Jay, Your the first and only person to fully explain how to wire an alternator !! I must have watched 20 to 25 videos on this until I came to yours. Thanks so much for the info !!!

[@brentmack51]

Agree best explanation ever

[@pauldebenham5543]

I'm the same as Ken below watched loads of crappy long videos just trying to find the info you gave us in minutes thanks bro, Paul from UK

[@DNoil-pf5uc]

May god bless this man....he totally helped my solve the problem on my 1972 Impala!

[@BensMiniToons]

The Alternator on my ford 8n hasn't worked in years. Its missing the exciter wire. This is the only video that explained it well enough.

[@tynandill926]

Huh 🤔...Great explaining, this may have solved my alternator overcharging my battery and battery not taking a charge and staying dead after shut off...in my '84 Monte Carlo with a 305 1st Gen SBC, everytime I shut the car off my battery is dead and I need a jump. After a jump and about 5-10 minutes of driving, my dash lights, headlights, and stereo slowly dim and eventually power off completely, but my HEI distributor doesn't power off, I'm guessing running from the alternator as you stated about the ignition coil. I have a C130 which originally came with a 3 wire plug and idiot light. I was told a 2 wire plug was less complicated. So I bought a 2 wire connector and I wired it up exactly how you did with the 10si alternator you have, S wire to the alternator B+ stud, and exciter wire to the ignition port behind the firewall in the cab. I think it's the cause of my alternator overpowering my battery, I get 15.5 at the alternator and battery with the engine running. I say that, because with the C130 in your video, you have the 3 prong connector with just the single wire, that being the exciter wire itself...vs...mine having technically two S wires, the external wire from the 2 wire connector and the internal S wire within the CS130...or does the internal S source of the CS130 only work with the 1 wire connector ? 1 wire connector looks even less complicated than the 2 wire connector and you're showing and telling me that the 1 wire connector is the correct connector I need for my CS130 Alternator. I need a 1 wire connector for my CS130 alternator.

[@joshualjohnson]

Awesome video. I have done several alternators but not frequently and always forget which wire does what. This is the best video and most to the point I’ve found. I’m sure I’ll refer to this video several times.

[@Joe-xj2tb]

In two mins you answered all i needed to know thank you sir

[@madsardthung6892]

This is very basics and very important valuable knowlegde, straight forward explaination and easy to understand.. It's really helpful!! Thank you shared your video.

[@TeamAustinn]

This really helped! I had bought an alternator with a similar set up to the first one you showed and I was wondering how I should go about hooking it up. Thanks a lot!

[@jonbigeffortthegoodness7437]

An alternator (wired specifically, is an electric motor and my bike is an e-bike

[@davidiverson2541]

I really appreciate your video. It clarified where the alternator output wire goes. Thanks for posting.

[@roosterup2706]

I appreciate your advice. I was lost on my backyard project but I think I can get it going now. Great video.

[@jonathanolsen7254]

Thanks for this video, I have a 2 wire alternator from a 63 chevy small block, the motor is mounted on my run stand, I see that on the back of the alternator there is a wire that goes to the "+" side of the batt, on the white wire that you have where does go to. Big thanks...

[@benferguson4629]

Thanks for posting this. I hope these instructions apply to the ACDelco 335-1222.

[@relaxbecalm5574]

I found out about the diode after starting the car I was redoing and had not put the whole exhaust system on with only open headers. I was standing in front of the car and ask my friend to shut it off ...the second time I ask him he held the keys up and said I already did lol. Live and learn. You need a diode in your back turn signal lights also when wiring an old school turn signal on the column or you end up with flasher when turning

[@Joe-xj2tb]

I thought i was the only one however it appears i have been mistaken much respect thank you sir

[@entinipikire2977]

I have a 70 amps alternator what type of diode is recommended??

[@miguelcontrerasflores8109]

Hello, thanks in advance. Sr. I just wonder where the white cable is connected?

[@RiversidewoodFarm-vq3bl]

Simple and to the point!

[@CuringDaHOOD]

Thanks for the video. Can you tell me where I can order the one wire diode alternator wire?

[@Windturbinebod]

Very Informative & Useful Thanks Dude!.

[@rahulmitusing5225]

Wow thanks alot for explaining how to wire an alternator it really helped me I had purchased an alternator and I was wondering how do I go about connecting it just a quick question what size diode did you use as I also need to fit one cause my system is overcharging please help

[@larryalexander4833]

Diode isn't to regulate the charge rate. Just to regulate electric flow direction. Your external or internal regulater is possibly bad.

[@whatisdreup2]

I see an extra bolt on the back side of both alternators, will that be where u hook up your negative cable to the body of the car?

[@ChrisFlims405]

If it doesn’t have a good ground will that cause it to die when I take it off the jumper cables

[@MPDano]

Great video but how do you know which one of the 2 spades is a sense wire? I have a 2 terminal in a T shape.

[@scottschmittmusic]

Can I plug the left alternator white excite wire to the pos side of coil

Can i hook this up to a small block mopar somehow, need to be creative wih making brackets i guess

[@RobertoTapia-h5k]

I like your videos very helpful

[@RaviYadav-nx7ft]

Hi can you make wiring diagram for dummy light and explain how it's works and if I want to put extra light to Indicate for my alternator charging how can I wire . Thanks a lot if you can do this.

[@josephsmith2561]

So the white wire keeps the coil hot. I am working on a diesel tractor. Where would white wire go since there is no coil?

[@jb-ik8sj]

So does the alt have to stay excited all the time? Would it hurt the alt of the excite wire was hot all the time? Even when the motor is off?

[@larry1861]

But what if I'm hooking up a a battery isolator do I still need the wire with the diode ?

[@BOSSDIGS]

I follow your blog sir. Thank for 💡

[@MrTruetoform]

Thank you for making this easy to explain.

[@JasonLeeFit]

I have a 320amp alt with a 14.7 bypass regulator. Problem is when the vehicle is off, there's a faint humming noise coming from the alternator. And after a day or so the battery is dead. I tapped the excited wire to the fuse box for ignition. What's the issue you think?

[@readytorvdude1224]

Hi... what alternator type is best as 2nd alternator for recharging lithium battery banks separately from engine alternator? 1 wire or 2? I need a 100A supply for 500A banks.

90 blazer 5.7 any improved or amps alternator recommendation?

[@myviews469]

I have good battery, it's 12.6v holds charge I just need to test the alternator it's the 3rd one i installed now there's 8.8v coming from the PCM wires to alternator so when I ground the other wire to see if increase in voltage at the battery but nothing. Today I will bypass the those wires his time put 12v to alternator and tap the ground again to see if battery increases to 14v.Any ideas are greatly appreciated.

[@57pontiac72]

Where can you buy the plug with the diode installed

[@1981FlyingV]

What are the specs on the diode?

[@213eddy]

What difference does the amps make cause I had a 22si and I’m thinking about getting the 40SI

[@scottschmittmusic]

Where does the white wire connect to??

[@jthetunes1]

The white wire connects to accessories on your ignition or connects to anything that turns on with the key.

[@staym925]

What diode should I use on a 24 volt altenator, I have a m35a2 deuce and half military truck with a diesel engine, im replacing altenator with a civilian altenator, but it's 24 volt 70amp, and it won't start putting out power until I touch the exciter, but I want to connect it up and not have to keep touching it, so I want put diode in and not have to use a switch to turn on and off.

[@jeremymoran2816]

Thank You sir, great video and appreciate the help and explanation. 👍

[@Nicaprince89]

Im working on an old allmond bros light unit with a Lister Peter , just installed one of these alternators and stumped why on the alternator im getting 16V and on battery its showing 12V while running. missing a good ground on alternator maybe ?

[@anthonyling73]

For 10SI Alternator, there are 4 wires plug, what are those 4 wires? In your video wire #2 is connected to the battery via a diode.

[@poormansyoutube686]

The number 2 is the L term. Connected to this light?

[@HomeBizDude]

I am going to use this for an off-auto project. Does it matter which direction the 10SI alternator spins?

[@marzsit9833]

yes and no.. the alternator will charge in either direction but the stock cooling fan won't work properly if you spin the alternator backwards so it might overheat.

[@williamskalicky2952]

Isn't 10 gauge wire undersized for a 60 amp alternator?

Hello, i have a CS 130 Style alternator with the 2 wire connector plug. But my question is, do i need a alternator with PLFS or PLIS? OR is it the same. I have a conversion from Vintage Auto Garage with the PLFS regulator for my 1954 Dodge. Hope you can help me. Best Christoph

[@vikinghauler3244]

Looks like you are using the L terminal to excite. Does it not need a resistor of some sort?

[@jmm03256]

Is there a adapter to convert?

[@charlescase1026]

Good Evening. Found your KZbin site today. I'm attempting to convert a 1948 TE20 Ferguson Tractor from 6-volt to 12-volt using a Delco Remy alternator 12 volt x 105 amp, model DREI130, remanufacture #20402. Following your video to plan the wiring harness has provided good information. The connector plug has three short wires that indicate P-L-I-S ... How are these wires connected, are all three required or only one? Appreciate any insight that you are willing to provide. TTFN/CDC

[@dodongcamirino957]

thank you for your sharing about that.

How can you a inverter with it without using battery

[@adrianjedidiah9319]

Very nice explanation i use phone hedasets to listen to you. low volume lol.but like like like this vidio

[@TheHomeProjectsYeti]

Can you use a 10g wire on a 100 amp alternator.?

[@travisabrahamson5092]

10 GA should be enough for that. You can never go wrong by stepping upto the next size. I always use 4 GA. But 10 is enough for 100 Amp alt if the factory did it. I always just go bigger 👍

[@saifbinazad3710]

Please can you make a video on how to use a car alternator for home appliances or how to wire tv, cd player or any water pump to the alternator? If the alternator shaft rotate at 1200 rmp and produce 100 amp current then will car battery over loaded. Or is there any fuse and relay circuit to control current and voltage for any appliance? Thanks in advance.

[@puredominancetattoos3484]

I knew an old Vietnam vet who could do that.

[@BillSikes.]

Home appliances use 230v or 110v in the US, an automotive alternator only produce 14-15v, in your case the amps are irrelevant

[@aaronstevenson355]

I have the bigger alternator brand new but the old style on my truck where do I get the the one wire plug or better yet how would you recommend switching to the new better alternator? My damn battery keeps dying. 1989 S10 1974 350

What size are that white wire

[@tztvue]

No wonder these Mazda's white wires are burning up to a crisp. The diodes probably popped.

[@tztvue]

Looks like the white wire is also connected to the positive battery terminal

[@magnatron7734]

White wire carries 12 volts back to alternator? Most setups it goes to the key.

What type of diode is recommended? 20ohm 10watts? Idk what to get for my 100amp alternator

[@donridzon8914]

1N5408 diode is what you want.

[@Robthewho]

Thanks man

[@ardellmoore4202]

So where does the white wire go?

[@BOSSDIGS]

Nice video

[@scottschmittmusic]

You didn't say where the 10si white wire goes

[@MechanicForGMCCars]

can you tell me sir what is pin on me 12si alternator? be me I have positive linear voltage regulator inside the dashboard I use only pin 1 with baterry bulb the pin 2 is bend inside the alternator me car dont use that pin. I have unusual problem when I use hv capacitors on me ignition system the alternator back charges up to 3000-4000rpm the alternator light come up always below that engine speed so how do I counter that problem???

[@bryantracing3022]

Where does white wire go

[@mikelangieri6602]

I switched to a PowerMaster #67293 alternator with internal regulator. So I cut the wires to the voltage regulator and capped off three, and connected the Excite wire to the brown wire. Per your setup, I'm running a heavier wire from the Alternator Post directly to the battery terminal with a Fusible Link. So I have the old alternator wire, the heavier 10 AWG factory '69 Camaro wire and I was wondering is it now going to be live, dead or live only when the key is on? Could I use that wire as a 12v Switched Ignition source? Or should I cut the eyelet off and cap that wire?

use a meter to be sure

[@gulabkeerio4392]

Good morning

[@truckstopmedia]

Hi there - If using an external regulator on an alternator that has been upgraded with an external field wire, is the connector with the sense wire and exciter wire you show here still necessary or can you disconnect it? Thank you!

[@daviderickennedy2194]

Why do the even have a sense wire? I mean why output is already right there next to it, why did they not just do that internally? Seem pointless, I don't get it. Edit: I do now. The way it's being done in this picture is pointless, incorrect. The sense wire needs to be away from the alternator, closer to the load or battery so it can see the voltage drop. Coming right out of the alternator it's going to be a false higher voltage. Doing like in the picture the alternator will maintain the battery at a lower charge, not optimally, but it will still "work".

[@joeprice3164]

How are we to be able to try the Generator when the man showing it don't speak loud enough to hear what he says.

[@randallcrane2704]

Where does the white wire go

[@Leopold1point]

So irs turned into a DC motor ? Now a speed congroller and a piwer supply is needed . can you please describe the appropriate specs of both items. And would that be useful if washing machine motor is converted similarly .

[@kathrynapo1899]

very helpful

[@ramramdeendeen6531]

Sir jab alternate ki gati badhai jati hai to aabriti bataiya

[@josephsmith2561]

I guess I missed where the other end of the white wire connects.

[@gulabk65]

Good job

[@jeffreydevoti8528]

Need to draw a simple wiring diagram for each project, labeling components. If you use indicator light, need seperate bypass circuit in the event bulb burns out. Different wiring of use voltmeter or amp gauge (wihich I don't like). Lighting circuits, starter relay, type of keyswitch used with start position or separate start button. The farm tractors I've put Chevrolet alternators on charge 14 volts at idle.

[@markvermeulen1372]

Jeffery. Any chance you may have experienced exciter wire issues? Like the alternator fails to start outputting?

The white wire on the 10, where would I run that?

[@WhoElse916]

Ignition switch

[@sultansultan5447]

One thing i can't seem to understand. The alternator charges the battery yet you plug the output wore to the + side using a conventional method. This makes no sense as in reality it is the negative the moves towards the positive. If we are to follow this then you are saying that the current moves from positive to negative. This is however incorrect. Im not sure if im missing something down the line. Can someone explain to me please?

[@blakebrockhaus347]

2 things 1. While electron theory states that current flows from negative to positive, it's common practice to wire from positive to negative. 2. The alternator casing is touching the engine, which is grounded to the battery. Which is why you don't need a negative wire

[@tynandill926]

And you guys are the only ones who make the 1 wire connector for the CS130 alternator ? Total cost is $40...yikes.

[@lindabuckler1063]
