1-Wire GM Alternator 140 AMP Output 12 Volt GM 10Si Internal Regulator 5/16 in. -18 .3125 in. Stud Terminal Size Natural Finish Includes: 3/8 in. W x 2.33 in. O.D. Single Groove V-Belt Pulley Fan JEGS 1-Wire Alternators: 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 1-wire 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. Once the voltage regulator engages the alternator will stay on and charge until the engine stops completely. Features: 1-Wire Hook Up Low RPM Charge Output Internal Regulator Single Groove V-Belt Pulley with Cooling Fan
- SIMPLE INSTALLATION: Connect one wire from the alternator to the battery and you’re done
