JEGS 1-Wire GM Alternators

These 100 amp, high output, 1 wire alternators are available in either chrome or black powder coat. They include either a V-Groove Billet or 6-Groove Billet serpentine pulley. They have a unique casting design with a smooth case for a clean look. The Turbo Baffle Fan provides increased cooling. They also feature a self energizing, built in regulator, jumbo button diodes and heavy duty copper windings. Fits all Ford V8's except modular engines (4.6L, 5.0L and 5.4L) and FE (352, 360, 390, 427 & 428). 

Unique Charging Feature 

A one wire alternator has a turn on point (sometimes called "cut in", which is typically about 1200 engine RPM). We have developed rotor poles and stator stacks that carry a higher magnetism thus providing an instant regulator cut in without engine acceleration. All of our 1-wire alternators are manufactured with this exclusive low cut in feature at 880 engine RPM which is much lower than any other alternator (of its type) sold. This is the speed where the internal sense circuitry connects the battery to the voltage regulator, thereby turning the alternator on. Once the voltage regulator turns on, the alternator will remain on and charging until the engine comes to a complete stop.
