AC Voltage Regulator Rectifier RM30Y04 for Sea-Doo
Sea-Doo 580 GT, GTS, GTX, SP, SPI, XP - 650 SPX, XP - 720 GTI, GTS, HX, XP - 1990-2001
Brand new improved AC voltage regulator rectifier, supplied as a direct replacement for the original unit fitted across the Sea-Doo 580, 650 and 720 personal watercraft ranges from 1990 to 2001. 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, the quality exceeds the OEM equipment, and every unit is tested before it is shipped.
This is an AC regulator rectifier, the type used on these Sea-Doo hulls to control the output of the flywheel charging coils and keep the electrical system at a safe voltage. When the original unit 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 20 A / 150 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 four plugs, 4 pins and 4 wires of 160 mm, matching the original connections.
What is supplied?
One brand new improved AC voltage regulator rectifier, part number RM30Y04, 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 is the output rating lower than on other regulator rectifiers?
This part is matched to the charging system used on these Sea-Doo hulls, which is rated at 20 A / 150 W. A higher rated unit is not required and the output figure reflects the original specification for these craft.
