The SM 2047 is a high-performance, ultra-high-output Alternator Rotor (Armature Assembly) specifically designed for the Denso-style (DE. Type) alternators used in the Jeep Compass (Diesel variants). Engineered to match Ref# 8320, this rotor provides a massive 12V / 150 Amps of power. It is designed for the 1-Pin intelligent charging system, which allows the vehicle's Powertrain Control Module (PCM) to precisely manage alternator output for optimal fuel efficiency and battery longevity.
