The Honda 31700-ZE8-901 Silicon Rectifier Assembly is a genuine OEM component designed for GXV270, GXV340, and GXV390 vertical shaft engines. As a direct OEM replacement, this rectifier assembly is manufactured to Honda's original specifications, ensuring the charging system performs exactly as intended. This part is compatible across the GXV270, GXV340, and GXV390 engine series — confirm your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks. When the charging system is operating correctly, the battery and any electrically dependent accessories on the equipment receive a steady, well-regulated DC supply.
Key Features
- Genuine OEM Charging Performance — manufactured by Honda to deliver the same AC-to-DC conversion rate as the original unit, maintaining correct voltage output across the engine's charging circuit
- Direct OEM Replacement — engineered to drop in as a like-for-like swap on GXV270, GXV340, and GXV390 vertical shaft engines, using the original mounting points and wiring connections
- Broad GXV-Series Coverage — a single part number covers the GXV270, GXV340, and GXV390 engine family; verify your serial number against the fitment table to confirm the correct application
- Protects Battery and Electrical Accessories — a failed rectifier allows unregulated AC voltage into the DC circuit, damaging the battery and any connected accessories; replacing a faulty unit restores clean, stable output
The Silicon Rectifier Assembly converts the alternating current (AC) produced by the engine's charging coil into the direct current (DC) needed to charge the battery and power any DC electrical loads on the equipment. Without a functioning rectifier, the raw AC output from the stator cannot be used by the battery or DC accessories, and the charging system effectively stops working. When this component fails — typically through heat fatigue or overload — the battery will no longer charge, and voltage-sensitive accessories may be damaged; replacing the rectifier assembly restores full charging system function.
