I would get the alternator first, that's just me though.

Pics of the alt on the 5.3L and the one that you have would be great here

Hostility_FMX · 05-02-2009, 06:59 AM

well i was thinking after, maybe both trucks have the 105 amp? but, in the pics ive seen online, like yours, your old alt is rounded corners, mine doesnt look like your old one, but i might head over to the scrap yard and check their 145 amp out and see if its the same size as mine on my truck. ill try and get pics today.

Hostility_FMX · 05-02-2009, 10:43 AM

ok sorry i got the 145 amp alt, and put mine beside this and you can tell mine is the same as your old on, so i bolted this right up, put a 96" belt on it, works good, but i noticed my tensioner moves up and down constantly, is this normal? and i noticed the big "wheel" for the crank? is also moving back and forth.

You mean pulley?

Hostility_FMX · 05-04-2009, 05:48 AM

yea lol so is it normal for the tensioner to move up and down all the time? i took it for a good 2 hr drive test, and worked fine. didnt fix my problem totally though lol, so i need a battery asap also. but on my 145 amp alt i did have any numbers on it like yours does vortec. neither did my stocker.

B_Rich · 05-04-2009, 10:11 AM

Hm interesting.

The tensioner pulley will move some, but it shouldn't be all over the place.

How long was your belt you said? And what year 4.3L is this going on.

Hostility_FMX · 05-04-2009, 06:56 PM

its not going all over the place, just up and down all the time, the belt is 96" long, 1999 4.3L

B_Rich · 05-04-2009, 09:14 PM

That's the exact same length belt that I have on my '99 4.3L

I've noticed that mine does move a little bit.... but I've had the AD244 on there for about 8 months now with zero issues.

Hostility_FMX · 05-04-2009, 10:01 PM

yea so far it works fine, so ill just leave it! but i def have to invest in a battery hopefully within 2 weeks as my voltage likes to dance still. but in a month or 2 i will be getting the ad244 "built" thanks for all the help and fast replys vortec!

B_Rich · 05-04-2009, 10:15 PM

Yeah dude no problem.

Do take this into consideration though when you get your AD244 "built".

Your output at idle (voltage AND amperage) can, and probably will decrease. Of course, once the alternator comes to full tilt, then it will do what it says it will (depending on how hot the alternator and engine bay are). I've done some research on this and I've come to the conclusion (after talking to a couple shops and calling some shops that do this for a living) and they've told me that you will always loose output at idle (voltage and amperage) unless you get a double wound stator installed. Even then, the output at idle still won't be the same as stock. The "cheap" alternators out there only have a single wound stator, and output at idle will decrease tremendously.

It's also key to have a good rectifier installed. The rectifier converts the AC current (which the alternator originally produces) and converts that to DC current, which is what the truck uses. The AD244 and CS130D both have ~210A rectifiers, so if you go above 210A on the stator without upgrading the rectifier, then the alternator won't last very long.

If you don't wanna take my word for it, I totally understand. But talk to the guys who you're gonna have build your alternator (or unless you're gonna buy one) and ask 700 questions until you get the answers you want. I spend $200 on a 160A CS130D that had shitty output at idle, but did great at full tilt. The 12.8v and lights dimming at idle got old though.

I would just hate for you to drop $200+ on an alternator that you aren't happy with.

Good luck man.

Oh and when you do get it built up, post up your results. I'm interested to see them.

i got a 290 amp alt on the sonoma now from DC power inc. it will benched to do 165a at idle and 308 at 1400rpm.

best HO alt i ever used

That sounds like a bad ass alt, hopefully I can get my AC stuff pulled and get my cs130d on where my ac compressor currently is today, Id like to put another ad244 where the cs130d is going eventually, and I may be able to even do that today if the place I'm going to will work with trades and such, if ive got enough money left over I'll move the battery to the bed to clean up the look under the hood

Holey shieet.....

Whats your voltage at idle?

I'm assuming that's in an AD244 case, too?

yea ad244, my amp just crapped the bed so im waiting on a new one to show up. ill put up a couple voltage videos then

heres a couple pics of it

B_Rich · 05-05-2009, 02:26 PM

Ah that's right, I remember you starting that thread.

You don't need an amp hooked up to check the voltage of the rest of the truck. Is the AD244 installed?

yea, at a cold idle it will do 14.75 and warm 14.35-14.4

B_Rich · 05-05-2009, 04:19 PM

Dang, very nice

Hostility_FMX · 05-05-2009, 07:12 PM

whats the cost of a HO alt like yours stephen, rather then getting one built?

B_Rich · 05-05-2009, 07:30 PM

His is "built" you could say. I think you're referring to getting a used one and having bigger internals put in it, rather than buying a new one and getting internals put in it.

Can I take a guess at the price of it? Please don't be offended by it at all, It's just a guess.

~$300?

Stephen_C · 05-05-2009, 11:33 PM

i think its a little over 500 but they are having a 20% off sale right now.

my buddy just bought a alt from the same guy that does 150 idle 220 1400rpm for $216 shipped. mines a 290sp

Hostility_FMX · 05-06-2009, 08:38 PM

thats a lot of money, wonder if it would be cheaper to run dual stock 145amps

old_skool_noma · 05-08-2009, 02:23 PM

yes it is, but then you have to make a bracket for it and not everyone knows how to do that or has the materials or tools

Hostility_FMX · 05-08-2009, 07:09 PM

isnt there a premade one you can buy? maybe i was just reading things i was hoping to read lol. anyone know though? or have measurements to make one, my dad has cnc machines at work so he can make up anything.

B_Rich · 05-08-2009, 07:52 PM

I think they do make a kit, but don't quote me on that.

Personally, I'd just pay the $216 shipped for that 2nd alt that Stephen C mentioned. 220A and 150A at idle for only $220 is a great deal.

Hostility_FMX · 05-09-2009, 10:29 AM

hmm yea, well when the time comes ill def look into how much to go each route and figure out something, would def be easier to run 1 alt. but im just heading out to get my big battery so ill see what my voltage does with this battery. but then again im doubling my watts real soon, so who knows lol

eriley · 05-09-2009, 11:38 PM

so do we still not know if this fits on the 2.2, I just got a new Die Hard Platinum today, now it would be complete with a better alt.

^that just takes you to post #232 in this thread.

He got it working on his 2.2 cavi motor. I'm not sure if the motors are the same though, considering the fact that I don't own a 2.2

I kind of doubt that the PCM's are the same from the cavi to the s10, so I guess you'll just have to try it out and see

eriley · 05-11-2009, 12:10 AM

Yeah, definitely different. On the s10 the alt is underneath a bunch of shit, that's why I don't want to tear into it if its won't work... oh well... maybe I'll try it sometime.

I see.... well that kinda sucks

khaos288 · 05-11-2009, 11:56 PM

are there any external markings on the alt itself that would tell if its 105 or 145

I got an alt with my 5.3 package, but idk what amperage it is

not all the time, my stocker and and used ad244 both dont have any numbers on them i searched all over on them, cleaned and nothing. so i dont know why.

Are those alternators that you have both genuine AC DELCO?

BLACKBOWTIESS10 · 05-12-2009, 07:41 PM

Just put in my AD244
my stocker was getting weak or at least I just noticed how weak it really is what with summer coming, the AC going, and acc. running. I ditched the CS.

Bought it remanufacturered unit from a local wholesaler that I know. Paid 156 bucks plus 36 bucks for a Gates 96" belt. The belt number was already mentioned, #4060960 is the Goodyear Gatorback version. This belt is 1" longer than my stocker's 95" belt. I'm not sure if it was needed, but it works and the old one was exactly that.....old. I've noticed my amp gauge in my dash does not drop nearly as low when everything is on. I've also tested it with my multimeter while the truck is HOT and confirmed the guage. With system up, high beams, brake lights (brick assisted lol) AC Max high, etc I recorder a low of 13.90v to the battery. Straight off the alternators power and battery's ground- it's 14v. With everything off, it's an average 14.5. The stock CS was 12.5 and 14.4.

Let me mention a couple things. The AD244 I have does not have any numbers on it. My stock CS also had no numbers on it. They both however do have the AC Delco remanufacturered stickers labeling them. My stock CS was not the original unit from factory, that died long ago. The AD244 fits perfect. My 2001 only had two bolts holding it, so it was a direct swap. It is tight though, the wires are moved some and my heater line is now touching the alt. Might wrap it to prevent chafing or heat distribution. Dunno, here are some pics.
Next is the Big Three

belt tension

heater line

wires

two bolts, snug as a bug in a rug

B_Rich · 05-12-2009, 07:50 PM

Alternator looks great on there man. Nice work.

I don't remember having any clearance issues with the heater hose like you did...... maybe I do have issues and just never noticed, I'm not entirely sure

*goes out to truck and checks heater hose*

I hope the reman AD244 treats you better than those that I've seen in the past.

BLACKBOWTIESS10 · 05-12-2009, 07:52 PM

^^^ can u elaborate(sp?)?? There something I need to look out for lol

B_Rich · 05-12-2009, 08:19 PM

Well, I wouldn't be worried about too much, but I know 4 guys who have had problems with their reman AD244's, 2 of which had a pretty good sized system in them. I guess the regulators in them go out pretty fast.

See the "Remanufactured in China" sticker? From what I've read, they don't use the greatest quality parts to remanufacture them ("cheap" chinese parts"), so they don't last as long. I'm assuming you got a lifetime warranty with the alternator? I guess you can return a burnt alternator 4 or 5 times, and they've still made money off of them.

But dude, don't loose any sleep over this.... run the alternator just as you would normally. Whenever people have probs with their AD244 I always ask if it's a reman or from a salvage yard. 95% of the time, the salvage yard will be a true AC DELCO alternator, because it came off of a full size truck.

I don't wanna rain on your parade dude..... run the shit outta that alternator, and who knows, you might not have a problem at all.

BLACKBOWTIESS10 · 05-12-2009, 08:35 PM

damn, o well, I'll run the piss out of it, then get it either rebuilt, fixed with quality parts, or turn it into a mace.

B_Rich · 05-12-2009, 08:40 PM

**Kampz69** · 05-13-2009, 10:30 AM

my heater hose is touching the alt in the same spot, no issues as of yet.

Yeah same thing. Delphi = AC DELCO.

Weird, it should say it on the top brim of the case.

Oh well.

lol i know, i thought at least 1 of them would have a number. both have a white sticker with a number on it, but thats about it. but oh well, it works, and ill get it beefed up sometime this summer. my amp power is doubling faster then i can keep up so it will be sooner then later. and i also added my battery. and huge help from that. does about the same as yours. 14.5v warm. 14.8 14.9 cold. then after ive been bumping for a while it sits about 14.2 14.3

if they have been painted after they were refurbished (my cs130d was), the paint may have filled where the numbers were etched as the etching is very shallow and i didnt find mine till i cleaned it with a toothbrush and it wasnt even that dirty, so id say thats an entirely viable possibility

GeorgesBlazah · 06-21-2009, 10:22 AM

I got my Alt in yesterday. Guy at NAPA told me stock alt length was 96 5/8. Closest size they had that was an inch longer was 97.5, I put that on and it was waay to big. I went back and got the next styep down he had in stock and that was 97. I put it and and while its tight, It does slip from time to time if I have a couple things running. I need to double check my tensioner, but Im half tempted to see if my stock belt fits.

Oh and my Alt came from a 2000 Burban and its on my 98 Blazer.

GeorgesBlazah · 06-25-2009, 08:22 AM

FYI Since the 97in belt was slipping and my tensioner is good I put the stock belt back on. No slip, no noise and its not super tight; works great.

Then my e-fan (lt1/ls1 fans) kicked on and the voltage dropped to about 14v, still WAY better then its ever been. That was also with my stereo cranked up and the headlights on.

So I think this alternator is going to be good, I let the truck run for about a half hour and everything seemed to be operating well. I'm gonna carry my old alternator, the old belt and the tools to change it in the truck for a couple days, just in case there are any problems.

Thanks for the help getting all of this sorted.

How has this alt been treating you for the past 3 months. Have you ran into any problems?

mwhite18 · 06-30-2009, 09:31 PM

Hope this isnt a dumb question but are all the 145amps on the listed trucks the ad244 model?I dont see why GM would put two different style alternators of same amperage but you never know. The reason I ask is because I've looked on ebay and a few junkyard sites and the only option might be 105/145 amp and it doesnt necessarily say ad244 . thanks

98% sure that all of the 145A versions are true AD244 types unless otherwise stated.

"145A" should be engraved right on the case. There are a couple pics of it in this thread (I don't feel like going to photobucket and looking for the pic, sorry).

Hope that answers your question.

mwhite18 · 06-30-2009, 10:05 PM

Alright thanks for the help man. Glad i found this thread before i dropped 2 to 3 hundred on a H/O alternator.

Do take this into consideration though when you get your AD244 "built". Your output at idle (voltage AND amperage) can, and probably will decrease. Of course, once the alternator comes to full tilt, then it will do what it says it will (depending on how hot the alternator and engine bay are). I've done some research on this and I've come to the conclusion (after talking to a couple shops and calling some shops that do this for a living) and they've told me that you will always loose output at idle (voltage and amperage) unless you get a double wound stator installed. Even then, the output at idle still won't be the same as stock. The "cheap" alternators out there only have a single wound stator, and output at idle will decrease tremendously. It's also key to have a good rectifier installed. The rectifier converts the AC current (which the alternator originally produces) and converts that to DC current, which is what the truck uses. The AD244 and CS130D both have ~210A rectifiers, so if you go above 210A on the stator without upgrading the rectifier, then the alternator won't last very long. If you don't wanna take my word for it, I totally understand. But talk to the guys who you're gonna have build your alternator (or unless you're gonna buy one) and ask 700 questions until you get the answers you want. I spend $200 on a 160A CS130D that had shitty output at idle, but did great at full tilt. The 12.8v and lights dimming at idle got old though. I would just hate for you to drop $200+ on an alternator that you aren't happy with. Good luck man. Oh and when you do get it built up, post up your results. I'm interested to see them.

You don't need an amp hooked up to check the voltage of the rest of the truck. Is the AD244 installed?

I think you're referring to getting a used one and having bigger internals put in it, rather than buying a new one and getting internals put in it. Can I take a guess at the price of it? Please don't be offended by it at all, It's just a guess. ~$300?

Personally, I'd just pay the $216 shipped for that 2nd alt that Stephen C mentioned. 220A and 150A at idle for only $220 is a great deal.

He got it working on his 2.2 cavi motor. I'm not sure if the motors are the same though, considering the fact that I don't own a 2.2 I kind of doubt that the PCM's are the same from the cavi to the s10, so I guess you'll just have to try it out and see

BLACKBOWTIESS10 Tacklin Fuel Age: 28 Join Date: Apr 2005 Posts: 393 Location: Los Angeles, California User is: OffLine	Re: How To: High Output AD244 Alternator for ~$80 Just put in my AD244 my stocker was getting weak or at least I just noticed how weak it really is what with summer coming, the AC going, and acc. running. I ditched the CS. Bought it remanufacturered unit from a local wholesaler that I know. Paid 156 bucks plus 36 bucks for a Gates 96" belt. The belt number was already mentioned, #4060960 is the Goodyear Gatorback version. This belt is 1" longer than my stocker's 95" belt. I'm not sure if it was needed, but it works and the old one was exactly that.....old. I've noticed my amp gauge in my dash does not drop nearly as low when everything is on. I've also tested it with my multimeter while the truck is HOT and confirmed the guage. With system up, high beams, brake lights (brick assisted lol) AC Max high, etc I recorder a low of 13.90v to the battery. Straight off the alternators power and battery's ground- it's 14v. With everything off, it's an average 14.5. The stock CS was 12.5 and 14.4. Let me mention a couple things. The AD244 I have does not have any numbers on it. My stock CS also had no numbers on it. They both however do have the AC Delco remanufacturered stickers labeling them. My stock CS was not the original unit from factory, that died long ago. The AD244 fits perfect. My 2001 only had two bolts holding it, so it was a direct swap. It is tight though, the wires are moved some and my heater line is now touching the alt. Might wrap it to prevent chafing or heat distribution. Dunno, here are some pics. Next is the Big Three belt tension heater line wires two bolts, snug as a bug in a rug

I don't remember having any clearance issues with the heater hose like you did...... maybe I do have issues and just never noticed, I'm not entirely sure goes out to truck and checks heater hose I hope the reman AD244 treats you better than those that I've seen in the past.
