Headlight problems

I have a 2001 Vulcan 750. I was on a ride with a buddy yesterday when the LED volt meter that a previous owner had installed went red. So I pulled off to figure what was wrong. While doing this, my headlight just went out. Everything else works, aside from the voltage meter which is still blinking red at me. We road another 30 miles and bike runs fine. I can not get the headlight to come back on. The filaments appear fine, no fuses blown, neither high nor low beams work. Any ideas? The local dealer is telling me three weeks just to look at it. I would really rather avoid that. Thanks for any help

Trace the wires from the digital meter and see if they are spliced to the headlight. Possibly that splice is bad, interupting power to both circuits.

Actually, surprisingly, it was the blue wire coming out of the fuse box to the reserve light unit. For what ever reason the blue wire was not getting power, killing the whole circuit for the light. There was an empty slot beside the blue wire slot, so I just swapped them and now everything works aside from the stupid voltage meter. Any ideas on a wiring diagram for the fuse box so that I can make sure that empty slot is acceptable? I think I may need to clean and align the contact points in the fuse box.

What you did was what some people do when their headlight goes out. It is in the threads in the forum, under headlight problems. Usually the relay for the headlight goes out in the fuse box. If you down loaded the manual for this web sight you can look at the wiring diagram for the fuse box and see the relay that the blue wire goes to. By switching the wire how you did is the quick fix, but the headlight comes on now as you try are trying to start the bike.

I had the same issue with my headlight and made the same "fix". The headlight does turn on when the key is in the ON position. I've had mine like this and haven't had any issues. Kept a close eye on the battery and its been okay as well. Long as you have a good battery, there should be any issues. But I guess that's the case most of the time with our bikes. The only other thing that can be done is to buy another fuse box. I think someone on here is selling one but can't remember who. Check in the sell or swap forum.

Cindy has a a Fuse box aka Junction Box or better known as the JB... but that isn't the only solution, you can also repair your own JB.

Alas, 'tis sold. But also keep an eye out on eBay - http://shop.ebay.com/?_from=R40&_trk...All-Categories

Although they're from '86, there are two on there now.

so i have also been having the same problem so i cracked and went to the Kaw dealership and ordered a new Junction box/fuse box,,, hooked everything up and guess what? still having the headlight issue,,, so i hope that doesnt happen for you too. im still trying to locate the headlight issue as i think it has something to do with my charging issue i have been trying to locate for 3 years now. dont want to take it into the dealership to find the elctrical problem because the dealership here said it would cost me around 350.00 - 450.00 JUST TO LOCATE THE PROBLEM NOT FIX IT. unfortunatly thats the only dealership close to me,,, so 3 years later i cant ride my bike to far or for long rides until i figure out the charging problem. yay me
