The Honda 31715-Z2E-013 Rectifier is a genuine OEM component designed for GX440 horizontal shaft engines. Sourced directly from Honda, this part meets the same specifications as the original unit it replaces, ensuring the charging system on your GX440 engine performs exactly as intended. Confirm your engine's serial number against the fitment table before ordering to make sure part number 31715-Z2E-013 is the correct application for your unit.
Key Features
- Genuine OEM Charging Accuracy — Honda-sourced and built to the same electrical specification as the original, so the rectifier delivers the correct rectified output the GX440 charging circuit expects.
- Direct OEM Replacement — Replaces the original unit on GX440 horizontal shaft engines with no adaptation required, restoring the charging system to factory-correct operation.
- Serial Number Verification Recommended — Honda supersedes parts at production breaks; check your engine's serial number against the fitment table to confirm this rectifier is the right revision for your GX440.
- Protects Downstream Electrical Components — A correctly functioning rectifier keeps DC voltage clean and stable; a failed unit can overcharge or undercharge the battery and damage connected electrical loads.
The rectifier is a key component in the engine's charging circuit. It converts the alternating current produced by the engine's charging coil into the direct current needed to charge a battery or power DC accessories. When the rectifier fails, the battery will not charge correctly — leading to hard starting, erratic electrical behavior, or a completely dead battery over time. Replacing a faulty rectifier with a genuine Honda unit restores proper current flow and protects the rest of the electrical system.
