RMSTATOR Red Machined Aluminium MOSFET Regulator

The red CNC-machined aluminium MOSFET voltage regulator is designed to improve heat dissipation in powersports charging systems. After 10 minutes of use, its billet aluminium heatsink runs up to 33% cooler than standard cast regulator housings. Equipped with MOSFET regulation technology, it is suitable for three-phase permanent-magnet charging systems.

• Runs cooler than OEM diode-style regulators.
• Overheat protection temporarily switches the regulator off to cool down instead of burning out.
• Direct replacement for the original unit.
• Plug-and-play, direct fit and easy installation.
• Quality exceeds OEM equipment.
• Improved heatsink and charging capabilities.
• Higher-grade electrical components.
• All products are tested before shipping.

The opposite connector (main harness side) is included. Original connectors can become melted, corroded or defective, causing recurring electrical issues.

Why use MOSFET technology?

• Runs cooler: Operates at lower temperatures than traditional shunt voltage regulator/rectifiers.
• Saves fuel: Reduces the load on the stator, requiring less engine work and fuel.
• Smoother charging: Provides steadier, smoother power to the battery.
• Extended battery life: Helps extend battery life and cold-cranking capacity.
• More engine power: Reduces stator load, allowing more engine power.
• Optimised performance: Advanced design lowers operating temperatures for improved longevity and performance. Power delivery is optimised by switching stator coils on or off.

Before installing the new stator:

• Check the AC output of the stator.
• Replace any burned or corroded connectors on the stator and regulator/rectifier.
• Check and repair any melted wiring.
• Apply high-temperature dielectric grease to all connectors.

The stator may have a different wire colour code from the original part. All wires are installed in the correct order; do not change the wiring configuration. This stator is designed as a direct plug-in replacement.

Always use thread-locking compound when securing the stator. If the stator includes a pickup coil, check the air gap during installation. Set it as close as possible, but no less than 0.010".

Before installing the new MOSFET voltage regulator/rectifier:

• Check the AC output of the stator.
• Replace any burned or corroded connectors on the stator and regulator/rectifier.
• Check and repair any melted wiring.
• Apply high-temperature dielectric grease to all connectors.

Warning:

Risk of electric shock. Disconnect the battery before servicing. Ensure proper installation by a qualified technician to avoid malfunction.
