As a direct Honda OEM part, this assembly carries the exact specifications Honda engineers built into these engines, ensuring a correct drop-in replacement with no guesswork on fit or output rating. Honda supersedes parts at serial breaks, so confirm your engine's serial number against the fitment table before ordering to make sure part number 31630-ZDX-004 is the right match for your unit.
Key Features
- OEM Charging Output — rated at 17A, matching the original electrical specification Honda designed into the GX700 and GX800 to power onboard charging loads correctly
- Exact OEM Replacement — sourced directly from Honda, this charge coil assembly installs to the original mounting position without alteration or adaptation
- GX700 and GX800 Fitment — confirmed for GX700 and GX800 horizontal shaft engines; check your serial number against the fitment table to confirm applicability to your specific unit
- Restores Charging Function — a failed or worn charge coil causes undercharging or complete loss of electrical output; replacing it with this assembly brings the charging system back to its original operating capacity
The charge coil assembly is a key part of the engine's electrical charging system. Mounted to the stator and driven by the flywheel's magnetic field, it generates alternating current that the engine's regulator-rectifier converts into usable DC voltage to charge batteries or supply electrical loads. When the charge coil degrades or fails, charging output drops off or stops entirely — leading to battery drain and loss of any electrically powered accessories or control functions the equipment relies on. Replacing a faulty coil with a correct OEM unit restores full charging capacity and returns the electrical system to its original operating condition.
