Can you test a motorcycle stator?
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 rectifier is bad?
Key Signs to Look For
You won’t have any trouble diagnosing the faulty regulator rectifier if the battery is the cause. You’ll note signs right away like poor starts, fluctuating meter readings, and dimmed headlights. around 13 volts, the bike will start to drain the battery.
What makes a stator go bad on motorcycle?
To answer why stators fail, it is because the coating on the windings breaks down, usually because of heat, causing a short which can also burn the fine wire of the winding in two at the short causing an open circuit. The way to prevent failures is to prevent the heat.
Will a bad stator drain a battery?
Will a bad stator drain a battery? As far as the battery, yes a bad stator/regulator can destroy a new battery. If it’s run at a very low voltage without being recharged then it can be destroyed. … In most cases if we replace a stator or regulator the battery has to be changed as well as it won’t hold a charge.
How many volts should a motorcycle stator put out?
The output from the stator on most modern bikes is three phase (hence the 3 wires) alternating current at a peak voltage well over the 12-14V DC voltage that your electrical system requres.
Can a stator go bad from sitting?
Stators do not go bad from sitting unless the mag housing is full of water.
Will a bad rectifier damage a stator?
If the rectifier/regulator failure results in too low resistance the stator probably will burn (too much current). If I disconnect the rectifier/regulator the voltage will go up, but how high? Is it possible that the voltage will go high enough to destroy the isolation?
What causes stator to fail?
When a stator fails, it is largely due to the degradation or aging of its insulation through external occurrences and materials being introduced into its system.
