The Honda 31700-ZE8-003 Silicon Rectifier Assembly is a genuine OEM component designed for GXV270, GXV340, and GXV390 vertical shaft engines. As a direct Honda OEM replacement, this rectifier assembly matches the original specification exactly, ensuring it integrates correctly with the engine's charging circuit without adaptation. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and fitment can vary within a model series. This part is backed by Honda's OEM supply chain, giving you confidence that you are installing the correct component for your application.
Key Features
- Genuine OEM Charging Accuracy — sourced directly from Honda, this Silicon Rectifier Assembly meets the original electrical specification for correct DC output voltage and current handling on GXV-series engines
- Direct OEM Replacement — engineered to drop into the existing charging circuit of GXV270, GXV340, and GXV390 engines using the original mounting and wiring connections
- Vertical Shaft Engine Fitment — built specifically for the GXV270, GXV340, and GXV390 vertical shaft engine series; verify your serial number against the fitment table to confirm the correct supersession for your unit
- Restored Charging Performance — a failed rectifier leaves the battery unable to hold charge and connected electrical accessories without power; replacing this assembly restores proper DC rectification and stable charging output
The Silicon Rectifier Assembly converts the alternating current produced by the engine's charging coil into the direct current required to charge the battery and power any DC accessories on the equipment. Without a functioning rectifier, AC voltage passes uncorrected into the electrical system, which prevents the battery from charging and can damage voltage-sensitive components. When this assembly degrades or fails, symptoms typically include a battery that drains quickly, erratic electrical behavior, or accessories that cease to function — replacing it restores normal charging system operation.
