XV250 Voltage Regulator Rectifier
🔧 Regulator Rectifier · Voltage Regulator · Rectifier Assembly
For Yamaha XV250 2V49FMM 250cc engine · High-quality replacement · Ready to install
This is a high-quality voltage regulator rectifier for the Yamaha XV250 2V49FMM 250cc engine. The voltage regulator rectifier is a core component of the motorcycle charging system, responsible for converting AC power from the generator to DC power and stabilizing the voltage between 13.5-14.5V to charge the battery and power all electrical devices.
Manufactured with premium electronic components and efficient heat dissipation design, this product offers excellent voltage regulation and durability. When the original rectifier fails, causing battery drain, flickering lights, or unstable voltage, this product is the ideal replacement choice.
✨ Core Functions: AC to DC conversion · Voltage stabilization · Battery protection · Ensures proper electrical system operation
This voltage regulator rectifier fits the following vehicles:
Engine Type: Yamaha XV250 2V49FMM 250cc and other platform-compatible engines
📌 Compatibility Note: This rectifier fits the Yamaha XV250 and numerous other vehicles using the same 250cc engine. Please verify your vehicle model and connector type before purchase. Images are for reference only; actual product may vary.

- Battery drain: Battery frequently dead, won't start, even with a new battery.
- Lighting issues: Headlight dim, flickering, or unstable brightness.
- Over-voltage: Excessive battery electrolyte consumption, bulbs burning out frequently.
- Charge indicator abnormal: Charge light not on, always on, or flickering.
- Rectifier overheating: Rectifier unit abnormally hot to touch, burning smell.
If you experience these issues, inspect the charging system, especially the voltage regulator rectifier.
- Premium electronic components: High-quality SCR/MOSFET for precise voltage regulation and fast response.
- Efficient heat dissipation: Thickened aluminum heat sink effectively reduces operating temperature, extending service life.
- Water and dust resistant: Potting compound treatment, shockproof, waterproof, dustproof - adapts to harsh environments.
- Direct replacement: OEM specification design, plug-and-play connectors, no wiring modifications needed.
- Protection features: Built-in over-voltage protection, over-current protection, short circuit protection for safety.
🔧 Installation Tips
1. Disconnect the battery negative terminal before installation for safety.
2. Verify that the new rectifier connector type matches the old one and wire colors correspond.
3. The rectifier must be mounted in a well-ventilated location to ensure effective heat sink cooling.
4. Secure firmly to prevent vibration damage.
5. After installation, start the engine and measure battery voltage - should be 13.5-14.5V at idle, stable when revving.
AC Input (Yellow): 3 yellow wires - Connect to generator three-phase output
DC Positive Output (Red): Connect to battery positive and vehicle electrical system
DC Negative/Ground (Black/Green): Connect to battery negative or frame ground
Voltage Sense (Brown/White): Monitors battery voltage for regulation control
Note: Wire colors may vary slightly by model; refer to your vehicle's wiring diagram.
- Please verify that this part fits your specific vehicle model and year. Many vehicles share similar names but use different components depending on year or market region.
- We strongly recommend cross-checking with your vehicle's owner's manual or contacting us for confirmation before placing your order.
