Replacement part for the GOOFIT voltage regulator/rectifier charging system for Harley-Davidson Sportster 1200 XL / 1200 C motorcycles (1991-2005).

[Specifically Designed for Harley-Davidson Sportster 1200 Models] This GOOFIT voltage regulator and rectifier was specifically designed for Harley-Davidson Sportster 1200 models. It is compatible with the following models and years: Sportster 1200 XL (1991–2003) and Sportster 1200 C (1996–2004). Manufactured to the specifications and interface standards of the original Harley-Davidson charging system, it guarantees perfect compatibility. This essential component for the Harley-Davidson V-Twin engine's charging system performs the following main functions: Rectification: It efficiently converts the alternating current (AC) generated by the magneto into direct current (DC), thus charging the battery and powering all vehicle electronics, including lighting and the high-end audio system. Voltage Regulation: Thanks to the integrated control circuit, the output voltage is precisely stabilized within a safe range (approx. 13.8 V – 14.5 V). This prevents overcharging and undercharging of the AGM or lead-acid batteries commonly used in Harley-Davidson motorcycles, protecting both the battery and electronics. 【Harley-Ready Heat Dissipation and Durability】

Efficient Heat Dissipation Design: The die-cast aluminum housing with optimized cooling fins dissipates heat during riding through airflow and contact with the frame. This ensures continuous and stable operation at low speeds and in the high ambient temperatures that Harleys can be exposed to. Vibration Resistance: The reinforced construction resists the vibrations of Harley engines, ensuring reliable connections and internal components. Quick and Easy Installation: The connector interface is perfectly matched to the vehicle's original wiring harness, simplifying installation and requiring no modifications to the wiring. 【Fixes Common Charging Problems on Harley-Davidson Models】 Replacing this part resolves the following issues:

Frequent battery discharge leading to starting difficulties, especially after connecting many electrical devices.

Abnormal battery wear, swelling, or damage.

Weak or unusual flickering of the headlights and instrument panel lights while riding (unstable voltage).

Insufficient power supply leading to distortion in the audio system or resetting of electronic devices.

【Easy Installation】 Installation is typically performed in a well-ventilated area near the frame or engine. Before installation, disconnect the negative battery terminal, disconnect the connector from the old rectifier, remove the mounting screws, replace them with the new part, and then tighten and reconnect them. Important compatibility information: Compatible models and model years: Harley-Davidson Sportster 1200 XL (1991–2003), Harley-Davidson Sportster 1200 C (1996–2005)
