    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.

GSX 400 E 1981 not charging the battery

Hey ! I`ve asked this question before, but I want to know if there is anybody may have the knowledge to put me in the right direction.

"check all of your contacts?" , gees, doesn`t anybody know where it`s most likely for the problem to be ? :)

It doesn`t charge the battery, elsewise everythings fine. Since the battery isn`t charged, the head light seems to be a little blurry at low rpm, but that`s because of the battery I guess.

Also, after reading the stator papers, if that battery is more than a year old, yank it for a new one. Trust me, it makes a difference :twisted:
 
Hey again!

I got the bike last summer, and I replaced the battery.
Ofcourse I forgot to remove the battery when I put it in for winter storage, but I will go and get it in this week. The battery was flat when I putted the bike "inside".. .


There has to be some kind of fault with the battery charging , since I have all the normal lights when the engine is running.

Re: GSX 400 E 1981 not charging the battery

There are aproximately 40 junctions in your wiring harness. If each connector/junction/ground is dirty and loses even 1/10 of a volt, that alone would drag your system voltage down by 4 volts and you charging system would not charge the battery and everything would appear to be working normally. So, it isnt always as simple as "most likely". The only sure way is to check and clean all connections and check voltage levels at each relative to battery voltage to see why kind of system drop you have. Then check stator output and go on to the R/R. Be sure and check grounds as well.

The connections to check are the three wires coming from the stator and the wires coming from the R/R and check all of the ground wires. I also sugest adding an extra ground wire from one of the R/R mounting bolts to the (-) terminal of the battery with 10 ga wire. A bad ground will cause a high resistance resulting in a loss of voltage
