6M6-81960-A0-00 Voltage Regulator for Yamaha SuperJet 650 1990-1993

Voltage Regulator for Yamaha SuperJet 650

This voltage regulator replaces OEM part 6M6-81960-A0-00 and keeps your SuperJet 650 charging system within range so the battery stays topped up and the ignition keeps firing.

Overview

This voltage regulator is a direct replacement for the OEM 6M6-81960-A0-00 unit used on the Yamaha SuperJet 650. It controls the charging output from the stator so the battery receives steady voltage instead of spikes that can cook electronics or leave you stranded. Riders rebuilding a personal watercraft charging system will find this voltage regulator a straightforward swap for a failed or weak original.

Specs At A Glance

Good To Know

Q: How do I know the regulator is the problem? A: A battery that will not hold a charge or voltage that climbs too high while running often points to a failed regulator. Test charging output at the battery before replacing.

Q: Does this need any wiring changes? A: It uses the factory connector style, so it typically plugs into the existing harness without modification. Check your connector shape against the original before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
