Unless their is still some weird cobbled up stuff out there, the standard "1 wire" alternator built in the last 20 years, is simply a stock SI series Delco alternator with a self exciting regular substituted for the stock 3 wire regulator. These "1 wire" units do not have anything connected to either the #1 excite terminal or the #2 sense regulator terminal, nor do they have any internal connection to the battery, as that connection is totally blocked by the rectifier assy, so they cannot run down the battery. Many years ago(30+) GM sold a 1 wire alternator setup that DID have an extra internal lead from the regulator to the alternator output stud, that one would slowly discharge the battery. You can identify those by the black plastic plug in the regulator socket, topped by the red voltage adjustment cap that can be installed 4 ways to adjust output voltage. I remember reading of another conversion, or more correctly a perversion that added a resistor between the battery stud and the regulator excite connection, to make a stock 3 wire regulator excite at lower rpm and act as a crude 1 wire alternator. I thankfully have not seen one of those for a long time and am glad, as those things are likely what gave all correctly done "1 wire" alternators the undeserved reputation of being a "battery killer."

Once started it putted along pretty good. It
