Why does my rectifier keep going out?

Other common causes for regulator rectifier failure involve the battery. To have voltage, the battery needs to have a reliable ground connection. Things like poor grounding, a loose or weak battery, and a worn battery connection can all lead to regulator rectifier failure.

Why does a rectifier burn?

There are different reasons why the regulator rectifier fails. Ground connections are important for good voltage, and if there is faulty voltage, the regulator rectifier can run hot. Bad grounding, corroded battery connection and poor or loose battery connections will cause faulty voltage.

Can a bad stator damage a rectifier?

Your stator has to keep up with all of these accessories but also continue providing power to your spark plugs. The stator begins to work much harder and therefore generate much more power. Over time this can wear out your stator. You can actually burn the stator and rectifier by overloading it.

Will a motorcycle run with a bad rectifier?

A rectifier converts alternating current (AC) to direct current (DC) to charge the battery. Since motorcycles require battery power to start them up, a bad rectifier will eventually result in the motorcycle not able to start.

How hot should a regulator rectifier get?

Too hot to touch is not really a good temperature reading. That is probably around 140 degrees F or 60 C. Of course, that is also too hot for most electronic components which are normally rated to a max of 50 deg C.

How do I know if my stator or rectifier is bad?

Insert each probe into a stator socket. You should read around 0.2 to 0.5 ohms. If you show an open circuit with the “Open” or infinity reading or have higher resistance, then the stator is bad and you must replace it. If these tests all produce positive results, then the stator itself is good.

How do I know if my stator or voltage regulator is bad?

Another way you can tell the voltage regulator is bad is when the car lights keep dimming or flickering. After all, the voltage regulator is supposed to keep the power flowing to the lights, so it’s no surprise that those lights don’t work right anymore once this part goes bad.

What are the symptoms of a faulty rectifier?

Probably, the most common symptom associated with a bad regulator is flickering, dimming, or pulsing lights. To be more specific, you may notice that the vehicle’s: Headlights fluctuate between bright and dim, without you doing anything.

Why is my regulator overheating?

The bigger the difference between the input and output voltage, the more heat the regulator generates. If the input voltage is so much higher than the output voltage, the regulator will generate more heat than it can dissipate and it will overheat. Some regulators shut down when they overheat. But others keep working.
