I didn't know the Vulcan ever had them. I'm sure glad mine doesn't. If it had, they would have been redesigned right away. I had a Yamaha Virago 750 that had them and what a nightmare. Either they would turn off before you got to the turn, or they would keep flashing long after you made the turn. I finally rigged them so they worked as normal turn signals. Jerry.

I am a motorcyclist, NOT a biker.

Slim, IIRC you can take one of those blue wires and pull it off a connector and plug it onto an empty connector next to it that is powered when ever the key is on. It can get your lights back on quickly to get you back home in the dark. Sorry, I just don`t remember the specific wire or connector.

I am sure you know this and can spell out the particular wire and connector location to try this solution.

yes you just move the blue wire into the empty slot... doesn't matter which one, they both o to the headlight eventually. but then you bypass the relay and can cook the wire harness if something should fail...hmm wonder how I know this one...

Bypassing the HL relay will not possibly "fry" your harness since it is still a fused circuit. The only difference is the HL will come on as soon as you turn your key.

If you decide to alter your wire harness for aftermarket electrical devices and don't do your haome work then 'YES" you can fry the harness. It's usually something stipid like one copper strand hits a ground or you use a fuse that's larger than the "load" the system was designed for.

well my harness is shot... and the only thing i did to it was add an aftermarket headlight, and bypass the relay... to wire in the new headlight, i ran a wire streight from the spare slot on the JB to the headlight, and grounded the headlight out through the OEM ground wire.

Hey slim. I moved the blue wire on the JB to the empty slot when I got my bike last year. Previous owner put a switch on there but then the highbeams would not work. When I moved the blue wire to the empty slot, headlights worked fine. As Lance said, the only difference I can see if that the headlights turn on when the key is in the on position. I just keep my battery charged well and she cranks up every time without issues.

So i went out and bought a new (to me at least) junction box thinking that this is the problem and I installed it today. The headlight is still not working so I am thinking that it must be the reserve headlight unit. With the new junction box all the lights work, blinkers blink but the headlight is still not working. The lights on the dash do not show up for the headlight and when I flip the high beams on that light does not come on as well. Would this be the reserve headlight unit not letting it work or is it something else? I do not own a multi-meter so I am thinking that I might have to go out and buy one to track down this problem. Sorry I am so amateur at this I do like learning about all these things at least.

One other thing, How do you take the wires out of the plastic around them at the junction box? I was hoping I could just switch the blue wire with the empty spot to at least have a headlight till i get this problem sorted out. I have tried pushing the wire out with a flat head but no luck, I am afraid I will bugger up the connection if I mess with it to much.

Get a test light at Wal mart, you can even get a decent Multi Meter for cheap at Wal-Mart. but in order to help you fix your bike, you need to have the proper tools.

Every one needs to own a Test Light at a bare minimum for testing electrical problems. A test light has about a thousand different uses depending upon what you are testing and how you hook it up for testing. A Multimeter is also a good thing to have, but make sure you get a digital one instead of analog. But until you get the right tools, its going to be hard for us to help you figure out what is going on.
