MOSFET Voltage Regulator Rectifier - RM30603
Buell 1125 R and Buell 1125 CR - 2008-2010
A brand new MOSFET voltage rectifier regulator for the Buell 1125 R and 1125 CR. Stop burning your regulator rectifier - it is time to update or replace your voltage regulator with the advanced MOSFET type. A MOSFET unit runs cooler than all OEM diode style regulators, and this rectifier also has overheat protection: rather than burn up it will simply turn off for a while and cool off before returning to normal operation.
It is a direct replacement to your original unit, plug-and-play and a direct fit, so installation is easy. The quality exceeds the OEM equipment, and it is built with a higher grade of electric components along with an improved heat sink and improved charging capabilities. All shipped products are tested before dispatch. The unit is rated to a maximum charging current of 25 A / 300 W, which matches the output requirement of the 1125 charging system, and it replaces Buell part number Y0302.1AMC.

Frequently Asked Questions
Do I have to modify anything to fit it?
No. This is a direct replacement to your original unit and is plug-and-play, so it is a direct fit with easy installation. It has 2 plugs, 5 pins and 5 wires, with wire lengths of 225 mm and 260 mm, and the fixation holes are 82 mm apart centre to centre.
What is included?
You receive the RM30603 MOSFET voltage regulator rectifier, measuring 80 mm wide by 100 mm long by 26 mm high. All shipped products are tested before dispatch.
How do I know the old regulator rectifier has failed?
With the engine running, the charging system should reach a minimum charging voltage of 14.5 V +/- 0.5 V at the battery and open circuit voltage should stay below 15 V. Readings that fall short leave the battery flat; readings that overshoot will cook it. Overheating symptoms and burnt connector pins on the original unit are also strong indicators.
What is the output rating of this unit?
Maximum charging current is 25 A / 300 W, with an open circuit voltage below 15 V and an operating temperature range of -20 C to 85 C. It replaces Buell part number Y0302.1AMC, so checking the number on your original part is the surest way to confirm fitment.
