From what Dennis said and what I have read, I'm sure that the Dennis has the Denso alternator, not the Delco SI.
What I meant when I said I'm speaking about a Delco 10SI is that I believe the two shown in Dennis' link are wired the same as a 10SI. Not that one of them was a 10SI.
The rear of the ACDELCO 3342021 is configured like type 2 of Gord's link (Westfield World.com). It has 4 connections. Has the circular receptacle with three blade terminals and a separate battery stud. I hope that this "smaller" alternator is really necessary.
At any rate Gord has provided electrical hook up for a Denso. May be the same as your Delco. The last link spends a lot of time saving 1/2 volt and discourages the "jumper thing", but is very informative.
The dead horse has been beaten.
