What's wrong?
The regulator/rectifier on affected 2006-2009 Triumph Daytona 675 and Street Triple motorcycles is part of the charging system. It takes electricity from the alternator, changes it into direct current the battery can store, and keeps voltage at a usable level for the ignition, lights, and other electrical parts.
On affected motorcycles, the regulator/rectifier can overheat and stop the battery from charging while the engine is running. The motorcycle then keeps using stored battery power until the battery is fully discharged. Once that happens, the ignition and fuel systems lose the electrical supply they need, and the motorcycle can stall.
There is no warning sign before failure. The first notice can be a weak battery, electrical loss, or the engine stalling after the charging system has already stopped keeping the battery charged.
Who's affected?
Covers both Daytona 675 and Street Triple motorcycles across the 2006, 2007, 2008, and 2009 model years, all using the same alternator, generator, and regulator component.
