Voltage Regulator Rectifier for Yamaha FX 1, GP, SJ, Super Jet, VXR, Wave Blaster, Wave Raider, WaveRunner and XL

Yamaha 650, 700 and 760 cc personal watercraft, 1990-2017 - RMSTATOR part RM30922 - replaces OEM 6M6-81960-A0-00

This is a brand new aftermarket voltage regulator rectifier supplied as a direct replacement for the original unit fitted across the Yamaha 650, 700 and 760 cc personal watercraft range from 1990 onwards. It covers the FX 1, GP, SJ, Super Jet, VXR, Wave Blaster, Wave Raider, WaveRunner and XL families, and it is a direct fit part with no assembly required, mounting on the original 55 mm hole centres and reconnecting through the same four-wire, four-pin arrangement as the unit it replaces.

The regulator rectifier is the part of the charging circuit that turns the alternating current produced by the stator into direct current and then caps that output so the battery is not overcharged. This unit is specified to a minimum charging voltage of 14.5 V +/- 0.5 V, a maximum charging current of 50 A / 500 W and an open circuit voltage below 15 V, across an operating range of -20 °C to 85 °C. It is built with a higher grade of electric components, the quality exceeds the OEM equipment, and all products shipped are tested. On a craft that spends its life around water, applying dielectric grease to the connector at installation is recommended to keep the contacts dry and corrosion free.

Frequently Asked Questions

Does this fit without modification?

Yes. It is a direct replacement to your original unit, described as plug-and-play and direct fit with no assembly required. It uses four wires and four pins and mounts on 55 mm hole centres, matching the original installation on the listed Yamaha craft.

What is included?

You receive one new RM30922 voltage regulator rectifier unit, tested before dispatch. No additional hardware is listed for this part, so keep the original fixings and reuse them.

How do I know my old regulator rectifier has failed?

Measure the battery voltage with the engine running. A healthy system regulates to around 14.5 V. A reading that never rises above resting battery voltage means the craft is running off the battery alone and will not restart after a few outings, while a reading above 15 V means the output is unregulated and the battery is being cooked. This unit is specified at 14.5 V +/- 0.5 V with an open circuit voltage below 15 V.

Why is dielectric grease recommended?

Personal watercraft connectors sit in a damp engine bay and salt or lake water finds its way into the terminals. Packing the plug with dielectric grease at installation keeps water off the contact faces, which is why it is recommended for this part. It is a sensible step even on a unit that is otherwise plug-and-play.
