    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.

Was given this advice around 30 years ago

Just thought I would air some advice I was given when I got my GS 850 and maybe start a conversation an old mechanic told me to always keep a good battery on the bike, and always turn on the lights when it was ticking over and not at high revs he believed this put less strain on the charging system and preserved the stator and regulator.
i did follow the advice just finished the install of new stator and 775 so the original parts lasted 40,000 miles and still charged at a max of 13.8 v luck or was the advice good ?
 
Hard to "turn on the lights at high reves" on any of my bikes since the lights are on all the time. The problem with most issues related to the charging systems on our bikes is more corrosion of connectors and low current draw (no headlight on) since the R/R is a shunt type regulator. The 775 series regulator will fix that.

I think most of that advice was from the Shunt R/R era. It also sounds backwards as you want loads ON when charging the most with SHUNT R/Rs. If teh loads are lower teh higher teh stress on the R/R and stator from the power/current shunting( dumping) away from the electrical systems.

As mentioned with the Series SH775 you the advice can be disregarded.

Hi yes it was from the shunt era I realise that the series rectifier solves the issues and thanks for the help and information you have given me and others.
 
On the early bikes, turning off the headlight turns off 1/3 of the stator's coils, maybe this is what he was talking about.

I haven't had any electrical failures yet, in about a half million miles on a whole bunch of different size GSes, although I have rescued a lot of them with bad charging systems. Every single one had corroded and burnt connectors as the cause of it all. Clean it all up, replace the failed parts if there are any, good to go another ten years or so.

If people would have done that thirty years ago almost none of them would have failed.
