Hi Phil,

What year is your bike ?

With the year I am sure we can find the proper wiring diagrams.

Did you change anything lately that touches the electrical circuit ?

Maybe you accidentally disconnected a lead somewhere ?

Do you own a digital multimeter? Need a quick tutorial on how to use it in concert with the wiring diagram? Step 1 is to verify the silly stuff, make sure all the connectors are connected, fully, in good shape and nothing is brown or crispy. Then check for continuity on each leg of those wires from each end to end. Then (with the key ON) you need to probe the blue (from memory) wire backwards from the headlight socket toward the battery till you find where it's live, and you will have isolated the break or problem. Are you CERTAIN both the high and low beams are testing properly? You're not being fooled by a working high beam, and a dead low beam?

P.S. It's probably a good idea to have the rotary killswitch OFF while you do this or you may kill your battery and overheat your coils.
