    RM stator includes the opposite connector (main harness side), as we know these are often melted / corroded/defective and a major cause of repetitive electrical issues.

    All item pictures are accurate; if in doubt, do not hesitate to compare our item to your original part.

    Benefits Of Series Voltage Regulators

    • SERIES regulators run much cooler than the Shunt and MOSFET voltage regulator rectifiers and are way cooler than OEM parts.
    • Power only flows through the electrical components when the battery is charging.
    • Allows the stator to have lower current flowing when not used, extending its lifetime.
    • The regulator is easier to mount because it is smaller than the OEM.

    About the Series Voltage Regulation Technology

    RMSTATOR’s new SERIES voltage regulator brings better reliability and charging system performance. A SERIES regulator is a significant upgrade over typical shunt-type voltage regulators.

    A shunt regulator controls battery voltage by grounding the stator coils to dissipate current as heat, rather than sending it on to the battery. SERIES regulators control battery voltage by intermittently disconnecting stator coils from the regulator electronics, limiting current flow through the unit and on to the battery completely.

    This results in lower regulator and stator temperatures, more accurate voltage regulation, and increased reliability of your charging system components.

    About the Bypass Harness

    This bypass harness allows you to connect your new series regulator directly to your battery. Bypassing feet of wire and multiple connectors on your main wiring harness to provide a safer and more direct connection.

    Materials

    Add tab content here to outline the materials used in your product, highlighting their origins, properties, and benefits. For instance, if you’re describing a jacket, detail the type of fabric used, its durability, and any eco-friendly qualities. Explain the craftsmanship involved, such as specialized weaving or treatment processes, and mention other materials like leather trims or metal fixtures to assure customers of the product's quality.

    Dimensions

    Include tab content here to detail the dimensions of your product, specifying its height, width, depth, and weight. For example, if you're describing a piece of luggage, provide measurements like the overall height with and without wheels, the internal packing space, and its empty weight. Clarify any additional dimension-related features, such as adjustable handles or expandable compartments, which offer flexibility and extra capacity.

    Care Instructions

    Incorporate tab content here to provide detailed care instructions for your product, specifying how to properly maintain and extend its lifespan. For example, if you're discussing apparel, include washing and drying guidelines, such as machine wash cold, tumble dry low, or hand wash only. Specify if any detergents or cleaning agents should be avoided and whether the item should be ironed or dry cleaned.
