Rated 5 out of 5 stars.
This is a brand new 63-amp alternator from AutoPowerDynamics, designed as a direct replacement for the classic Delco 10si series.
It's a 1-wire setup, which makes installation super simple for hot rods, tractors, or vintage vehicles.
It's a 12-volt unit with a V-belt pulley (class V1).
It spins clockwise.
It's an IR/EF design, meaning it's internally regulated and has an external fan.
It's built to original equipment specs and comes with a 1-year warranty.
It replaces a ton of numbers, including Delco 1100125, 10459509, and Lester number 7127-SEN.
