Awesome video! I'm about to try and rebuild the alternator on my 2002 Chevy Venture, and I think you might have just given me the edge I needed. The van's at 325,000 miles right now and I'm trying to hit at least 500,000 before I'm willing to get a new vehicle
It depends on the engine in your Firebird. If you have the 5.7L, that Bosch unit and the AD244 series alternators will fit. If you have the 3.8L, only another CS130D will work.
The problems with the CS130D is why I retrofitted my 97 Lumina to a CS144 from a Tahoe. It only required swapping the regulator plug and adding the remote sense wire.
The Ford Focus alternator is not technically controlled by the PCM, it has an internal regulator that communicates to the PCM. The only way to full field it is by opening the alternator up and finding the ground-to-test connection.
just a quick question for you while changing the alternator on my old Mercedes diesel I discovered that somebody had changed it to the cs130 just like the one you showed in this video. this was an upgrade to the original 50 amp alternator that was on the vehicle. what is the part number for that specific alternator that you showed in the video or what vehicles did it come on because when I Google the cs130 the mountains look quite different than the one I have which is the one like you listed thank you in advance
Great videos, im learning more and more just by watching them. I do have a question, however. So if im in the market for alternators, what do i need to keep in mind to prevent from purchasing the wrong one for my vehicle?
@moparerrnocar 5 months ago, whew ! Anyway, if you go to the Dixie Electric website, they have an electronic e-catalog with all the pics. WAI Global also gives details about all the vehicles you mention. Funny how newer Ford alternators have a brush holder similar to the CS130d units.
Yes, you can interchange the 244 with the 130D, but you have to change the belt because the geometry is different. Changing the alternator pulley won't help.
I have a 2003 infiniti G35 coupe with a overcharging @15 amps alternator. I changed the alternator out and it is still overcharging. Batt indicator light is still on in the dash. Any ideas what's going on?
Odds are the the bridge rectifier has failed. Stock rectifiers are not designed to handle 300A output, but many rebuilders and high output alternator manufacturers will use a 300A stator with a 200A rectifier.
when field testing, is it neccessary to plug in the 4 pin adapter to the voltage regulator, or do you leave it unplugged and test as described, I left mine unplugged and read 18Volts when I bypassed the voltage regulator, is this the correct way to test,or do I need to re-test?
I know this is from awhile ago, but I have a stereo and stuff in my 2007 GMC Sierra and it’s takin a toll on my alternator. I can rebuild this myself right?
Hi, I have a 2007 chevy uplander and the lights pulse at idle. I heard it's the regulator. Do you have a video for that type? I tried it once but I couldn't get the new brushes on correctly.
I'm curious what "sound" you get with a good rectifier bridge when you touch that lead. I'm in the middle of testing my alternator. Looks like a bad rectifier bridge. Definitely not brush's. I'm just curious if it's a specific sound a bad alternator makes, or just the fact the stator grabs the windings in the first place?
Ive got a 99 chevy silverado. When I start it for the first time on a cold day or morning i get a battery light and it seems like its not charging.. After about 30 minutes of idling, it will suddenly start charging correctly and will remain working correctly all through the day. The next day though it will do it all over again. I seems like the cold is what is causing it and once it gets a bit warm under the hood it starts to charge again.. I hope you can help. :)
hopefully you can help me I think it's my alternator and not my battery. I have a 2007 GMC Yukon XL. Yesterday my battery symbol came on. After driving 10minutes my dash instrument panel went out completely including my speed odometer. I was able to drive until I had to stop for a red light then it died. Im sure it's the alternator because the battery is only 2 months old. is there a way there a why to test the alternator without taking it off. it's the original alternator with 220k miles thanks hopefully you can help
Also if you soak your alternator in power steering fluid it stops working. But if you soak that alternator again in break clean it will start working again.
i have a 300 apm alt the is not giving out the full amount of power any more, when i remove the terminals i stay start but when i gas it it does not increase power. what could be the problem?
Before going through the hassle of putting a used alternator in my Chevy Venture (3+ hr job), I figured I'd test it first. 120 amp stock gm 10317648. Ain't forking out $370 - $410 for one. Considering you can buy a Venture for that price. Meter is reading 11.6v DC/30v AC on running vehicle. Battery has intermittent drainage which has been going on for about a year. All because of AC voltage flowing past rectifier diodes. I have the same poor design as the unit on the left.
@@mattfoxlikesretro Yep! And guess what? I just replaced the damn alternator AGAIN about 8 months ago. That's my fault because I put in a junkyard one. They are much more affordable today than they were 3 years ago. I think I paid like $80 + core charge on RockAuto.com.
I've also gone through and fixed multiple wiring faults underneath the carpet and floor. If you're having interior electrical problems, fuel pump/fuel gauge issues, or cooling fans not kicking on, I can tell you how to fix all that. I made multiple videos on it but never uploaded them.
@@markfothebeast Yup, and yup! I've also got an intermittent problem with the running light fuse blowing, sometimes it takes a week to blow, sometimes it blows 6 times in a day! I haven't had the time or money to really do any digging yet, but it's in the works. It's at 325,000 miles right now, trying to see if I can get it to 500,000 before a wiring problem burns it to the ground lol
@@mattfoxlikesretro Pull off the plastic door jamb covers on both the driver and passengers side. Dig in to the wiring harnesses on both sides under the carpet by the front seats. Get ready to pull out a soldering iron. There's multiple junctions where 3 wires are soldered together. They are probably all corroded. I'm not 100% sure on the lights but I do know that others had issues with rear tail lights. This and running light wiring may be on the plugin that goes to the fuel pump and fuel sender. It's literally 10" behind the drivers seat under the carpet. The other end is accessible and can be unplugged from under the van. I cut slits in the carpet to get to this. My van literally died in the middle of the road and once I wiggled the plugin it started back up. I eliminated the entire plugin by marking and soldering the wires directly together. It was corroded to hell inside.
yeah i got a 03-04 ad244 on my 98 trans am (ls1) way better, i don't have my lights pulsing but i want bigger. i live in a cold area and i installed a 850 cca battery. and i plan to add a 1500 watt mono block. on top of a 400 watt amp (rms) so any ideals?
Im trying to replace the voltage regulator on an AD alternator. The regulator has a large contact in the form of a ring that goes under the metal space and the main voltage output. I cannot move the large metal cylinder - how does one remove it. Its absolutely solid and wont turn using grips after soaking in penetrating oil.
my alternator for my 2002 chevy venture is “discontinued” is it just the housing that is different? i was going to put a slip ring on my old alt, but would rather buy new. can i buy a new alternator and put it in my old housing?
@utubin67 Sure it's easier to buy a brand new car every time you have trouble but not everyone can afford a new car all the time. Some people need to save the money or they don't trust mechanics or rebuilt alternators. This gives people more knowledge to understand what is going on. You said it all when you said your vehicle is a $ vacuum. When you fix your own vehicle your making per hour what your mechanic charges. My neighbor has a garage & charges $65.00 per hour, I know some charge more.
I certainly appreciate what you've done here. I had an '03 Tahoe that I replaced an alternator on($60 from the salvage yard). I now have an '04 Suburban and am now rebuilding/conditioning the original from the '03 Tahoe. Seems I'm having some trouble with the '04 alternator. Thanks for the help.
Hi Mr Alternator Man, I intend to use a windmill hocked up to an alternator to produce electricity and i have a couple of questions. 1- what ill be the wiring i guess i need to have a bridge to have the alternato on all the time. 2- what are the minimal RPM needed to produce electricity. 3- without regulator what will be the electricity output ? thanks in advance for your time Regards
maybe you can help i got a ford focus 2006 and the alternator well took it out and had it checked at aouto zone not a fan had trouble with these guys well any way was not good so i bought a new put it in worked for about a week and doing the same thing again bat light came on do u think the alternator went out or going out remember this id aouto zone stuff i was reading on line that autozone parts u might have to change them out untill u get a good one
I checked the diodes...multimeter test with positive on casing and negative on battery post, and it passed(.536) reading. So I did your bench test connected to battery and running off an electric motor. I touched the positive jumper to the brush positive and it made that ugly sound! How does it test ok for diodes and bad on the bridge rectifier when all a rectifier is is diodes connected together in a circuit? If the diodes are good, shouldn't the rectifier be good? Curious. Thx
Hi Alternatorman. I have a 2002 duramax that recently had an voltage regulator fail in the alternator. I was in a pinch and needed my truck so I bought a replacement from orieleys.

Hello How come my question wasn't answered about the newer types of GM alternators from the year 2000 to 2007. I would appreciate your reply to this from me.
How cant I tell whats causing a intermittent charging problem on a 06 chevy express 6.0? Will the bridge rectifier cause this. You state that the voltage reg turns it on and off. The pcm also does the same thing. Any help would be greatly appreciated
I would be a bit reluctant to test the coil by 'sparking' the terminals as shown in this video. Especially so since there's also electronic control circuitry (regulator) connected to the brush terminal. I don't think semiconductor components like being 'sparked'.
I've got a 2008 GMC Sierra SLT DR44 160A alternator, I have a system, off road lights and etc, I ordered a 300A alternator and now volt gauge changes from 14.8 to 13.5v GM forums say it's a hiccup in our year trucks?? Should I put my stock regulator back on? And the company put a billet pulley on for better idle. Doesn't matter if I drive or parked, if I turn key off then on, voltage goes up. Battery still good it's a 12v/16v kinetic blue battery. Please help!!! Alt man I'll buy a heavy duty regulator from you if need be
Howto is targeted at someone with limited or no tools. A continuity test, either with a test light or multimeter, would be ideal, but the "spark test" is common in the field.
hello sir, I have a Opel Vectra C with an 120A alternator(code 0124425009) and the charging is low max 13.3V and when I turn the steering it will drop to 12.7. The battery was change 1 mouth ago and still nothing, I have replace the regulator and the diodes and the charging is the same the slip rings are good they have only 0.5mm wear. can you help me
+David Smith Wholesale parts houses that won't sell to you in the first place. But eBay fills the need nicely. I asked the NAPA guy why in the world they didn't carry a single brush holder for a Delco 10-SI once considering that there were probably a million of them spinning at that very moment. Nothing but evasive lies followed as he really doesn't want to sell me alternator parts, he wants to sell the entire unit. I'm the fool for asking him too - duh.
Funny thing is most alternators are made by bosch or denso. So congrats on using a german designed or Japanese (denso) alternator on your american car :P Right on the money animalcorvair weak or dead batteries kill alternators. The alternator is meant to run the car accessories and keep the battery charged, not charge a battery from a deep cycle or constantly keep getting strained trying to force a battery to hold a charge. Chargers are meant to charge deeply discharged batteries :)
***** All GM alts (in US at least) are Delco, Valeo, or Bosch so American, French, or German. Delco 10SI & 12SI alternators, now 20 years obsolete, are still sought after in junkyards for their reliability and simplicity.
Using yellow wires for both positive and negative, fantastic idea.
Lmfao 🤣🤣

thank you for take the time on making the video..
good testing work thanks sir ..
Great work
We actually build the AD244 series alternator up to 200A with an upgraded internal bridge rectifier, or up to 250A with an external rectifier.
It depends on the engine in your Firebird. If you have the 5.7L, that Bosch unit and the AD244 series alternators will fit. If you have the 3.8L, only another CS130D will work.
Thank you so much! you're awsome
Good job
The problems with the CS130D is why I retrofitted my 97 Lumina to a CS144 from a Tahoe. It only required swapping the regulator plug and adding the remote sense wire.
Check all of the connections to the alternator, as well as your plug.

v nice job
I have a DR44G off an 04 Tahoe I'm installing it on a 92 Chevy truck it has the four pin what wires do I need to hook up to make the output 14.5 volts
Yes, you can interchange the 244 with the 130D, but you have to change the belt because the geometry is different. Changing the alternator pulley won't help.
Check out the website in the video description, we ship worldwide.
I have a 2003 infiniti G35 coupe with a overcharging @15 amps alternator. I changed the alternator out and it is still overcharging. Batt indicator light is still on in the dash. Any ideas what's going on?
Depends on the year. Model years 1997 and earlier with the 5.7L engine can take a 350A CS144, 1998 and after use the AD244.
Are these in the saturn ion ecotec 2.2? all the lights in my car flicker and even the engine surges. Is that the alternator or pcm?
Odds are the the bridge rectifier has failed. Stock rectifiers are not designed to handle 300A output, but many rebuilders and high output alternator manufacturers will use a 300A stator with a 200A rectifier.

Test for AC voltage. A failing diode in the rectifier will allow AC to pass causing intermittent battery failure/drainage.

+David Smith Wholesale parts houses that won't sell to you in the first place. But eBay fills the need nicely. I asked the NAPA guy why in the world they didn't carry a single brush holder for a Delco 10-SI once considering that there were probably a million of them spinning at that very moment. Nothing but evasive lies followed as he really doesn't want to sell me alternator parts, he wants to sell the entire unit. I'm the fool for asking him too - duh.
no one does that here. i get only 180 amp. no point in upgrading for 30 amps
Sir ji alternator ke sare itom checking karke hindi me dijiye
verga, como tardas hablas demasiado.
lol should tell him some cars there is no such thing as new. mainly re manufactured.
GM alts shit . give me anything from japan
no way gm made the best what kills them bad batterys
go to japan then
Funny thing is most alternators are made by bosch or denso. So congrats on using a german designed or Japanese (denso) alternator on your american car :P
Right on the money animalcorvair weak or dead batteries kill alternators. The alternator is meant to run the car accessories and keep the battery charged, not charge a battery from a deep cycle or constantly keep getting strained trying to force a battery to hold a charge. Chargers are meant to charge deeply discharged batteries :)
***** All GM alts (in US at least) are Delco, Valeo, or Bosch so American, French, or German.
Delco 10SI & 12SI alternators, now 20 years obsolete, are still sought after in junkyards for their reliability and simplicity.
TH-cam history erase
You didn't repair a damned thing!! Just list this video as testing SOME of your alternator.
