Is your Arctic Cat ATV having electrical issues like a dead battery, dim lights, or poor performance? The voltage regulator/rectifier might be the culprit. This part is a direct, plug-and-play replacement for the OEM part numbers 3402-682, 3530-028, and 3530-059. It's designed to fit a range of popular Arctic Cat ATV models, including the 500 from 2000-2008, the 400 from 2003-2008, and the 375 from 2002. In simple terms, this little box does a crucial job: it takes the alternating current (AC) produced by your ATV's stator and converts it to direct current (DC) to charge the battery and power your lights and accessories, while also regulating the voltage to prevent overcharging. Swapping in a new, reliable unit can get your electrical system back on track, ensuring your battery stays charged and your ride runs smoothly. The package includes one rectifier. It's a common fix that many ATV owners can handle themselves with basic tools. If you're unsure about the fit for your specific model, feel free to reach out. Ride on with confidence!
