In some cases, if you kill the headlights, the battery will catch a charge. The headlights put the biggest drain on it. Eventually, the stator loses its charge over a longer period of time. Some bad stators will charge a little you might only notice it when the stator canвЂ™t keep up with the electrical systemвЂ™s pull. With a bad stator, the batteryвЂ™s charging capacity gradually drains. The big difference is that with a bad regulator, the battery doesnвЂ™t charge at all. The symptoms of a bad stator are similar to a bad regulator/rectifierвЂ™s symptoms- these parts work closely together, and a bad R/R can affect the Stator. In many cases, this was the handiwork of the aforementioned faulty regulator/rectifiers taxing the stator. Triumph Stator Failure ProblemsДЄnother issue with older Triumphs weвЂ™ve encountered is reports of bad stators. Triumph is always working on improving its models, and theyвЂ™ve 86вЂ™d the common problems such as a faulty regulator/rectifier unit. ItвЂ™s important to note that this issue has since been resolved. More owners found that MOSFET regulator/rectifiers had reliable improvement compared to the factory-installed SCR type regulator/rectifiers. In contrast, aftermarket parts were, in general, longer-lasting and better charging than the regulator/rectifiers that came from Triumph. They figured out that bad arts were leaving the factory and feared that replacing them with the same OEM part that had the problem could cause a repeat offense. Triumph Models with History of the Regulator/Rectifier Problem:Д«efore the Recall, owners took matters not their own hands and began upgrading /replacing their regulator/rectifier with an aftermarket one. By now, Triumph is well aware of the issue, and taking steps to rectify it wonвЂ™t be as mysterious as it once was. Inspecting the batteryвЂ™s condition and the voltage output are good first steps to indicating the regulator/rectifier on the bike was misbehaving.ДЄrmed with this information, you might be able to shed some light on the issues youвЂ™re having for the Triumph mechanic to ease their diagnosis. Check Engine Light or Battery Light Clicks On.ДЄfter noticing that the fuel gauge and other dash indicators showed incorrect values, mechanics and riders alike might initially chalk the problem up to electronics on the bike.Symptoms of a Failing Regulator/Rectifier on a Triumph: If youвЂ™re experiencing any of the following symptoms, contact your local Triumph dealer ASAP to get the appropriate upgrades. If youвЂ™re the owner of a bike that qualifies, be vigilant about the batteryвЂ™s condition. Once the battery is fully discharged, the motorcycle may stall. The regulator/rectifier can overheat and prevent the motorcycle from charging. Triumph is recalling certain model year 2006-2009 Street Triple, Street Triple R, and Daytona 675 motorcycles. In 2012 Triumph issued this recall statement: The downside to this is that if a part has an issue, the issues span across various Triumph models. They design machine-parts that can be cross utilized on a slew of completely different styles of motorcycles. Triumph has one of the strongest teams of engineers in the game. If your rectifier is bad, the battery will be damaged. The rectifier/regulator is the component responsible for sustaining the appropriate current. ThatвЂ™s where the rectifier/regulator comes in.

The AC flows through the rectifier/regulator, converting it to DC power at a consistent output.ДЄs engine speed accelerates, the stator outputs more and more power, and if left unregulated, it can overcharge the battery. The stator is a coil of wire in the engine case with a spinning magnet inside of it to generate an alternate current (AC). While cars use an all-inclusive alternator to keep their battery charged, a motorcycle uses a small charging system that starts with a part called the stator. To explain why itвЂ™s important to put this hazard on Triumph ownersвЂ™ radar, letвЂ™s first examine what the Regulator/Rectifier is and why itвЂ™s significant. Triumph estimated that between 2006-and 2009, over 10,000 Triumph Motorcycles left the factory with faulty Regulator/Rectifiers in them.
