The Honda 31630-ZF5-003 is a genuine OEM Charge Coil Assembly (4A) designed for EM6000 generators and GXV340 and GXV390 vertical shaft engines. As a direct Honda OEM replacement, this component is manufactured to the same specification as the original, ensuring correct output characteristics and a drop-in fit with no adaptation needed. Honda supersedes parts at serial-number breakpoints, so confirm your machine's serial number against the fitment table before ordering to ensure part number 31630-ZF5-003 is the right match for your unit.
Key Features
- Correct Charging Output — rated at 4A, this assembly delivers the precise charging current Honda specifies, protecting battery-backed systems from undercharging or overcharge damage
- Genuine Honda OEM Part — sourced directly from Honda, ensuring the windings, laminations, and connector are built to the original design standard for this application
- Broad Fitment Across Two Machine Classes — covers EM6000 generators as well as GXV340 and GXV390 vertical shaft engines; always verify your serial number against the fitment table before installing
- Restores Charging System Function — a failed or open-circuit charge coil leaves batteries unable to maintain charge; replacing this assembly brings the charging circuit back to proper operation
The charge coil is a stator winding positioned around the flywheel in the engine's magneto assembly. As the flywheel spins, its permanent magnets pass the coil windings and induce an alternating current, which is then rectified and used to charge the battery or power DC accessories on the machine. When the charge coil fails — through a shorted or open winding — the charging circuit produces little or no output, leaving the battery to discharge over time and eventually preventing the engine from starting. Replacing a worn or damaged charge coil with a correctly rated unit restores the charging circuit and protects the electrical system of the equipment it powers.
