So do i just got down there and say hey i have a cummins and i bought a brand new alternator and i believe one of the diodes went bad and is causing some ac noise znd interfering with my computer causing an irradic shifting. It seems like when i used google it gives me stuff as far away as possible.

You sir are a saint!!! I didnt think to look in indiana lol i looked in southwest michigan.......duh

I dont have anything like that around me. We only have autozone,napa, O'Reillys, advanced auto. The closest alternatorshop is 150 miles

Whats my best bet for an alternator?

Ok well ill give it a shot in the morning and see if it fixes it or not. Youd think an acdelco wouldnt go bad this fast. Its not even been a week.

I havent unhooked either yet. Im just saying what do i do if it keeps doing the same thing?

What do i do if it still does itnwith it unhooked.

It would fail in a week?

Well i hate to say it but my locking and unlocking is back. I think its safe to say my apps is bad. I reset it when i swapped alternators and i thought the new alternator fixed it but it came back. What the best bang for your buck APPS sensor for a 01 24v cummins?

Yea thats exactly where i got mine. And the same voltage i got.

Yea he said yea it passed and i was like damn!! Then i said ill get thenew one anyway. And im glad i did. It was an ac delco 136amp those worth a damn? Or am i gonna be changing it again in a month? Moparman the new alternator i got fixed everything. No ecm issues and im happy lol

Autozone lol bought a new one anyway put in it no luck. Then i noticed my security blinker was on............... locked my doors unlocked them and boom good as new lol the new alternator did fix my converter issues. So i wanna tell you guys thank you very much for all your help i greatly appreciated it.

They tested the alternator and said it was good so is it my ecm?

Yea i got a 0122 1693 and a 0602 which is cause of the smarty tuner. I assume. But the apps code for low voltage is on. So im assuming the alternator died

Ok i went out to start my truck it fires up then dies almost immediately. I dont get it? Now it will crank but not fire.

Ok so thats a negative lol i want one that gonna last. But i dont want one of those grean weenie ones lol

Would this be a good replacement? http://m.oreillyauto.com/mt/www.oreillyauto.com/site/c/detail/USL1/13874N/01468.oap?year=2001&make=Dodge&model=Ram%2B2500&vi=1400061&ck=Search_01468_1400061_4983&pt=01468&ppt=C0330&un_jtt_v_thumb=4

Alright ill have the new one tested before i take it. Thanks for the help guys, this is my first cummins. Had it for a week and it started having these problems.

So i should just get a oem replacement?

Ok thank you, so i can test it withouttaking it all out. Im gonna do that first, what are the chances this is my issue? From all the posts of other people that have the same issues its the alternator. If it is the alternator whats my best bet for a new one? Should i get one woth higher amps? With my airdog 150 im nlt sure of i should get a higher output or not.

Yea i know that code usually goes hand in hand with dead pedal but so far my pedal is good. But ill pop the alternator out i guess and get her tested. I was hoping my alternator was ok cause they are a bit pricey lol

Its like the converter wont lock and its locking and unlocking. I know the alternator can do this but with the 0122 code which is the apps, Not showing up when the battery cable was unhooked it had me thinking it could be either of them. It only does it at 45mph and 55+mph it does it whether the od is on or off and with cruise control on or off.

Today i went out and popped my hood to check the oil and noticed my drivers side negative battery cable was unhooked like it came loose. I thought i fixed my apps when i reset it but i must have just forgot to put the negative cable back on the battery. So is my rapid studdering a bad APPS? or is it a bad alternator? I do have the p0122 code and it cleared while the cable was unhooked. I dont wanna replace one and have it be the other. But while the negative cable was unhooked i didnt have any issue with my shuddering. Im kinda stuck until i figure this out.cause i cant drive over 50mph without it shuddering like crazy. Any help would be greatly appreciated. Thanks, kimber
