    I'd like to know what clamp tom is using and it's accuracy tolerances. You know just to verify whether his stator could possbly test different than yours or his clamp/meter indeed lacks in accuracy in the amount you indicate.

    Just cuse, I like to be through and analytical when there's time to waste
    Perhaps you missed the point that, when expected and with completely different stators and R/R's, Tom's 120 hz reading matched my measurements that I took close to 3 years ago. I don't think that is chance.

    Further, his 400 hz measurements are all explainable, again not chance.

    I'm not wondering why you think there is further data required on the setups; It is all explainable

      He copied from you

      And the scientist turns religious, it's all an act of god. I'm also glad to see you spread the word of the SH-775's coming as the chosen one as well.

        As stated in my first post, no idea on accuracy claims on anyhing above 60 Hz. No manual- got meter off friend whose shop I wired- "UTI" is brand
        Unusual thing about this meter compared to most clampons is it has low scale ranges ; up to 2 amp, up to 20 amp and up to 200 amp. Checks out good on my 60 Hz stuff.
        I was looking for a comparison reading between the two R/R's - the meter error should be the same on both at 400 Hz.

          Thanks tom203 and posplayr. You have confirmed my decision to use the SH-775 should I have the opportunity to do so. I really appreciate your efforts to help out the community. Ray

            Nice to see some confirmation.

            Prices seem to be holding fairly stable at most of the Polaris parts retailers.

                How are the current model bikes handling their charging duties? For instance, is my 2009 FZ1 using a shunt system or series?

                  I did that calculation; you seem to be at 75% of actual at 400 hz

                    Neither.

                    Fortunately for us, modern bikes (most that I know of) put an alternator behind the cylinders -- to keep the engine narrower, for one thing. An alternator's output is controlled by simply adjusting the current through its field windings, so the magnetic field's strength is the variable. On our older bikes, that's fixed.
                    and God said, "Let there be air compressors!"

                      There are still alot of modern bikes that don't have alternators and that suffer even worse charging problems because EFI requires a high current draw fuel pump and so the total power requirements can approach 40 amps.

                      These guys problems could not even be fixed with a SERIES R/R they also had to resort to using an oil sprayer in combination with Series R/R.

                          There's some commonality between that thread about Buell charging issues, and this one in our own Discussion area http://www.thegsresources.com/_forum...d.php?t=210184

                          For the Buells, there's guys with newer bikes that are supposed to be top-notch...yet have the same charging and electrical issues that we have on our 30 year old machines, or maybe even worse.

                          Newer isn't always better!

                            Thanks for doing the test. I switched from a shindengen shunt right at the discovery of the sh775 so it's nice to have some confirmation. I've had no probs with mine.
