A 105-amp, 12-volt one-wire alternator built for GM 305, 350 small-block and big-block engines, in the 10SI style with a chrome finish. The self-exciting one-wire hookup means a single charge wire to the battery, which suits street rods and custom builds with simplified wiring. It uses an internal regulator, clockwise rotation and an external cooling fan. Against a stock 10SI alternator it roughly doubles charging output, but it is a generic-brand part with a 30-day limited warranty, so expect less support than a name-brand unit.
