Voltage Regulator Rectifier RM30Y08 for Kawasaki
Kawasaki 750 SS, ST, STS, STX, XIR and XI - 1991-1998
AC voltage regulator rectifier, supplied as a direct replacement for the original unit fitted to the Kawasaki 750 SS, ST, STS, STX, XIR and XI personal watercraft from 1991 to 1998. It is a plug-and-play, direct fit part - no assembly is required and no modification to the standard wiring loom is needed. The unit is built with a higher grade of electrical components than the original and uses an improved heat sink for better thermal performance and charging capability. The quality exceeds the OEM equipment, and every unit is tested before it is shipped.
This is an AC regulator rectifier, which controls the output of the charging coils and holds the electrical system at a safe voltage. On a personal watercraft the unit works in a hot, damp engine bay and is a common failure point. When it fails the usual symptoms are a battery that will not hold charge between outings, a battery that boils or gasses, or a charging voltage that either never rises above resting battery voltage or climbs well past 15 volts. This unit delivers a minimum charging voltage of 14.5 V +/- 0.5 V and a maximum charging current of 25 A / 300 W, with open circuit voltage held below 15 V and an operating range of -20 to 85 degrees Celsius.

Frequently Asked Questions
Do I need to modify the wiring to fit this unit?
No. This is a plug-and-play, direct fit replacement for the original unit and no assembly is required. It uses a single plug with 6 pins and 6 wires.
What is supplied?
One brand new aftermarket AC voltage regulator rectifier, part number RM30Y08, tested before dispatch. No additional connectors or fitting hardware are listed with this part.
How do I tell whether my old regulator rectifier has failed?
Measure the voltage across the battery terminals with the engine running. A healthy charging system should show around 14.5 V. A reading that stays at resting battery voltage suggests the unit is no longer charging, while a reading above 15 V suggests it is no longer regulating and is overcharging the battery.
Why are there two different wire lengths?
The harness on this unit uses wires of 160 mm and 200 mm so that each lead reaches its own connection point on the loom without being stretched or looped. This matches the original layout on these craft.
