What causes a stator to fail?
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.
Where is my stator?
The stator is the coil of wire housed inside the engine case. A magnet on a shaft spins within the stator, creating alternating current (AC).
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. It actually happens all the time. 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.
Can a stator be fixed?
Fixing a stator usually involves unwinding and cleaning the original stator core, then rewinding it with a machine or carefully by hand. It starts with looking at the coil heads for damaged or burned wires, then cutting out the protective rubber coating from damaged coils.
Can a stator go bad from sitting?
Stators do not go bad from sitting unless the mag housing is full of water.
Can a bad stator drain a battery?
How can I tell if my stator connector is defective?
Ohms Test. You will need a multimeter set to Ohms for this test. Test every lead of the stator’s connector and note the readings. The reading of each combination should be the same (test leads 1-2, 2-3, and 3-1). If they are different, your stator is defective.
What’s the best way to test a stator?
Put your multimeter to AC Volts and start you vehicle. As with the Ohms test, test between each lead of the connector (1-2, 2-3, 3-1) and note the readings.
What are the symptoms of a bad motorcycle stator?
What are the symptoms of a bad motorcycle stator? The most obvious symptoms of a bad motorcycle stator include no spark, weak spark, or intermittent spark (also known as misfiring). Hard starts and a poorly running engine can also be clues that your stator needs to be rebuilt or replaced.
How to diagnose a bad stator on a Polaris Sportsman?
How to diagnose a bad stator? Consider the following diagram : This is for a Polaris sportsman 700 2003 ATV On the top right corner, you have the information to check if the stator function properly. For the first three coils, everything pass.
