"A very dim light is normal for a one wire alt." Not really with MOST 1 wire regulators made for the SI series Delco alternators built in the last 20 years. The old genuine Delco "red cap" 1 wire alternator had an extra internal wire added from the bat stud to a screw terminal on the "red cap " regulator to keep it energized all the time, and would slowly discharge the battery over time. I have not seen one of those for at least 20-30 years. Almost all the 1 wire regulators built for the Delco SI series alternators in the last 20 or so years, no longer have that connection to battery voltage, they depend only on residual magnetism in the rotor poles to excite themselves, and have no more battery drain than any conventional 3 wire Delco alternator. So today, with rare exceptions, the 3 wire Delco alternator does NOT drain the battery any faster than the 3 wire version.
