Got a rebuild kit on the way from summit. In the meantime I put the alt back in with a 40amp maxi fuse and turned the truck on. I also turned the headlights on, driver door open, radio on and ac on and the alt stud was reading 14.06v while those were running. With the truck running with nothing on except the door open the stud was reading just around 14.56v. The one thing that bothers me is that my volt gauge reading drops down to almost 11v with everything on (radio, lights, etc.) all of his is with a 40amp MF
I would try moving the sensing wire over to the green accessory wire connection on the junction. Are your lights dimming at idle?
