GM 1 Wire Alternators - Chevy One Wire Alternator

Time for Alternator Repair or an Upgrade?

JEGS 1-Wire Alternator means just that... simply connect one wire from the alternator to the battery, and you're done. One-wire alternators have a turn-on point (sometimes called "cut in"), typically about 1200 engine RPM. JEGS has developed rotor poles and stator stacks that carry a higher magnetism to provide an instant regulator "cut in" without engine acceleration. Our alternators are manufactured with an exclusive low "cut in" of 880 engine RPM, which is much lower than any other alternator of its type. This is the speed where the internal sense circuitry connects the battery to the voltage regulator and turns on the alternator to start charging.
