The RM30502 is a brand new aftermarket voltage regulator rectifier supplied as a direct replacement for the original Suzuki unit fitted to the Boulevard C50 and M50, GSXR 600 and 750, V-Strom 650 and LTA 700 X between 2001 and 2019. It is plug-and-play and a direct fit, so installation is easy and no assembly is required.
Built with a higher grade of electrical components and an improved heat sink that also raises charging capability, its quality exceeds the OEM equipment it replaces, and every unit shipped is tested. The opposite connector for the main harness side is included as well, since that plug is very often melted, corroded or defective on higher mileage machines and is a major cause of repeat electrical faults. The unit is rated to 50 A / 500 W and cross references to a long list of Suzuki part numbers including 32800-41F10.

Frequently Asked Questions
Does it fit without modification?
Yes. The RM30502 is a direct replacement for the original unit, plug-and-play and direct fit, with no assembly required. Mounting holes are 80 mm apart centre to centre and the two plugs carry the same seven wires as the factory part.
What is included?
One RM30502 voltage regulator rectifier with seven wires on 260 mm and 250 mm leads across two plugs, the connector, and the opposite connector for the main harness side so a damaged loom plug can be renewed at the same time.
How do I tell my old regulator rectifier has failed?
Typical symptoms are a battery that will not hold charge, charging voltage that never settles near 14.5 V at the battery, an over-charged battery that boils or swells, lights that dim or flicker with engine speed, and a regulator that runs far too hot. Melted or discoloured connector pins point to the same fault.
Why does the harness side connector matter so much?
Heat and corrosion in the loom plug are among the most common causes of repeated regulator failure. Fitting a new regulator into a burnt connector simply repeats the problem, so the matching harness side connector is supplied in the box to let you repair that side properly at the same time.
