Why would Holley not include this with their kit. I spent $3000 on their harness and then I messaged them. Their excuse was well there’s a large array of alternators out there. We don’t know what people are using well most people with an LS swap are running the LS alternator absolute that kit nickels and dimes you to death.

Thankyou for a to the point video!!!! Man I was going crazy to trying to find just a normal explanation on this!!!

thank you iv looked at a lot of videos and this one told me what i needed to know

Currently doing a carb swap on my 97 k1500 and having issues not charging so this just solved my headache thanks 🤘

Doing the 5.3 turbo 91 Z71 sportside thanks for the info come in handy Hollies on backorder but it should ship out soon already have the motor the turbo and the camera built two heads and so on and so forth should be a pretty fun ride when I get done with it

Simple easy explanation. Thanks buddy!

As soon as you said “run the exciter wire to a key switch 12v source” I knew I had it wrong. Just did what you said and now it works. Thank you!! 🔥🔥

thank your being straightforward🤙🏼

What’s the part number for the top radiator hose. Perfect video that’s just what I needed to see to reassure

Right on!!! Thank you

That gives you default charging. Now run a wire from the "s" terminal on the Alt. to your junction block, and you'll get higher charging ability.(14.5-15.0v) Thanks for helping explain it to people!

this very good information my question is what does "L" stand for or mean I'm asking because I have a 2 wire alternator that came off a newer LS engine.

Thanks for the video, I have a battery drain since I install this alternator, with out an in line resistor, do you think this will fix my problem.?

86 z28 5.3 swap here as well lol sloppy stage 2 cam only and I had the pro flo system on it but wasn't working right ig my battery wasn't charging so your a life saver man lol love the build. Where you from?

Just for y'all's info: P: Pulse (or Stator Pulse). This terminal is used for tachometers, which measure engine RPM. It's like the alternator's way of saying, "Hey, look how fast I'm spinning!" L: Lamp (or Warning Lamp). This terminal connects to the warning lamp on your dashboard. When the alternator isn't doing its job, this lamp lights up to say, "Hey, something's not right!" F: Field (or Rotor). This terminal controls the alternator's field coil, which helps regulate the alternator's output voltage. It's like the alternator's way of saying, "I've got this under control!" S: Sense (or Battery Voltage Sense). This terminal is used to sense the battery voltage. It's like the alternator's way of saying, "Let me check the battery's level before I give it a boost!"

Thanks a lot!!!

U are exactly right but the wiring is different on other types of alternators . But great vid

This is also a fix for 99 to 04 gm trucks, if you have an issue with a new alternator not charging run a new wire with 470 ohm resistor from the L terminal (brown wire on connector) to and ignition source and you're done.

big help thanks. I'm in dallas what part of Texas you in?

I'm curious about the "F" wire. It seems the field wire would need to be attached also, but you say no, so I'm gonna try it your way. Thanks. Good video

Great video. Simple and to the point... which is weird for youtube. Are you planning on putting you camero on a dyno, im seriously considering running the same motor/ holley sniper setup in my nova and was wondering what kind of power you would get at the rear wheels.

When it sences your battery is charged it will turn off on it's own👍

Just use your stock wiring that came in your ls/truck wire harness and have your PCM program “Alt L” option “1” then start your engine then prove the harness alt connector “L” pin or “B” pin you should have 9 vdc as a signal or to excite the alt. If your harness has no voltage reading then you can use this video procedures. I use the stock alt wire harness with no issue.

When u said the “L” or “B” pin should have 9 vdc does that mean 9 volts for the exciter wire? Im tryin to wire up my alternator right since im pretty sure i just burnt this one up and cant figure out where the two wires from my 10si swap to on the newer cs130d

Can you just use the stock 4 plug? What does everyone do one wire? Can you just leave it as it is?

Can I just use an ignition source from my fuse box and run a wire to L using a relay? That way it turns on and off with the car?

Hey once I spliced the wire and tie in the resistor around the wire do I suppose to have power coming through the red to the connector side

Thanks

Great information, will that stay fixed at the 14 volts or will it still be regulated ?

What’s up bro LS 53 Standalone harness when I test power at the coil packs and injectors the test light goes super dim and I’m losing the voltage somewhere But a cranks but don’t start

Hey so I did this on my ls swap and as soon as there is any load like radiator fans or headlights, there's a God awful squealing that starts coming from my alternator, got any ideas?

Is the resistor the same as old school light in the dash

Where did you ground out the alternator to ?

I have the 2 wire 05 truck alternator l terminal is the signal wire but what I have read it is controlled by bcm so I don’t know what size resistor I could use to signal say 4 volts which would give me a charge of about 80% not sure it’d this would work but wow it is hard to find a whole lot of ways to make the dr44 dr36 alternator charg w

Is that a two wire or four wire voltage regulator?

Cool video... I also have a 5.3 with a standalone harness... I'm using the 411 pcm.. pinout red-18 is the alternator signal wire.. my alternator hums while the key is off.. so I used my multimeter. Red-18 is sending 7v to the alternator without key.. I bought the resistor 470ohm.. and using a switched 12v source.. multimeter shows 12v still on the other end of the resistor...

the wires came out of the plug to the alternator do you know the order of the wires i need help thanks

The brown wire right takes the resistor ?

Couldn’t you run the L wire with the 470ohm right to the main lug on the back and then only one wire to the battery. Then it wouldn’t burn it up. Or would that eventually drain your battery

I went from a cs130 to 130d; idiot light in L position.. so i need to runa wire from ignition wire to the “S” with resistor to make it charge?

Do you have a link of the resistors or part number #

What wire is for the guage on dash I have a red and brown

Wish my wires were that clean!!!! I need help getting rid of wires I don’t need!!!!

It's actually the stock upper hose that came with my 5.3 pulled from a truck. I shortened each end to make it fit and also cut about 1.5" off the water pump snout.

So all I have to do is hook up the alternator wire with 470ohm resistor to a 12 volt source what happens if you lose 12 volts when you hit the key on but than goes back to 12v when you let go of the ignition would this connection work thanks

@fatkat311

Жыл бұрын

That doesn’t matter. It will work. just follow this video. You take the single wire to any wire in your vehicle that has 12 V when the key is on. The reason the resistor is there is to drop the voltage down to a lower value which tells the alternator the battery is low and needs to start charging.

Wait I’m doing this exact thing right now and I can’t figure out how the alternator is going to send the current back to the battery. I know I’m missing something obvious, but how does that one small wire tell the holley it’s charging the battery without having a lead going back to the fixed 12V?

@KravasGarage

3 жыл бұрын

The alternator still has the bigger main power wire going direct to battery, the small wire is only telling the alternator what to do.

I ordered a 100 pack of 470ohm 1/2w resistors, and wired it just like you explained in the video. Didnt work I can take a peice of wire straighr from a battery, hook the resistor to 1 end of the wire and test voltage on the other side of the resistor and its still 12v, i ordered a 100 pack, none of them make it go down to 5v I ended up cutting the unused map sensor pigtail and used the 5v reference wire Holley should give you a 5v spaee on the harness somewhere

Side question, what is that upper radiator hose you are using?

Factory upper truck hose, I shortened the snout on the water pump about an inch, and trimmed the hose to fit. It was suppose to be for temporary use, but it worked perfect so I left it.

Yes this is exactly how you would do it. I am using a Terminator x and there really isn’t any other way to do it. Holley offers a harness you can buy for 20 or $30. I would not waste the money. You can get this connector from a junkyard for nothing.

Any tip????

Hmmmmm i put and i will check a newer alternator in my 60 gmc truck without no resistor and no problem

This may or may not be related to my issue as this is my first swap. Swap completed but my battery dies after a couple of days. Some type of draw and I can’t figure out where. I used an aftermarket harness and it had an alternator plug on it. Could this still be a possible issue and way to resolve? Any input would be appreciated
