JEGS Performance Products 10100 - JEGS 1-Wire GM Alternators

JEGS 1-Wire Alternator means just that--simply connect one wire from the alternator to the battery and you're done.

For 1971-86 GM applications, replace the 63amp stock unit with a high output alternator. This line of alternators features an internal voltage regulator and turbo fan to keep internal components cool. Made in USA.

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.
