The Honda 31630-Z4M-801 Charge Coil Assembly (18A) is a genuine OEM component designed for GX160 and GX200 horizontal shaft engines. As a direct Honda OEM part, this assembly matches the original specification, ensuring proper charging output without the guesswork that comes with non-OEM alternatives. Honda supersedes parts at serial number breaks, so confirm your engine's serial number against the fitment table before ordering. This Charge Coil Assembly (18A) is the correct replacement when the original coil has failed or output has degraded.
Key Features
- Correct Charging Output — rated at 18A to match the original coil's output specification, delivering the voltage and current the electrical system on GX160 and GX200 engines is designed to receive
- Genuine Honda OEM Part — manufactured to Honda's own design, this assembly eliminates compatibility uncertainty and replaces the original component on a like-for-like basis
- GX160 and GX200 Fitment — built specifically for Honda GX160 and GX200 horizontal shaft engines; confirm your serial number against the fitment table to ensure this is the correct variant for your unit
- Restores Electrical System Function — a worn or failed charge coil causes undercharging or complete loss of electrical output; replacing it with part number 31630-Z4M-801 brings charging performance back to specification
The charge coil is a stationary winding mounted within the engine's flywheel magneto assembly. As the flywheel rotates, its permanent magnets pass over the coil windings and induce an alternating current, which is then used to charge a battery or power auxiliary electrical loads connected to the engine. When the charge coil fails — through winding damage, insulation breakdown, or mechanical wear — the engine loses its ability to supply electrical power, and connected equipment such as electric starters or accessories will cease to function. Replacing a degraded coil restores that output and returns the engine's electrical system to normal operation.
