Does the highbeam work?
Are they plugged in ( :D )?
Anything else not working?
You're certain the bulbs just aren't burnt out?

There is an interrupt switch that cuts power to the headlights when you thumb the start button. I know nothing about it, but I'd probably start with researching that if none of the obvious checks pan out.

Everything else is working, highbeams don't come on either and I can't hear the relay clicking. They were working fine before. I'll check the fuses. The only fuse block is next to the coolant overflow correct?

none of the fuses looked blown, the 20a headlight fuse looked fine, didnt see any bare wires at the front harness. i'm puzzeled. they worked just fine when i took the fairings off.

if i hook a multimeter up to the headlight harness with the ignition on, shouldnt it read 12 volts?

You should just check the fuses with your multimeter set on ohms / resistance Ω. Resistance should be at or really close to zero. You can make sure your meter is on the correct setting by touching the probes together and seeing a zero or close-to-zero reading. Sorry if you already knew all this.

I need ideas here fellas. I put new fuses in, the battery is good and not even 6 months old. Wires look fine, what else could it be? The bike starts and runs fine and all other lights work.

???

You need 12v and ground at the lights, you might have lost the ground, you can put the meter on d.c. volts and check across the headlight connector, if no 12v check both sides with black lead to negative on battery. sorry don't have wiring handy for colors. you have wiring/manual? trace backwards to fuse for power, and inspect that kluge of connectors under sidepanel. And headlights should read 0 or close to zero ohms across the terminals. Hate to say it but closely inspect everything you might have touched

ok, so both bulbs are fine (hooked them up directly to the batt) i have 12v at the 20a headlight fuse slot, i have 12v at the black and red wire of the highbeam relay connector, i swapped a known good relay to the highbeam connector (fuel pump relay) and the lights still wouldnt come on, both headlight harnesses indicate proper ground.

i'm not getting 12v at the headlight harnessess

don't have wiring in front of me, don't think the lo beam goes thru relay- the start/stop switch hi relay for hi beam. check all the wiring/handlebar connector switches and interconnects? display work right?hi beam indicator?relay have ground? Ill bet you smack yourself when you get it

Good thing I have my old man around. Spent a hour troubleshooting a 1 second problem. Worked the starter switch for a bit and viola. Guess the starter button was slightly seized

Might want to take that apart and dob some dielectric grease to protect and lube that area. Glad you found it.

If you see and corrosion in there, clean it first with a good electronic cleaner or rubbing alcohol with a swab, then apply the dielectric grease.:cool:
