    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 1971-86 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.

    10100 - JEGS 1-Wire GM Alternators is rated 4.9 out of 5 by 16.
    Rated 5 out of 5 by from simple conversion I bought this Alternator to up the charging amperage of my 69 Camaro. and converted it to the 100 amp internal regulator alternator. The install was very easy. It fit in the mounts of my 62 amp piece and by using a alternator conversion kit I changed the wiring over in five minutes which included removing the external voltage regulator. This was a simple swap that made a big improvement in the Camaro

    Rated 5 out of 5 by from Easy hook up, great price. I was looking around and bought this chrome alternator cheaper than I could buy a stock one locally, showed up on time and I didn't have to spend any money or time running around to get one. Thanks Jegs

    Rated 4 out of 5 by from Exactly as advertised I've had it installed for about a month, and it's working exactly as intended. Installation was simple, and the wiring recommendations were very useful.
