How to: GM12SI alternator on a small block
I used to run a Delco back in the mid '70's when I had the 340 in the old '70 Sixpack RR body. Don't worry about application and clock position, YOU CAN CHANGE THAT
I don't recall, anymore, it seems to me I hack-sawed "something" off the rear of the alternator to clear the head. (It's only been 40 years!!!)
Also, you really don't need that resistor BUT YOU DO NEED the diode. This is to prevent the diode trio from becoming the charging source under certain conditions.
We used to sell a lot of these for tractors, etc, and I used to make a little pigtail. Just jumper terminial no2 to the battery stud, and put the diode in series with the no1 terminal.
Also, I don't have the number handy, but the "right" regulator will turn any of these into a "one wire" if that suits ya.
