John T, just one bit of misinformation I would like to clear up about Delco "1 wire" alternators. While the Factory built Delco "1 wire " alternators like the 27SI did have a direct connection from the battery to an extra stud on the regulator which may have put a constant small load on the battery, the aftermarket conversion "1 wire" alternators do not have this extra direct battery connection to the regulator,and can not drain the battery any more than a stock "3 wire" Delco 10SI. The aftermarket "1 wire regulator is totally isolated from battery voltage by the rectifier diode pack. In every case I have found of an aftermarket "1 wire" Delco conversion,or a stock"3wire"Delco10SI draining the battery,The problem has been a leaky or shorted button diode in the rectifier pack,or a leaky or shorted electrical"noise" supperssion condenser. Many people see a tiny blue spark when connecting the battery wire to the alternator stud,and assume the alternator has a short. This tiny blue spark is just a momentary drain of the noise suppression condenser charging itself from the battery. Once charged,the power drain is gone Many times the "short" can be eliminated by a simple disassembly and cleaning to remove a layer of conductive brush dust from the internal parts which is causing the electrical leakage.
