This starter solenoid relay is a high-quality aftermarket replacement designed for Polaris ATP 330 and ATP 500 4X4 ATV models from 2004 to 2005. It acts as the main power switch of the starting system, delivering stable 12V power from the battery to the starter motor for smooth engine cranking.

Made with heavy-duty fully sealed housing and superior internal components, it effectively resists moisture, dust, corrosion and strong off-road vibration. It solves common starting issues such as intermittent cranking, clicking noise and no-start failure, which is an ideal cost-effective spare part for daily ATV maintenance and repair.
