Product Description
1025100FD020 Alternator is the engine-driven charging generator matched for JAC HFC4DB2-1D diesel engine. Driven by the PK belt from crankshaft pulley, it converts mechanical rotation into electric power to charge the storage battery and continuously supply electricity for cab lights, ECU and all onboard electrical loads during operation. This aftermarket replacement alternator resolves low charging voltage, intermittent charging failure, abnormal whining noise and battery drain caused by worn carbon brushes, rectifier diode burnout and stator coil aging of old units. Stable charging performance avoids dead battery shutdown risk for JAC light trucks used for urban delivery and frequent stop-and-go logistics routes.
Product Advantages 12V high-efficiency winding structure provides stable output under different engine speeds. Built-in precision voltage regulator prevents overcharging that damages the battery. Sealed housing structure blocks road dust and splash water to protect internal coils and rectifier module. Each alternator undergoes full-load charging test, ripple and insulation inspection before shipment, OEM mounting foot and plug connector for direct plug-and-bolt installation.
