Compatible with the stator and ignition coil of the Yamaha YFM400FA 4WD 2000 quad bike, original part number 5GH-81410-00-00--DTEKGAZ

This product is an original magnetic coil (generator coil), specifically designed for the Yamaha YFM400FA 4x4 all-terrain quad (ATV) model year 2000. It corresponds exactly to the original part number 5GH-81410-00-00 and was manufactured specifically for this model and year of the all-wheel-drive vehicle. This important component of the charging system ensures a stable and reliable power supply to the quad and guarantees the proper operation of the ignition, lights, and electric starter (if equipped) under various loads. 【Important Product Information】 Original Part Number: 5GH-81410-00-00 Compatible Model: Yamaha YFM400FA 4x4 (400cc 4x4 all-wheel-drive quad) Compatible Year: 2000 Important Note: YFM400FA models from other years may use coils with different part numbers. This product is specifically designed for the 2000 model year. Please ensure compatibility with your vehicle (year and model) before purchasing. Component Function: This product is the primary power-generating component for the magneto ignition. When the engine's crankshaft drives the external flywheel, the coil interrupts the magnetic field, generating three-phase alternating current. After rectification and regulation, this current powers the following systems: Charging System: Charges the 12V battery. Ignition System: Powers the CDI ignition module and ignition coil. Lighting and Auxiliary System: Powers headlights, taillights, instruments, and other electrical equipment (e.g., a winch). Targeted Fault Symptoms: This product helps resolve common faults due to a stator coil malfunction: The battery is persistently weak and does not hold a charge, resulting in starter failure (if equipped) or frequent recharging; headlights and other lights are unusually dim or flickering; The engine is difficult to start or runs roughly due to insufficient power. Measurements taken with a multimeter show that the charging voltage is less than 13 V or there is no output voltage (it should normally be between 13.5 V and 14.8 V).
