    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

SH 775 R/R test

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

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.

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.

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/showthread.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.
