Regulator rectifier for the Kawasaki KZ's. Battery not charging? Might be time to replace your rectifier regulator. Some models had a separate regulator and rectifier from the factory, remove both of those parts and install the new unit. Since this is replacing both parts, it will be necessary to adapt the stock wiring to connect to this unit. Unlike many other units, this is designed to work with lead acid based, gel and lithium batteries. The battery must be fully charged and in perfect working order before installing a new regulator rectifier.
This unit has a very consistent output and runs cooler than the original part due to the modern heat sink. The stable voltage output across the RPM range keeps the battery charged so you can ride with confidence!
All units are tested prior to shipping for quality assurance. Includes industry-leading 1 year warranty.

Replaces Kawasaki Part Numbers: 21066-1011, 21066-1008
Note: Corroded / loose / damaged wiring is a common cause for charging system issues, make sure all connections are clean and secure. If the stock connector is brittle or melted and the terminals are corroded, it's best to replace them before installing the new part. This unit might not mount where the stock part was, check dimensions above.
Note: It is strongly recommended to isolate the charging issue prior to replacing the regulator / rectifier. With a bad battery, stator or wiring issues, a new RR will not charge the battery. A faulty stator or wiring can cause damage to the RR.
