The reading of each combination should be the same (test leads 1-2, 2-3, and 3-1). The stator is a 290 watt stator. Are you able to test the stator wires at the regulator??? Static Stator Tests First perform the static stator tests. Step 3. With the ignition off, measure between the coils/phases by connecting the multimeter's leads to the three terminals in the stator's electrical connector. A low current correlates to high resistance. Before performing the test you will have to determine the proper stator range for your motor. However, the stator is much more prone to failure because it's made from thin strands of wire. Mercury Marine recommends that the switchbox(s) be replaced in the event of a stator failure. The display should show OL, for an open loop that indicates the coil hasn't shorted or grounded. Each of the following tests isolate the stator and rotor. Measure between the coils/phases by connecting the multimeter's leads to the three terminals in the stator's electrical connector. Measure between phases 1 and 2; between 2 and 3; and between 1 and 3. Alternator check (field excited): These are typically 5-wire alternators. We'll walk you through testing the stator, and we recommend watching the video above and printing the walk-through below reference. Step 4 Read the display on the LED screen.

You need a peak voltage tester to check the pulse generator (blue/yellow wire + and green/white wire -) and the peak voltage is 0.7V. Take your readings and check them in relation to your target readings, which … All Rights Reserved. Stator Turn Insulation Surge Test. Stator Checks/Rotor Check. This extremely small range requires special multimeters that aren't readily available at the hardware store. Step 2. Disconnect the stator wire from the main wiring harness. Test that the stator is generating power and test the wiring for shorts. A bad stator can cause a switchbox to fail. stream endobj Step 2. <> As stated above, a stator is one component of the motorcycle charging systems. Special discounts for companies in the powersports industry, Discounts for federal and most state and municipal agencies. These surge tests are normally done on new windings in the factory to detect faults. Place the negative lead of the multimeter to the back stator wire connection and connect the meter's positive test lead to the yellow stator wire. If a stator fails the Ohms Test, it is bad. The only way to know for sure which electrical component needs replacing is to test all three. Measure between phases 1 and 2; between 2 and 3; and between 1 and 3. The display should show OL, for an open loop that indicates the coil hasn't shorted or grounded. Therefore, it's not practical to perform a static test on such a close-ranged stator. Turn the voltmeter on and set it to AC volts. Example 2. This works for breaker point and CDI type ignition systems. Connect one of the multimeter's leads to a ground source, such as the body of the stator itself, and the other lead to each of the three terminals in the stator's electrical connector individually. óp¤Kîº=®[|7P§Ô»®Òz¶ÝnÍ2sh½¹d/%ùoqíé[*d The electrical system on your motorcycle, ATV or UTV is made up of the battery, the regulator/rectifier and the stator. ATV or UTV. The stator on the Ski-Doo is a stationary part of the engine, located near the spark plugs, that help create a spark in conjunction with the spark plugs that causes combustion in the gas engine. Place one meter lead in the connector and the second on the body of the stator Your meter should read “OL” or open line. Testing a Stator A stator test is either static or dynamic. 4 0 obj Once again, the exact range the stator should be within will vary between stator models and manufacturers. Measure between phases 1 and 2; between 2 and 3; and between 1 and 3. The dynamic test is performed while the stator is on the machine and the engine is running. Topics include test voltage, procedure, frequency and when to perform the various tests. Below you will find the data on how to test the stator. With the ignition switch in the “Off” position, disconnect the regulator from the stator. 3 0 obj © 2000-2021 Partzilla.com. How to Test a Motorcycle Stator When the rotor spins around the stator, the coils produce electricity as each magnet passes each wire coil. There is much discussion in the industry about how to properly electrically test AC stator and wound rotor windings. Set your multimeter to Ohms to check this. Watch the video above to see the full process of how to do a dynamic stator test. Ignition coil: This needs to be a fairly heavy duty coil. This test makes sure that the stator isn’t shorting out to the ground. endstream As with any electrical circuit, the stator in an ATV can be tested for continuity with a standard multimeter. Step 1. The static test is performed without the engine running, and the stator doesn't even need to be attached to the machine. With the ignition on and the engine running, measure between the coils/phases by connecting the multimeter's leads to the three terminals in the stator's electrical connector. But, in the general sense, there are some tests that you can do on almost any stator and tell a lot of whether it has failed or not. If they are different, your stator is defective. To test an ATV stator, simply follow these easy diagnosis flowcharts, or you can conduct the 3 following tests.. With the help of a DVA Peak Volt Adaptor, you can get a more accurate reading of your stator’s voltage and improve the likelihood of a correct diagnosis.. ATV stator – Ground Test. Higher current correlates to low resistance, and the meter needle moves more to … The meter needle settles on the left-hand side of the dial. Example 1.

Test the AC voltage from each of the stator's windings with the Grizzly's engine running. A stator test is either static or dynamic. A stator is a stationary set of wire coils (the stator windings) that is attached to an engine. The stators found in motorcycles, ATVs and UTVs are generally 3-phase stators. With the connector unplugged, you can test the stator for both resistance and voltage. How to Test the Stator on a Motorcycle, ATV or UTV. The number one test is to ground it out. Locate the stator wire under the flywheel. The … Do this by either consulting your owner's manual or contacting a marine repair shop. Measure between phases 1 and 2; between 2 and 3; and between 1 and 3. To perform a dynamic test on your stator: Change the multimeter setting to AC volts, and start the machine up. You should be aware that different manufacturers are going to have different tests, different readings, and different styles of stators. Measure between the coils/phases by connecting the multimeter's leads to the three terminals in the stator's electrical connector. To begin, you should first check for continuity from the terminal tabs of the connector and then see if anything goes to the ground. The reading between the terminals should increase as the RPM increases. I previously tried using … The exact range the stator should be within will vary from model to model, and manufacturer to manufacturer. NOTE: For the following examples, click on each image to watch the corresponding video portion. If the multimeter is picking up a reading, it means your stator needs to be replaced. The static test is performed without the engine running, and the stator doesn't even need to be attached to the machine. If the voltage readings don't change from when the ignition was off to when the engine was running, the stator is faulty and will need to be replaced. ÿØÿà JFIF ÿÛ C
2!=,.$2I@LKG@FEPZsbPUmVEFdemw{N`}s~|ÿÛ C;!! Aside from wear over time, not much can go wrong with the rotor. Turn off your motorcycle. Learn how to properly test your magneto, stator or pickup coils. Once again, measure between phases 1 and 2, 2 and 3, and 1 and 3. Set your meter for ohms measurement and test the resistance between A-B, B-C, and A-C. The stator/rotor assembly is collectively known as an alternator. In this example, a Honda stator with a range of 0.1 ohms to 1 ohm is being measured. Step 1. When the positive and negative leads are touched together, the display will read 0 or close to 0, because the loop is now closed. This means the current circuit is open and isn't shorted or grounded. If the stator fails any of the static tests, it will need to be replaced with an OEM stator for your motorcycle, ATV or side-by-side brand. endobj If the resistance measured falls within the range given in the Kohler owner's manual for the specific size and model engine, the stator is good. Sounds like the reg isnt getting any juice from the stator. 1616 In the last example, a Yamaha stator with a range of 0.1 ohms to 0.132 ohms is being measured. If your electrical system is failing to charge, the problem lies in one of those three components. With the multimeter's positive and negative leads apart, the display will show "OL" (open loop). If all those tests check out, then the regulator/rectifier has to be the problem. There should be no reading between the terminals. Sounds like there either not connected or broken. The static stator test involves measuring from coil to coil — or phase to phase — within the stator, and also measuring from each coil/phase to ground. ;|SFS||||||||||||||||||||||||||||||||||||||||||||||||||ÿ öò" ÿÄ ÿÄ ÿÚ óÚvh ¦ÐÆRÚ¤ÑNYI¤!¡1Líõx{f Q4$Á&Ö:ÅÊùÞg»âÙW(`RÒ h¦Ë ¦ §I i é$¼Ø5Ñ

õæ7 V C¥¡4Ô )0 Instead, you'll have to perform a dynamic test. When you have a problem with the electrical system in which the engine on your motorcycle, ATV or UTV won't run, you'll have to do a static test. If you can verify you have stator voltage to the regulator on all 3 legs and nothing coming out then yeah VR is NG!! I tested mine and I had 0.2 ohms can anyone tell me a sure shot way to test this stator and what is a good reading and a bad or time to replace reading? Example 3. There should be a positive reading between the terminals. Two of the stator tests are passive resistance or continuity tests. The surge tests are hipot tests used to check the integrity of the interturn as well as the capability of the ground wall insulation to withstand steep transients that are likely to be encountered in normal service. NOTE: You'll need a multimeter to test a stator. First we will test for resistance or shorts between the stator legs themselves. First, ensure the on/off switches are on and that the remote is in the on position (if equipped with remote). Motorcycle alternator refers to a collection of components that includes the stator, but also includes magnets and a rectifier/regulator (devices that convert AC current to DC current and maintain steady output). Set the multimeter to ohms. These consist of three separate windings wrapped around a series of points that circle the unit, with the ends of the three windings leading to an electrical connector. In simple terms, the stator generates the electricity that powers the battery in a motorcycle, ATV or side-by-side, and is therefore responsible for powering the vehicle itself.
