Voltage Regulator Rectifier for Yamaha XV250 Virago V Star 250

Product Overview

Replace a damaged, overheated, or unstable voltage regulator rectifier with this 5-pin 12V replacement unit, designed for select Yamaha XV250 Virago, V Star 250, XV125 Virago, and XV125S applications using OEM reference numbers 3DM-81960-00 and 3DM-81960-01.

The voltage regulator rectifier is an important part of the motorcycle charging system. It helps convert and regulate charging output before power reaches the battery and electrical components. A faulty regulator rectifier may cause weak charging, battery overcharging, repeated battery failure, dim lights, blown bulbs, unstable voltage, melted connectors, or electrical system problems.

This replacement unit is designed for a 12V DC system and features a 5-pin layout, three-phase full-wave rectifier design, regulated output range of 13.5V–14.5V, and 63mm mounting hole spacing based on supplied product data. Please compare your original regulator rectifier’s OEM number, plug shape, pin layout, mounting hole spacing, size, and charging system design before ordering.

Product Compatibility

Important Fitment Note:
This part is not selected by model name alone. Yamaha XV125, XV125S, XV250, XV250S, Virago 250, and V Star 250 models may use different regulator rectifiers depending on year, market, wiring harness, connector design, and charging system setup. Please confirm your original regulator rectifier matches the 5-pin connector, OEM reference number, mounting hole spacing, body size, and overall plug layout before ordering.

Specifications

Note:
The supplied size lists 90mm width. The correct inch conversion is approximately 3.54", not 5.54". Please confirm by comparing the product photo and original regulator before ordering.

• Also suitable for matching XV125 / XV125S Virago applications when the original regulator matches
• Three-phase full-wave rectifier design supports stable voltage conversion
• Helps regulate charging output and reduce voltage fluctuation
• Helps prevent overcharging, weak charging, battery drain, dim lights, and repeated battery failure
• Heat-resistant, vibration-resistant, and wear-resistant construction supports stable operation
• Direct replacement style, but original OEM number, plug shape, pin layout, and mounting distance must be checked before installation

OEM Cross Reference

Please use the OEM/reference number together with physical dimensions and connector layout for fitment confirmation. If your original regulator rectifier has a different plug shape, different pin count, different wiring layout, different mounting hole distance, different body size, or different charging system design, this part may not fit.
