to help themselves. I asked if you had a wiring diagram/haynes in which you never responded. If you don't have one...just say so.
Wires are color coded and with this type of snag we are more able to help you with a diagram as we can't see your loom...but we can

Did you check the right circuit on the fuse box? Headlite is the 'B' circuit and you should see a 20 amp fuse with 12 volts (green/white wire)
Your model came with headlight relays from what I can see and without them or not even knowing what model of loom you have you will
have to physically trace the wires and check for continuity and voltage as req'd. Or....start over and install a new syatem as BobA suggested.
I'll say it again...a manual is good to have for basic stuff on this bike. It also clearly tells you how to take the gas tank off. I suggest you get one. I'm
