The Honda 31630-ZF5-801 Charge Coil Assembly (1A) is a genuine OEM component designed for GX390 horizontal shaft engines and GXV340 and GXV390 vertical shaft engines. As a direct Honda OEM part, this Charge Coil Assembly is manufactured to the same specifications as the original, ensuring it integrates correctly with the existing ignition and charging system. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and more than one variant may be listed for these engine families.
Key Features
- Genuine Honda OEM Construction — sourced directly from Honda, this Charge Coil Assembly delivers the same output characteristics as the original unit, maintaining correct charging voltage for the engine's electrical system
- Charging Output Integrity — a properly functioning charge coil keeps battery-backed accessories and ignition components supplied with consistent current; a failed coil results in a dead battery, erratic ignition, or a no-start condition
- Direct OEM Replacement — engineered to drop into the flywheel magneto assembly of compatible engines without modification, using the original mounting points and wiring connections
- Broad Engine Compatibility — fits GX390 horizontal shaft engines along with GXV340 and GXV390 vertical shaft engines; confirm your serial number against the fitment table, as Honda issues part supersessions at specific serial breaks
The Charge Coil Assembly is a generating coil mounted in the engine's magneto, positioned around the flywheel. As the flywheel spins past the coil's magnetic field, the coil generates AC current that the engine's charging circuit uses to power electrical accessories and maintain battery charge. When the charge coil fails or degrades, the engine may still run but will no longer supply current to connected electrical loads — leading to a progressively draining battery, loss of electric-start capability, or failure of any accessory powered by the charging circuit.
