Question: Does Rectifier need to be grounded?

The stock rectifier doesnt need a case ground. But, some rectifiers need a frame connection to aid the heat sink function.

How do I know if my rectifier is bad?

Key Signs to Look For You wont have any trouble diagnosing the faulty regulator rectifier if the battery is the cause. Youll note signs right away like poor starts, fluctuating meter readings, and dimmed headlights. around 13 volts, the bike will start to drain the battery.

Are stators grounded?

Premium Member. The stators are not grounded, if any of the wireseverdo ground the stator is dead. The stator body is bolted to the engine case, thats all.

Does a voltage regulator have a ground wire?

Registered. Yes the regulator must ground to the chassis for proper operation.

Why does my rectifier get hot?

Its normal for an OEM shunt-type regulator/rectifier (RR) to get quite hot — especially when the load being drawn by the electrical system is low. The RR is simply converting excess stator output wattage (that isnt needed to run the bike and charge the battery) to heat. Thats why there are cooling fins on the RR.

What does a faulty rectifier do?

Depending on the location of the regulator rectifier, the part can easily overheat. 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.

How do you test a rectifier?

What happens if stator is grounded?

When the stator shorts to ground your charging voltage drops below the normal charging spec. the drop in voltage varies so its not like your loosing 1/3 voltage every time one coil is grounded. you could have 12volts at the battery or 11 volts with one coil shorted. you just wont have 13.5 or better.

How hot does a rectifier get on a motorcycle?

Re: how hot is the regulator/rectifier supposed to get while running? I would say that if you can place your hand there and tolerate it, youre fine (about 115* to 125*F) If you get pain while touching it briefly, its in need of some air, and could be a problem >130*F.

How do I fix my rectifier?

Will a motorcycle start 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.

Can a bad regulator rectifier cause no spark?

A bad regulator/ rectifier will result in a dead battery, and once the battery is competely dead you will not get a spark.

Can a stator be repaired?

Stator Replacement In many cases a new stator is the safest, most cost-effective solution for an electrical system breakdown. Because repairing stators can be an intricate and detail-intensive process, replacing failed stators with an entirely new part can be a much easier route, depending on the specific motorcycle.

What is the difference between a positive ground and a negative ground?

For use in a positive ground system, a conventional automotive battery is simply installed backwards, meaning the positive terminal is the ground and the negative terminal is the live side.

Do motorcycle coils need to be grounded?

The coil does not need an electrical ground, but it does need a thermal ground for heat dissipation, meaning that the ground could be compromised by paint etc. and still serve its purpose as a thermal point of dissipation.

How hot should a rectifier get?

Re: how hot is the regulator/rectifier supposed to get while running? I would say that if you can place your hand there and tolerate it, youre fine (about 115* to 125*F) If you get pain while touching it briefly, its in need of some air, and could be a problem >130*F.

Why is my voltage regulator getting hot?

Why is the voltage regulator heating up? The greater the difference between input and output voltage or the greater the current, the more heat will be dissipated by the regulator. This means linear power regulators are not very efficient at regulating voltage, since so much energy is wasted as heat!
