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.

Fitment FAQ
Will this part fit my specific model and year?
This regulator rectifier is designed for select Yamaha XV250 Virago, XV250S Virago, and V Star 250 applications using OEM references 3DM-81960-00 and 3DM-81960-01. It may also fit select XV125 Virago and XV125S applications when the original regulator matches. Please compare your original part number, plug shape, pin layout, body size, and mounting hole spacing before ordering.
Do I need to match the OEM part number?
Yes, matching the OEM or reference number is strongly recommended. This regulator rectifier replaces Yamaha 3DM-81960-00, 3DM-81960-00-00, 3DM-81960-01, and 3DM-81960-01-00. However, OEM number alone is not enough. Please also confirm the 5-pin connector, 12V system, plug shape, mounting hole spacing, regulator body size, and charging system type.
What models or situations does this part not fit?
This part does not fit Yamaha Virago, V Star, XV125, XV250, cruiser, scooter, ATV, or other Yamaha models that use a different regulator body, different pin count, different plug shape, different wiring layout, different mounting distance, or different charging system design. It is also not a replacement for the stator, battery, starter relay, fuse box, ignition coil, CDI / ECU, or complete wiring harness.
What should I check before ordering?
Before ordering, please check your motorcycle make, model, year, market version, OEM regulator number, plug shape, pin count, wire layout, mounting hole spacing, body length, width, thickness, and charging system type. For best fitment, compare the product photos and specifications with your original regulator rectifier before purchase.
