Hey guys, so after my last post, decided to get my transmission rebuilt and decided that I am going to take the best care of it in general now. My alternator is squealing (already replaced idler, tuner, and belt. Can hear it if I turn the alternator by itself). My question is: what alternator do I replace it with? I checked out o reilys and they were asking me clock position, what amp, etc... I have absolutely no idea. It has power locks, windows, A/C, the good stuff. Manual seats. Anyone know what I'm supposed to use? Any help would be greatly appreciated. I get my blazer back this Friday and plan to do some work to it over the weekend.

 

just take the old one off and take it up there they should know that stuff or be able to look it up

 

Stock alt is CS130D I believe. Putting in a AD244 with a 1" longer belt is a better idea. That squealing is the alternator bearings.

 

If you plan on offroad lights or big stereo etc, an ad244 from the junk is what you want. Stock alt is 100 amps i think, an ad244 is 145

 

Not to hijack too much, but other than the belt, will the ad244 bolt right up, without modifying anything else?

Once I can figure out where to put it, I want to put in a second battery, and a little more juice from the alternator would be nice.

 

yes it will

 

Yea I know the squealing is the bearings of it. No, I don't plan on doing anything special to it other than using it as a daily driver and moving my belongings from apartment to apartment when I move. Ok, I'll just take my old one off and take it in. Another question, I noticed that they all looked different. Like mine had an extra housing that they didn't. Does that matter? Or can I just take the housing off my old one and put it on the new one?

 

Just making sure. Sounds like you were replacing things to get rid of that noise.

Got pics of your alternator? You talking about the black cover at the back?

 

Thanks for the video, haven't watched all of it but probably the first half. Really informative. I don't have any pictures of it right now, I'll get it back from the tranny shop on tuesday next week so I'll get some pictures of it sometime next week. What I was talking about is like an extra bracket that is on top of the alternator that new ones don't have.

 

You can also get a DR44G alternator, which is just a different version of an AD244 and it will still bolt right up. Make sure you get one with a 4 pin connector and not a 2. The voltage regulator can be swapped out but they aren't cheap and it is kind of a pain.
