    Multimeter reading help

    I am having to test a stator.
    Testing between 2 of the yellow stator wires in turn and running revs to 5000k to check if the stator voltage readings in AC at setting 200.

    If the result is under 50v I am informed the unit is faulty.
    It shows 0.5 at 200 setting as per pic and n all wires.

    I simply don't know what 0.5 means in units ?

    Is 0.5v as is ? Or is it measured in other units ?
    Help ?

    If it is 0.5 in reality my new stator I bought is faulty and explains everything !!!!!!!!!

    You don't want to test between the wires for voltage, only to see if there's a short (no resistance) It looks to me what you're seeing is a voltage difference between two windings which you would expect to be pretty close in a functional stator.

    Put the red probe on one of the stator wires and the other on a GOOD KNOWN GROUND such as directly on the battery negative terminal. Make sure the selector on the meter is set to read volts A/C, THIS is what you're measuring. Be sure to do it on all three stator wires and report back.

      Usually you see about 60v in a stator leg to leg dynamic AC test.

      This Youtube is pretty good for showing the tests & the settings to use on your meter.... https://youtu.be/qqSZWaWEe3s?si=ewkO7CgWWQRl41EW

          Ok
          Can someone tell me what 0.5 means on my multimeter ? That is the question!
          I simply don't know what it means ?

          Is it 0.5v ? I simply don't know and no instructions.

          As for.the analysis you need I'd read my other thread !!! I have done that and it checks ok !!!! My stator checks ok bar this one test !!!! As described above by a reputable company !!!!

          The other thread is discussion on stators.

          This is.ourely asking what does 0.5 mean ?
          0.5 / 5 / 50 / 500 ? What unit is it ?

          If it is 0.5 I have found the issue and this new stator (a cheap one) is faulty and I can get it replaced

            This is the test !!!!
            Below ,50v AC stator no good !!!!!

            This is the only test that fails from all the others that have been ok !!!

            The bike won't charge so surely it's this.
            Question is what is 0.5 at AC setting on my multimeter

              You had the right range selected and the proper connections made, so if the meter is ok (stick it in the mains to test it, but be careful), your stator is highly suspect.
              Mains test - select the 600V AC range and put the probes into a switched socket outlet. Flick the switch on and observe the meter.
              Now you know the 600V range is working, re-test the stator on the 600V range. It will still give a good enough reading to be of use.

                I can't be trusted to go near the mains.
                If i can find thick rubber gloves ..... I may try it but seriously it is clear I am the worst at electrics and can't be trusted with the mains .....

                I have to assume the reading 0.5v means 0.5 volts on the 200 AC setting. Not 5, not 50 not 500 or 0.05v 0.005v. I just don't understand the units.
                I am not really asking the meaning of this simply what the hell the units are ,?

                I have asked m&p for a replacement due to this test result. It is a clear fail. Although other bench tests pass on this new one and class it as ok.

                I must have been unlucky and my cheap reg is a faulty one . (I recall my Stihl strimmer failed. Couod not fix it for over a year using cheap Chinese eBay carb parts. The second I bought genuine Stihl carb - burst into life )

                I usually do what said on here but I know I will kill myself if I go near the mains ......

                  Put you meter on continuity with the audible beep on. Check your leads to each other to ensure they are good. And maybe put a fresh battery in that meter.

                    To answer your specific question, your meter is reading 0.5 volts AC.

                    I suggest you go here to test your stator:

                      Thank you !! My stator (a new one I ordered and fitted ) is thus dead - thanks.

                      I am now back to.my stator thread that has every way to test a stator anyone desires if they read.

                      I now realise bench testing most certainly is not a sure way of confirming one is working. It points to it working only .

                      Anyway cheers - replacement ordered to swap out
