Electrical is my weak point. I do have an understanding of the particular functions of most things electrical on these trucks through experience, though. I just don't have a full understanding to be the one giving advise. I am an advise taker in this area.

I have never experienced an overcharging system, yet I feel your issue is similar or the same as one I had in my old blue & white K20. I kept smelling rotten eggs and I never hauled eggs in it. Never saw a bird nest under the hood (at least not near anything real hot). It seemed to be coming from under the hood. I noticed the battery was warm enough to cook an egg, but no eggs in sight. It was a new optima marine battery. IIRC, I got to my old shop and the starter wouldn't crank. The purple(?) wire didn't look good so I went with new from the fuse block. Fixed that problem but still the rotten egg smell. I went with an later internal regulator alternator and the smell ended. I never considered that a one wire set-up. It used the two wire plug on the alternator and harness and eliminated the white(?) wire to the voltage regulator. Everything was still there if I every wanted to go back to original. It was really easy and straight forward. I hate the smell of rotten eggs. I'm glad I didn't get any on me or my truck. That could hurt.
