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
- 6-Rib Serpentine Belt Pulley with Baffle & Cooling Fan

⚠️ Warning
Motor Vehicles
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
Tools
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
