    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.

Gs850 charging system

Hi I was checking the bike for charging just by putting a meter across the battery poles (it is a good battery) on tick over I am getting a reading 14.1v at 1050 Rpm any significant rise in rpm from there gives a reading of 13.6 v is this a sign of a failing regulator or stator?
thanks.
 
Are your tests with lights off? The Quick Test (see my signature) suggests 6 measurements which all have the lights on.

Since you are across the pond, and the voltage at low idle is so high, I'll swag a guess despite your incomplete measurements.
You have bad connections between battery and R/R ; proceed to Revised Phase A tests (see GS Charging Health in my signature)and measure the voltage drops at 5K RPM clean and repair as required to drive those voltages to below 0.2V (or better)..
 
Hi thank you for the quick reply, yes I tested with the lights off I will proceed as you suggest and let you know the results ASAP
