    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...

Bike dies when headlight is on...

Took bike out for a ride and noticed the headlight dim. Bike eventually died on me. Turned everything off on the bike and kick started it, it runs fine.. As soon as I turn on headlight it dies. Any ideas on what usually causes this, keeping in mind I just bought new battery and it was fully charged. Not sure where to start from stator? regulator? rectifier? not so sure how to properly troubleshoot
 
Thank you for pointing in right direction. Will take a good read and post progress.
 
No worries. Just a side note, it really helps when you have your bike in your signature, just makes the answers go a little smoother. Glad to see another GS on the road.
 
What bike are we talking about?

Actually, it doesn't make much difference (this time around), but some bikes have specific problems that are not found in others.

Even though the battery was "fully charged", how long was it before you noticed the dim light and the dying? If it was more than half an hour or so, it's quite possible that your bike is not charging at all and the battery is simply DEAD now.

A few minutes with a multimeter and this guide will tell you where your problem lies.

It is a 1978 Suzuki GS 750 (nd) ignition / I read through the info and took my new multi meter, and literally checked everything from grounds to proper volts. Turned out to be a connector, one of those clip on connectors :mad: chopped it out and soldered my connections. So far no issues while driving at night with headlight on:D. I appreciate the info. on the electrical end of this bike. Those links are like a trouble shooting bible. On a side note I got her up and running nice, absolutely love this old bike.
 
Finally got a couple pics up as well, any pointers on how to dress her up, I wanna hear'em
