no headlight

I noticed yesterday before work.. my headlight isn't working. My signals and running lights work. I tried to take it apart and look at the bulb and it looks ok, although I couldn't get it completely out. Does the headlight and running lights work off a different fuse? and where is the fuse box on these bikes? any help would be great.

Headlights are triggered off a stator lead.

Fuse box is under the left-hand side cover (or is it right? lol) It's behind a side cover.

If you don't see any fuse issues, you may want to check your charging system. The stator could be going south, but it's too early to make that suggestion.

check the blue wire in the 8 pin connector on the side of the fuse box for power while the bike is running.
if there is no power you have a bad headlight relay which is built into the fuse box and can not be replaced.
a temp fix for that is to pull the blue wire out of the 8 pin connector and push it into the empty slot on the same connector this bypasses the headlight relay and your light will come on as soon as you turn the key on
hope this helps

nope that means it isnt the relay because it is already bypassed check for power at the blue wire where it goes into the fuse box
also0 have you tried turning the high beam on and see if it works if it does then you could just be dealing with a bad bulb

Yeah, I tried the highs. They are out. Another thing... my headlight indicator has never came on.... I didn't pay much attention till now.

I will have to check for power tomorrow, it's dark here and I don't have a garage. Plus my meter is in my car which my sister is using. But I will see what I can do tomorrow...

It will come on and stay on if youve tapped the starter button...makes no sense to me, so if the battery is low, the light will drain it more whilst trying to start...I may put a switch inline to prevent that....stupid design....they couldda made it (fer safety) so's it comes on in all gears besides neutral...

Wolfie does your light come on when you turn your key on? Simple solution... wire the blue wire up to a relay.. some one bypassed he relay inside the JB because it was more than likely defective.
