How To Test A Stator


How do I know if my stator is bad?

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. via

How do you check a stator to see if it's good?

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. via

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. via

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. via

What causes a stator to go bad?

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. via

How do I test my alternator stator?

The stator is the fixed ring inside the alternator. To test the stator windings, with the ohmmeter on the lowest settings, test between each of the eyelets. There should be very low resistance. Test between the eyelets and the stator frame and there should be no connection. via

How many volts 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 (18x2). At 3000 RPM it should be 54 VAC (18 X 3). via

How do you test a rectifier with a multimeter? (video)

How much does it cost to replace a stator?

Stator & Rotor

A new stator and rotor set typically costs between $250 and $1,500. They are stationary and rotating parts of any system that generates electricity. When they stop working seamlessly, they need repair or replacement. via

Can you clean a stator?

Clean the stator by spraying or brushing on with mineral spirits and follow with wiping and blowing out with compressed air. Let it dry over night before applying your sealant. Mineral spirits will not damage your paint nor the winding coatings and is just a very good cleaning and degreasing product. via

Can I test a stator with a test light?

Probe each stator pin with the test light one at a time. If the bulb lights when connected between any of the stator plug pins and ground the stator is shorted and needs to be replaced. If you get proper AC voltage and the stator is not grounded (no light) the stator and rotor are good. via
