ARCO VR003 Yamaha 15-20HP Voltage Regulator

The ARCO VR003 voltage regulator is intended for selected Yamaha four-stroke outboards in the smaller horsepower range identified by the supplier. It is a direct charging-system replacement for engines that use the Yamaha 6AH-series regulator. The component controls charging voltage in the compatible system rather than serving as a universal regulator for unrelated stators. Checking the original regulator number is recommended before disturbing the existing wiring.

Yamaha 6AH-81960-00-00 is the OEM reference listed for the VR003. That reference should match the removed component or the applicable engine parts catalog before installation. Compare the connector shape, mounting points, and harness routing with the original regulator. A visual match alone is not enough if the engine uses a different charging-system revision.

Inspect battery terminals, engine grounds, stator connections, and the regulator plug for corrosion or signs of overheating while the system is apart. Repairing poor connections at the same time helps avoid repeated charging faults. ARCO lists 12 months of materials-and-workmanship coverage for leisure use and 90 days for commercial or racing service. Verify charging output with the Yamaha service procedure after the replacement is installed.
