    A note to old forum members...
    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...

  • Returning Visitors

    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.

AC Generator Operation

On my '81 GS650G, does the AC generator begin charging the battery at 5000rpms? I'm asking because I'm still working on the carbs and can't get the bike to rev beyond 4000rpms and, at 4000rpms, I'm only getting 13 volts at the battery.

Thanks!
 
Basscliff provided you with his megawelcome in your first thread from three days ago. http://www.thegsresources.com/_forum/showthread.php?t=209896
If you go back and look, you will find a wealth of information, including how to check the charging system. There are literally hundreds of threads here in the archives on this same subject too. All the information is there just waiting for you to use.

Basscliff says the stator kicks in at 4000rpms but my service manual says to make the reading at 5000rpms, unfortunately I can't get the bike up to 5000rpms.

No; it begins at 1500-2000 RPM depending upon your load and how much power your stator will generate at that RPM.

wasn't referring to you bro ... just the resident 'no-one should be able to learn from someone else's questions' guy.
But as usual, Posplayr rises above that crap.

The Stator Papers, as linked in Basscliff's megawelcome, and on the GSR home page, shows how to check the charging system.

The Finding Fault chart says to rev the engine to 2500 rpm and then check voltage - below 13.5 volts is a fail. You don't need to rev to 5000 rpm to find faults like noted here. More details in the Stator Papers.

I don't like to spoon feed. It's sort of like feeding squirrels at the park; if you do it all the time they become dependant. Give a man a fish and they eat for a day. Teach a man to fish...
