The Wilson 90-01-3135N is a new 12-volt, 61-amp alternator built on the Delco 10SI family pattern. It uses an internal regulator with external fan, negative ground and spool mounting, and its aluminum case keeps weight near 11 lb. It suits older trucks and cars that need a simple one-wire-style replacement for a tired 10SI unit. Compared with higher-output alternators, 61 amps is modest, so it fits stock electrical loads rather than winches or big audio systems.
