S Series 240A Racing Alt - Replaces L Mount CS130 - Machined

The S series of 6 phase alternators offers incredible low RPM output in a compact and durable package. Highly efficient, these units use less horsepower than conventional 3 phase alternators. 12 diodes, twin rectifier plates and outstanding airflow ensure much better durability than standard Delco CS130 based alternators, even in severe conditions. This custom designed housing directly replaces standard CS130 "left mount" alternators as used on 1987-1995 Chevy C1500 Pickups and some aftermarket accessory drives. A single wire on the provided pigtail gets connected to any ignition switched 12V+ source to turn the alternator on and off with the ignition switch. Simply run a properly sized positive and ground cable from the alternator to the terminals of the battery and the alternator will work perfectly, regardless of what kind of wiring harness you have. Because of their compact size and standard GM mounting ears, these alternators also work well in many aftermarket or custom bracket installations.
