if you change it from Y to delta the output voltage will be a half , right? so what is the point to change it???you will have 7.2 Volts after rectifier ...so it will not charge the battery any more.

Its really difficult to see where you cut the windings and make the connections.

Are you sure current will be 2 times higher ? Not 1.41 times higher ? Can you make measure ?

so is this possible for a denso dodge/jeep alternator ? it has 4 of those leads

how to get just 12 volts dc 60 amps I don't need very high current out of it ???? thank you bro for sharing >>>

Can u do that for a b13 sentra alternator??

OK after watching part 1 I am now aware that you are converting a star wound alternator to delta wound alternator. This means that the O/P voltage will be about a half of the original and will not be usable as a car alternator. Secondly If your intension is for wind power then the generator will be unsuitable as the high current will not be acheivable because the wind will never reach that intensity so the generator will cog and stop. So perhaps it would be helpful if you stated what exactly you hope to achieve with this modification?

Wiring an alternator in this manner (non hairpin) IS living in black and white.

Can you do that for me and how much would you charge?? I may be able to do it but I'm too lazy hahaha jk..

Hello mate,save my and give my that diagram plz 😊😊😊🛠⚙🛠

Looks like a great projet, but for newbie's like me...... need a closer look at what you're doing. Your camera is too far

Thx u for the video just wish u can make another one with a closer view plz

Yes I’d love to see a reassembly video, please. And thank you much.

I am up to about the four and a half minute mark and still haven't figured out exactly what you're doing. My semi educated guess is that you're reconnecting the stator from a Wye format to Delta. There are several problems with this "320 amp upgrade", one of which is the inability of a small case alternator to dissipate the amount of heat that it will create at that level of output. The second is that your typical passenger car/truck alternator is absolutely NOT rated for 100% duty cycle at maximum output to start with. Whatever the rating, it is with the alternator COLD. Once it begins to heat up, output goes down. Outside of going to Delta wound hairpin and/or a six phase square wire stator, I very seriously doubt that alternator is going to produce 320 amps. Even if it comes somewhat close to that output level, it won't be capable of sustaining it for more than a few minutes at most. I actually own a Leece Neville alternator originally used on a large commercial truck or bus that is rated at 320 amps....and that is a continuous rating. The alternator weighs close to 35 pounds and is 2 - 2.5x the physical size of what you're working on in the video. It also has 12 diodes(twice as many as the typical passenger vehicle alternator), with half of them mounted on the outside of the alternator.

This video series is awesome. Thanks so much for sharing makes me want to pick up a couple cheap alts and hop em up. 👍

Pls diagram alternator

Wow , awesome video. This is exactly what I need to do. I was about to buy a high output alternator because I have installed high wattage amplifiers fir audio equipment in my 2013 Toyota Corolla . I have a ?? For you, will I be able to do this to my alternator? Can you make the diagram a little more clear and also can you provide the description of the wire , soldering and all the necessary things to do the job? Thank You I love how you did this .

Yes... bro...the channel name is....THEY DONT WANT MUSIC.... so i m subscribing this channel..... Its not that we dont want music..... but when yu want to learn...electronic or motor.... that music is disturbing...... So i like this... tey dont want music channel.... 👌👌👌😁😁🤣🤣🤣... i m lovin it...😘😘😘😘😘

I would like to know how you figured this out ??? Also, how does the amp curve go from engine idle to redline ??? Does the idle RPM amperage cut in half since you went from star to delta configuration ???/ Thanks a bunch Sir too.

Hi. Great video. What about voltage regulator? Do you leave it oem? Can it handle the new field current to push 300A?

Great video! Will definitely be trying this on my tida 140amp alternator. If I was to send your the picture of the coil can you advise exactly where to cut and join on my particular alternator? Really need to do this model as my current car audio set up is in need of a high output alternator

I belive i have a 220 and i need a 320 do i only cut 1 side ? 2014 dodge ram 2500 6.7 turbo diesel

Very nice. The windings account for the magnetic force and the amps with the thickness of the wire . I’d like to see an amp clamp test to see for fun it’s interesting. What’s next

The cutting points are seriously un clear on the video . Good luck copying this , I predict plenty of flames in the community ! .

I have a Yukon with the 130 amp alternator, rpo kg8..... Can I modify my alternator the same way and double it's amp output or do I need to look for a bigger one like you use in this video? And if a bigger one is necessary, which one should I choose to modify? They have them in 10 amp increments all the way up to 200 for my year Yukon and I'm fairly certain miles ok I just need to put my Yukon "back together" again lol as it has split in half right at the "overhang of the undercarriage" lol

The top down camera view is definitely good for a big picture view but makes it kind of hard to see the fine detail of what you are actually doing to the windings..

Please use a desoldering fan with carbon filters. You have no idea how bad those flux fumes are for your health (brain).

As a qualified electronics engineer for more than 65 years I am afraid that I cannot make any sense out of both what you say or what you are doing. The mind boggles.

How much would you charge to upgrade my alternator ? 2007 single cab chevrolet colorado 2.9l

This mod will greatly reduce the low rpm output by less than half the stock unit.

What do you think about an external rectifier, the black epoxied bricks with Philip screws on top and flat heat sink bottoms?

Will it not affect anything with the new wire being 30% smaller or so than what is already on there?

Hi, I have a private question, will you provide an email

Can you do a closer up video? Thanks

What's the downside of using alternators modified this way? In the first video you said that it takes higher RPM. So I suppose using smaller pulley would help? How much should the ratio change?

I love the build would love to buy one n send you a 2005 chevy 1500 5.3l 160 amp alt into an 320 amp I liked the first parts of the video thevend was a little jumped around but I loved it I like you to build me one n do a video on it interested?

This seems like a surefire way to have your alternator overheat surely? And if it doesn't overheat then your battery will drain very quickly at low RPMs and idle?

where can I buy hairpin stators?

What if I just wanted improved rating of 20A or something, lets say from 110A to 130A, or from 90 to 120A

Good evening sir I've been watching some of your videos I would like to have link radio to assembly on the alternator also rebuilding a Ford alternator F-150 if there is one you have one and any other informational videos going along with the changing of alternators into from DC to AC output thank you so much have a blessed day

It would be better if you had drawn in paper with more elaboration on how to make the cuttings on the windings before doing it on the video. Cutting the winding is the most critical part of this project.

I would love a video, what type of information would you need from me

The comment about 3/8 killed me 😂 I hate that we use imperial here

thanks for amazing videos can I have your idea that what is the best solution to use all petrol engine HP for an electrical generator? attaches multi alternator through belt would work? OR design new specific alternator regards to engine torque and rpm

Can I send you my alternator so you could modify it?

What happens if you do damage the enamel then what do you do?

I would like to do this on a gm alternator but it is going on a 6.5 turbo diesel to compensate for aftermarket fans and lights. I have an overdrive pulley on the alternator as it is to compensate for draw at low RPM. Is there a formula to solve for what the output for my setup would be at a given RPM? I could definitely use 300 amps, but will I be able to make a usable amount of that within my engines usable RPM range?

the smartest people are always skinny

yes pleas never seen that don before grat stuff . les England

巻線の直径はいくつなんですか。320Aも流して大丈夫？

How about the original rectifier rated from factory? I suppose it needs a change as well?

I have a 200 amp alternator and I’m trying to make it 350 Is this possible

Bought a 100k mile, '06 IS250 for $9k cash, and over the past year I've spent another $3k or so on a good SQ system with all the bells and whistles. Considering the prices of 240 or 320 amp high output alternators, this video series is EXTREMELY captivating...I might just try to save myself a few hundred🤷‍♂️

Amazing job bro. Thank you for taking your time to make the video. But I do have a question for you. Can you do this to any alternator. And will it work. Or is there a different in other alternators. I wanted to modified my 2012 Honda accord alternator. Thank you for your time

Hey have a 2012 gti, using the same parts to put it back together is good? Does this change the life of the alternator?

Great video. Is there anyway to test the alternator before installation to make sure the amperage it higher and works as intended? I'd hate to go through the entire process and then install on my vehicle and it doesn't work

Hi. Great video. I would like to do this with a motorcycle stator. They look very different so I don’t know if the same rules o process applies.

You seem not too confident like youve never done this before almost like youve seen a video and are trying to do it for the 1st time

Just awesome work man. God blesses you.

buddy you're a life saver. my car the only HO alternator i can find for it is $800 and living with my budget i cant afford to spend that much plus additional speakers and another amplifier (currently have 3 10"s on a 3k thats turned down cause anymore than half power and my car stops accelerating at 2k rpms< dang 150amp alternator and electric everything lol)

I have a 2006 Scion XB that has the 80amp alternator on it and I can’t find anywhere that sales either a 240 or 320 amp alternator for that vehicle. Is it possible to rewire the alternator to get more amps out of it ?

Cool, should link pictures, I'd like to try

Good video but really hard to see exactly the cut wires where they attach to ..like the first cut one goes to the wire that's in red but the otherwise goes where? What is confusing is that don't know from diagram wich is the wire that you didn't cut but added a wire to can't distinguish wich color it is or if it's the red line blue or red ..could you explain it for me I sort of understand but just have a hard time following where do the wires go from the first cut and second cut and the spliced wire ...could you explain it to me again ...Thanks

Could you please send me a link with the pictures please? Pretty please. I'll totally sub and all that 😁

Great video and thanks for sharing. Question: What is the approximate voltage output at idle after modification?

Vera difficult to understand

This video was awesome. Thanks! Is it possible to do something similar to a motorcycle stator?

Hey by chance can you send me a link or something on the wire diagram videos awesome but can't hardly see

Thanks for sharing

what area you in ???. I'm interested in sending you a alt.. I dont have alot of time to sit down and do this you have ig? I can inbox you

You could also use insulating varnish to eliminate the bulkiness of any other type of insulation. It does require a little curing time, but well worth eliminating the other insulation. It's also generally more heat resistant.

high out put or high amps...?

Sorry this is so late being your video is 2.5 years old. But does it hurt anything to just use one portion of the stator instead of all three? I have a 5 rib pulley and it'll slip with to much load. I have a 190A alternator and just need about 250A.

I’m gonna take my SAE tools!🇺🇸on out of here and find another video

so what you mean just changing the star to delta will double the current ouput?

Heya?, I do believe he is trying to say "here".

Many thanks for your video. I have a hair pin alternator that I want to change but I see it does not look the same as the stator you worked on. Is there anyway I can send you a picture of how it looks? Yours has horizontal wire on 50% of the stator, this one has horizontal wires all the way around the top side.

this video is horrible...I can't really tell which wires are which, and it's just confusing..

Ye reassembly video please.

what size is that sleeving ?

What would happen if I tried doing this with a 90 amp alternator?

Dude I don't see a thing ur camera is far away

Yes send me some pics pictures of a reassemble on that I have or is a alternator

Hi would you be able to use your standard battery after this alteration?

Very nice jop but what is the orignal wiring I think it is two delta winding specially in dodge alternator

15:32 (Gods)

Would it be the same basic process for a ford 6g stator?

I would like a video on the assembly of an alternator please

Yup that was my truck on fire under the hood at the Bass competition!!

thanks for amazing videos can I have your idea that what is the best solution to use all petrol engine HP for an electrical generator? attaches multi alternator through belt would work? OR design new specific alternator regards to engine torque and rpm

So what if you got the 100 to 125 amp alternate can it still be done

Can get to see the wire diagram drawing. Can u put a better picture. Thanks

Hey can u do a 2001 honda accord 2.3l sedan alternator I try'd and fail there telling me I need to replace the stator and get more winding in order to even come close to that amperage.....plz plz thxs

How do I make a hairpin stator? Do you have a video?
