This product is a direct replacement stator coil (magneto coil/alternator coil) for Yamaha YZF-R3 motorcycles (and the MT-03 of the same platform). It is an exact replacement for the original part number 1WD-H1410-00 and was specifically designed and manufactured for the 2015-2018 models. This coil is the central component of the motorcycle's charging system; it ensures a stable power supply and effectively resolves power outages caused by a coil failure. 【Product Details】 Original Part Number: 1WD-H1410-00 Compatible Models: Yamaha YZF-R3 (2015, 2016, 2017, 2018) Compatibility: Generally also compatible with the Yamaha MT-03 (2016-2018) of the same engine platform (please check before installation). Function: The stator coil is a fixed component within the magneto ignition system. When the motor drives the external magnet rotor, the coil interrupts the magnetic field lines, generating three-phase current that powers the entire vehicle electrical system and charges the battery. Corresponding symptoms: This product resolves the following typical problems caused by a damaged stator coil (burned out, short-circuited, or open circuit): The battery does not charge and remains weak after driving. Headlights, taillights, and instrument lighting are unusually dim or flickering. The vehicle is difficult or impossible to start. A multimeter reading indicates a low or no charging voltage.
