  • Our take on the Universal Fit High Output Alternator

    This is a high-output hairpin-style alternator from JS Alternators, built for vehicles with heavy electrical demand such as car audio systems, marine setups and race cars. Hairpin units are often called 6-phase and produce more output at idle than a conventional alternator while running cooler. It uses premium bearings rated for high rpm and a dual-plate rectifier with 12 heavy-duty diodes for better heat handling. It is a universal-fit part, so installation requires running a one-wire pigtail to a 12-volt ignition source and the factory wiring is bypassed.

    About the Universal Fit High Output Alternator

    This is a universal-fit, high output hairpin alternator. Hairpin units are commonly called 6 phase. They produce more output at idle and are more efficient than a conventional alternator.

    It has premium bearings to withstand high engine rpm. A dual plate rectifier with 12 heavy duty diodes improves cooling. The design is built to withstand high heat and high demand in car audio, marine and racing applications.

    It connects with a one wire pigtail harness. The harness must be run to a 12 volt switched ignition source in the fuse box. Bypassing the factory wiring will most likely cause a battery light to come on at the dash.

    Questions and answers

    What is a hairpin alternator?
    Hairpin units, often called 6-phase, use a different stator design than conventional alternators. They produce more output at idle and run more efficiently, which helps with high electrical demand.
    Why does the battery light come on after installing it?
    The one-wire pigtail bypasses the factory wiring, so the dash may not get the signal it expects. Running the pigtail to a 12-volt switched ignition source in the fuse box is required, and a battery light is likely.
    Is this a direct replacement for my stock alternator?
    No. It is a universal-fit unit, so mounting and wiring are up to the installer. Confirm the case style, pulley and amperage match your engine before buying.
    Can I return it if it does not fit?
    Universal-fit alternators are non-refundable. Check fitment carefully before ordering.
    What applications is it built for?
    JS Alternators lists car audio, marine and racing use. The hairpin design and dual-plate rectifier are aimed at high heat and sustained high output.

    At JS Alternators, for $399.00, as of our latest check.
