The RM30104 is a brand new aftermarket voltage regulator rectifier for the Triumph 675 triple range, covering the Daytona 675 and 675R and the Street Triple 675 and 675R from 2006 to 2020. It is a direct replacement for the original unit - plug-and-play, direct fit and easy to install, with no assembly required. A higher grade of electrical component is used throughout and the quality exceeds the OEM equipment. Every unit is tested before it is shipped.
The regulator rectifier turns the alternating current from the stator into the direct current the battery and electrical system need, then holds that output at a controlled level. When it fails, the machine either stops charging altogether or overcharges and destroys the battery, and on the 675 triples a failing regulator is one of the more common causes of a bike that will not restart after a ride. This unit is rated at a maximum charging current of 50 A / 500 W, a minimum charging voltage of 14.5 V plus or minus 0.5 V, an open circuit voltage below 15 V, and an operating range of -20 C to 85 C. The body measures 80 mm wide by 103 mm long by 33 mm high with 75 mm between the fixation hole centres, and it carries two plugs with seven pins across seven wires of 350 mm.

Frequently Asked Questions
Does this fit without modification?
Yes. It is a plug-and-play, direct fit replacement for the original unit with no assembly required. The mounting holes are 75 mm apart centre to centre and the unit uses two plugs with seven pins across seven 350 mm wires, so those figures make it easy to confirm the match against your existing part.
What is included?
The voltage regulator rectifier unit, tested before dispatch. No assembly is required and it is supplied ready to fit.
How do I know my old regulator has failed?
Measure across the battery terminals with the engine running. A healthy charging system should reach a minimum charging voltage of 14.5 V plus or minus 0.5 V and hold below roughly 15 V. A reading that never rises above resting battery voltage means the unit has stopped charging; a reading well above 15 V means it has stopped regulating and the battery will be ruined. A bike that needs a jump start after every ride is the classic symptom on the 675 triples.
Does the same part cover both the Daytona and the Street Triple?
Yes. Triumph used the same regulator specification across the Daytona 675 and 675R and the Street Triple 675 and 675R within the years listed, which is why both T1301234 and T1300823 appear in the cross reference. Check the number on your existing unit against that list to confirm.
