    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.

    10120 is rated 4.6 out of 5 by 10.
    Rated 5 out of 5 by from Nice and easy Super easy to install. Just two bolts and two wires (power and ground). I thought my old alternator was junk and as soon as I installed this one, all my battery problems went away. Oh and the black finish is really nice.

    Rated 5 out of 5 by from Awesome. Fixes everything and then some. I bought this for my tractor to run work lights, when before i was trying to figure out the original wiring and heartache and still only able to run only two lights. Now one wire and 10 lights. Awesome and thanks

    Rated 5 out of 5 by from Problem solved I was constantly changing batteries if the truck sat for a few weeks. I've even replaced them. This alternator solved the problem. Even if I don't drive the truck for a few weeks, a few pats on the gas and the 454 in Agness fires right up.

    Rated 4 out of 5 by from Looks good & works great I recently installed a 10120 JEGS 1-Wire GM Alternator on the SBC that I swapped into my '55 2 ton Chevy truck. The alternator looks at home on the motor and works well to charge the battery, power the electric fan, and lights. Great product for the price.
