    Right I'll update with a full analysis bit
    I attach pic of my original thought good on
    left and suspect 0ne on right that looks cooked !
    blackened , hot smell ... (as I'm changing oil
    and filter too and had to warm bike up).

    Never really seen in the flesh a cooked one
    but as you say it is clear when you do and compare
    to a known working one

      Neither of those stators look good..even if left one works now, you’ll be replacing it soon...especially if you stick with a shunt r/r

        ANALYSIS:

        With known to work old (very old
        poss original) stator with increased
        revs it increases voltage correctly.
        and
        new regulator.... came from uk company
        but know nothing of it bar that it has no sense wire.

        So I am back on the road.

        test 1 on new stator: engine off.
        200 ohms on MM
        leg to leg
        a - b 23
        a - c 23
        b - c 20

        test 2
        each stator leg to earth on battery at 200 ohms
        on MM
        a - 1
        B - 1
        c - 1

        So that is the difference if res isn't 1
        then it ain't gonna work ?
        knackered one showed 5.7 ohms

        test 3 - didnt do as it clearly works

        (also 320 miles after running in oil change
        and filter done)

        - anyone be intersted in the test 3 on each leg
        with increased revs ? to see difference
        from working to knackered one ?

        - if anyone is on the ball ... how much a stator cost ?
        I wont know till tonight and you lot
        ain't covered in oil as I am.

          - Test with engine running, stator wires disconnected from regulator ,
          MM set for 200 ACV

          test stator leg to leg,
          in 3 separate pairs

          2k revs
          a-b 20
          a-c 18
          b-c 24

          3k revs
          a-b 28
          a-c 25
          b-c 41

          4k
          a-b 28
          a-c 25
          b-c 41

          5k
          a-b 30
          a-c 30
          a-b 47
          These are poor results. All three "legs" should be very near the same and also, voltages are all low ESPECIALLY if the stator is an original to the Suzuki, the which, in particular should read very near 70-80vac. Other makes of stator may read slightly lower.

          That said, given a working regulator, and good magnets on the rotor, this stator may still supply some little bit of "charge" but not enough to run the ignition,headlight,brake light,turn signal and as well replace the battery charge lost to starting the engine...

            I bought this Electrosport stator from Amazon for $80. Not sure about Ł conversion. It was much cheaper than direct from ES. Amazon said it wouldn’t fit my bike. ES confirmed it would. And it did. No idea if this one would work on your bike, but check fitment for yours on electrosport.com

              Just de oiled my hands and searched for prices on here in uk.
              About the same price as yours for a standard one - an Electrex - 66Ł
              So not so bad. Do i need one for 150Ł - not really as that last one lasted 65,000 miles.

              @Gorminder - They are poor as you say - i will post the stats for
              the new working one (off my old engine) as im interested what the stats are when its working.
              The stats posted (in your post) are of the knackered stator that can run the bike but the battery will be discharged
              needing a bump start always. It also seemed to start blowing fuses.

              The stator from my old engine works a treat but i am ready now
              to buy a new one .....
              p.s someone said my stator not great and not good if i use a "shunt" RR ? Whats shunt or do you mean Sh*t" ? lost in translation .....

                you need to read the write up I posted before

                the evidence is settled.....a series unit is the way to go

                  UKJules, have you done any of the searching on this forum as I suggested or even bothered to click on the link that Tom203 posted on here showing you the differences? How about doing some of the work yourself instead of expecting everyone to spoon feed you the information. There is no loss in translation here - it is SHUNT and SERIES - SERIES is better for your electrical system than the SHUNT style. Go do some research

                        ukjules, you are out of line old kiddie. The problems you are having are common and the fixes well known. Knowledgeable people are willing to help but you're off on your own path... good luck. Do yourself a favour and spend a couple of weeks reading about your bike on the forum, this is the way.

                          Talk about an ungrateful piece of....just because you're told to do some work you want to treat some of us like that? Fine. You have fun trying to fix stuff you clearly don't understand or want to unless someone tells you the answers. I feel sorry for you

                            Cowboy you havnt helped me at all ! Not in any way.
                            All you can do is bat off questions in an ignorant rude way.
                            I told you not to post but you cant help yourself.

                            You're no biker buddy ! You are a troll and I consider
                            people like you vermin. You're a sorry state.

                              UKJules, you speak to people like that on here and nobody is going to bother helping you out anymore.

                              Dont think that your "analysis" will be helping out anybody because, as mentioned before, there are countless threads on this forum relating to the issues you are encountering, and they have already been explained, analized, and rectified by people with a lot more knowledge, experience and manners than you have.

                              Good luck sorting out your issues on your own.
