Voltage Regulator Rectifier RM30409 for Honda NT 700 V, CBR 600 and CBR 1000 RR

Honda NT 700 V 2006-2012 / CBR 600 2004-2012 / CBR 1000 RR 2004-2012

Part RM30409 is a brand new voltage regulator rectifier supplied as a direct replacement for the original unit on the Honda NT 700 V Deauville, CBR 600 and CBR 1000 RR. It is a plug-and-play, direct fit item that installs without assembly or modification - the two plugs, five pins and five wires match the factory arrangement, and the fixation holes sit 65 mm apart to line up with the standard mounting bracket.

The regulator rectifier does two jobs at once. It rectifies the alternating current coming from the stator into direct current, and it regulates that output so the battery, lighting and engine management see a steady supply rather than a rising voltage as engine speed climbs. This replacement is built with a higher grade of electric components and an improved heat sink, which lifts both heat dissipation and charging capability above the original design. The manufacturer states the quality exceeds the OEM equipment, and every unit is tested before shipping.

The opposite connector for the main harness side is supplied with the unit. Burned and corroded harness connectors are a well known weak point on sportbike charging circuits and are frequently the real cause of an electrical fault that returns shortly after a regulator is replaced on its own. Fitting the new connector at the same time removes that risk.

Frequently Asked Questions

Does fitting this regulator require any modification?

No. RM30409 is a direct fit, plug-and-play replacement. The two plugs, five pins and five wires match the original layout and the fixation holes are 65 mm centre to centre, so the unit mounts and connects exactly as the factory part did. No assembly is required.

What is included?

The voltage regulator rectifier with its connectorised wiring, plus the opposite connector for the main harness side. That harness connector is included because burned or corroded connectors are a frequent cause of repeat electrical problems on these models.

How can I confirm the old unit has failed?

Check the voltage across the battery terminals with the engine running and warm. A functioning system should reach 14.5 V +/- 0.5 V. A charging voltage that never rises above battery resting voltage indicates the regulator is no longer charging, while a reading over about 15 V indicates it has stopped regulating. Heat discolouration or melted plastic around the plug is a further sign.

Will it cope with the output of a CBR 1000 RR charging system?

The unit is rated to a maximum charging current of 50 A, equivalent to 500 W, with open circuit voltage held below 15 V and an operating range of -20 C to 85 C. The improved heat sink is specifically intended to help it run cooler under sustained load.
