How much voltage should a stator put out?
For example a 32-amp stator should put out 18 volts AC (VAC) per each 1000-RPM. At 2000 it should be 36 VAC (18×2). At 3000 RPM it should be 54 VAC (18 X 3).
Why does a stator need a voltage regulator?
A battery requires constant voltage of 14.4 volts to be charged efficiently as higher voltage will cause the battery to boil. The regulator acts as a filter between the stator and the battery to ensure the battery receives the proper voltage by sending any extra to the ground.
What does a rectifier do on a stator?
The regulator acts as a filter between the stator and the battery to ensure the battery receives the proper voltage by sending any extra to the ground. The Rectifier The rectifier part of the voltage regulator rectifier converts the stator’s alternating current (AC) into direct current (DC) that can charge the battery.
What does a stator do on an ATV?
The alternative current (AC) produced by the ATV’s stator cannot be directly used by electrical components. Before it can be used in the vehicles ignition and charging systems, the current must be converted to direct current (DC) and regulated so there is no peak in voltage. That is what a voltage regulator rectifier does.
How much voltage does a stator produce at full throttle?
The regulator part of the voltage regulator rectifier helps create a smoother more constant flow of electricity. As engine RPMs increase, the stator produces more voltage which is usually higher and very irregular. At full throttle, some stators can produce up to 120 volts of electricity.
How does a stator work on an ATV?
Think of it like your car’s alternator. Stators can look quite different depending on the brand of ATV and model, but in general, they consist of an iron core, wire coils, and a cable that allows the stator to be connected to the voltage regulator.
How can I tell if my stator needs to be replaced?
This test makes sure that the stator isn’t shorting out to the ground. Your meter should read “OL” or open line. If the multimeter is picking up a reading, it means your stator needs to be replaced. Repeat this test for each of the windings.
What can cause a regulator rectifier to fail?
When it overheats, the component could fail fast. Other common causes for regulator rectifier failure involve the battery. To have voltage, the battery needs to have a reliable ground connection. If the link is bad and the voltage is faulty, this can cause the regulator rectifier to run hotter than usual.
How many wires does an alternator stator coil have?
Your bike’s alternator stator coil produces AC voltage. Generally, motorcycles feature a three-component system containing three wires that link the stator to the regulator rectifier. Some bikes have single-phase designs because they cost less to manufacture, in which case there would be two wires rather than three.
