    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.

    For 1971-1986 GM applications, replace the stock 63-amp alternator with a JEGS high-output unit that has a voltage regulator and turbo fan to keep internal components cool.

    Unique Charging Feature

    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.

     

    JEGS EZ Kits are designed by JEGS professionals to ensure that you get all the correct parts you need.

    Rated 4 out of 5 by from awesome looking alternator looks good and hopefully functions as it should. I rated as 4 star since I have only installed and cannot comment on the function yet. Installation was a breeze only recommendation is getting a new bolt for the spacer. I plan on running a 6g or a 4g ground wire instead of the recommended 10g wire. Also the fan is starting to show a small bit of surface rust but not a deal breaker.
