Product Description
The RAC00079/B RR Unit is a sophisticated 3-Phase power management module. Unlike older single-phase units, this device processes three separate alternating current (AC) inputs from the stator, converting them into a highly stable direct current (DC) output. This stability is critical for BS6 models, where the Engine Control Unit (ECU) and various sensors are sensitive to even minor voltage fluctuations.
The unit features a specialized aluminum alloy heat sink with a high surface area to prevent thermal throttling. It is specifically mapped to maintain a charging voltage that keeps the battery healthy while powering the headlamp, fuel pump, and ABS module simultaneously. If your BS6 bike is experiencing battery drain, dimming lights at idle, or “Check Engine” lights related to low voltage, this genuine replacement is the factory-recommended solution.
Key Features:
-
Genuine OEM Quality: 100% original Royal Enfield spare (PN: RAC00079/B) ensuring perfect compatibility with the BS6 wiring loom.
-
3-Phase Efficiency: Provides a smoother, more consistent charging current compared to older 1-phase and 2-phase systems.
-
BS6 Calibration: Specifically engineered to meet the power demands of Fuel Injected (EFI) engines and dual-channel ABS.
-
Superior Thermal Management: Large cooling fins dissipate heat rapidly, preventing the unit from burning out during long summer rides.
-
Potted Electronics: The internal circuitry is encased in a high-grade resin to protect against moisture, dust, and heavy engine vibrations.
-
Standardized Connectors: Features the correct waterproof multi-pin couplers for a secure, “click-lock” installation without wire cutting.
