JEGS 10163 1-Wire GM Alternator 140 Amp Output V-Belt Pulley Chrome Plated Finish

W x 2.330 in. O.D. Single Groove V-Belt Pulley Fan JEGS 10163 1-Wire Alternator: 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 inwithout engine acceleration. Our 1-wire alternators are manufactured with an exclusive low “cut inof 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. Once the voltage regulator engages the alternator will stay on and charge until the engine stops completely.
