Will your my hero, making voltage like a champ. I'm an E7 and just today I was telling my E6 guys to trust but verify . I guess I need to listen to myself. Knowing what I know about the voltage regulators, it would have never excited the field with 24v on the 14 leg. One of the great design...

Ok so I am in the military, and should know better about assumption . When I took everything apart I had to label the main cables going to the alternator as the metal tags were missing. Easy day tagged 12 for the 12v stud and 24 for the 24 stud. Well. The last guy to hook them up in the army...

That's what I have done. I will double triple and quad check.

No luck

thats what i did, verified 24v on the regulator. im going to pull k11 and try the jump again

Well I have got a new 200amp alternator kit installed, and guess what? Yep no power. Which TM would I find the wiring diagram for this vehicle? Something is causing the alternator to not engage. I am wondering what TL6 the small wire from the 24v alt stud goes? Maybe this is my issue? I am...

If anyone is wondering the Drive End Module is N7460. and instructions http://www.ceniehoff.com/Documents/Ctrl_Hyperlink/II0094B_uid121020091146431.pdf

Well I took the alternator off, I wasn't able to get the drive end off, needs to be pressed and I don't have one yet. So further trouble shooting with the MultiMeter, i'm finding that the diode check between the Ground stud and the 28V is working, but the diode check both ways from the ground...

Well this gives me confidence to tare into it. I don't think I could thank you enough for the help you have given me. FYI the new style air dryer I got from you only needed 2 additional parts to install. The universal mounting bracket and a larger hose to npt fitting for the 1/4" control air...

I think it may be a bad diode on the 14v leg. I'm getting 30ohms where I should be getting 0. I think I should be able to test the diodes if I take apart the pulley end. Suprman you will probably be getting some parts request from me real soon. Lol.

Well I tried it all, no luck. Went through the niehoff wiring diagram and I'm not getting continuity between pins on the plug and the 14v stud on the alternator that I should be. So I may be taking it all apart and learning how an alternator works first hand. And searching the Internet for a...

I took 24v straight from the lug on the fuse panel. Metered it at 24.7v just in case I'll jump straight from the battery post. I guess worst case I could always tow my generator behind the truck. Leave the gen running powering a 24v charger and a 12v charger to keep the batteries up. Just...

Thanks for all the help. Bought a new regulator, it was delivered today, and acts same as the old one. My alternator has the fuse studs installed, that the PS magazine says to remove. I will give that a whirl tomorrow removing them, as i recharge the batteries. I find it odd that even with...

Suprman, I did exactly as you suggested, I ate my dinner as fast as i could, so i could have a few more min to work on the truck, didn't want to wait until tomorrow. no joy... got a couple more things in the niehoff troubleshoot guide. Hopefully no blue sparks, as they are with the battery hot.

I jumped E on the regulator from the 24v+ on the fuse panel, all i got was a flash of amber on the 28v light, and then red flash on the 14, repeat and then solid red on the 14v. while the engine running and also when it was off. Supraman I will try your setup tomorrow and report back. I hope...

Looking for help to diagnose why my alternator is not charging. The voltage regulator 14v light is solid red. Steps taken so far 1. Charged batteries 2. Replaced the N3207 regulator with a new one 3. Ensured all cables are tight that i could find 4. checked the K11 relay, and...
