The next part of this saga was that the used alternator we installed had a little issue. I heard a rattling noise over and above the usual and customary diesel noise. W. Roy Hunter and I diagnosed the issue as a bad alternator. Granted the unit we installed was used and you always take a chance, but this was certainly not expected.

What we found, aside from some angst about having to replace the alternator again, was that the shaft that holds the alternator pully had somehow become corrupted. By that I mean the pulley, even though the retaining nut was tight, would wobble on the shaft which caused more wear. Eventually, we figured that the shaft would be totally rounded and we would have an idler pulley which would not rotate the alternator at all.

So I had a spare 350SDL alternator. We removed the heat shield and the extention studs because they weren't needed and interferred with other stuff. We removed and replaced the worn regulator and I'm good to go... For now.

Oh yes, I have good voltage and all appears to be working with no warning lights showing.
