Mosfet Regulator Rectifier for Triumph and Ducati
Triumph 600, 650, 675, 955 and 1050 (1994-2018) and Ducati 749, 848, 999, 1000, 1098, 1099 and 1198 (2003-2015) - part number RM30507H
This is a brand new Mosfet voltage rectifier regulator, supplied as a direct replacement for the original unit fitted to a wide range of Triumph and Ducati models. It is a plug-and-play, direct fit part - easy installation, with no assembly required and no modification to the wiring loom. Every unit is tested before it is shipped.
Stop burning your regulator rectifier. It is time to update or replace the original with the advanced Mosfet type, which runs cooler than all OEM diode style regulators. This rectifier also has overheat protection - rather than burning up, it simply turns off for a while and cools off. The heat sink and the charging capability are both improved over the original, and a higher grade of electrical components is used throughout, so the quality exceeds the OEM equipment. The opposite connector for the main harness side is supplied with the unit.

Frequently Asked Questions
Does this fit without modification?
Yes. It is a direct replacement for the original unit, plug-and-play and direct fit, with no assembly required. The mounting holes are 75 mm centre to centre and the unit carries two plugs with seven pins in total.
What is included?
The Mosfet regulator rectifier and the opposite connector for the main harness side.
How do I know my old regulator has failed?
Check the charging voltage at the battery with the engine running. A healthy system holds around 14.5 V. A reading that never rises above resting battery voltage suggests the unit has stopped charging, and a reading above 15 V suggests it has stopped regulating and is overcharging the battery. Discoloured or melted connector pins and a regulator that is too hot to touch are further signs.
Why change to a Mosfet unit?
A Mosfet regulator runs cooler than the OEM diode style unit and adds overheat protection, so instead of burning out it shuts down until it has cooled. On models that are known for repeatedly cooking their regulator, that difference is the point of the upgrade.
