RM30001 Voltage Regulator Rectifier

Kawasaki Ninja, Eliminator, Vulcan, Zephyr and Bayou 1984-2023

The RM30001 is a brand new voltage regulator rectifier supplied as a direct replacement for the original unit fitted to a long list of Kawasaki machines - the Ninja, Eliminator, Vulcan, Zephyr and Bayou families across model years from 1984 right through to 2023. It is plug-and-play and a direct fit, so nothing has to be cut, spliced or adapted.

No assembly is required. The unit uses a higher grade of electrical components than the factory part, combined with an improved heat sink and better charging capability, which is exactly where the original diode style regulators tend to give trouble as they age. The single six pin plug mates with the standard Kawasaki connector, the housing measures 79 by 89 by 27 mm, and the two mounting holes sit 70 mm apart centre to centre.

Frequently Asked Questions

Does it fit without modification?

Yes. The RM30001 is a direct replacement for the original unit, plug-and-play and direct fit, with no assembly required. The single six pin plug and the 70 mm mounting hole spacing match the factory part.

What is included?

One RM30001 voltage regulator rectifier, ready to bolt on and plug in. No additional parts or assembly are needed for a standard replacement.

How do I know my old unit has failed?

A flat or repeatedly discharged battery, charging voltage at the battery that never settles near 14.5 V, an over-charged and gassing battery, dim or flickering lights, and a regulator body that becomes too hot to touch are all classic symptoms of a failed regulator rectifier.

How much charging capacity does it handle?

The RM30001 is rated to a maximum charging current of 35 A / 400 W, with a minimum charging voltage of 14.5 V plus or minus 0.5 V and an open circuit voltage below 15 V. It operates from -20 C to 85 C.
