Hey Guys,
The headlight on my Vulcan is out. I suspect is the common problem with the starter relay. I've decided to overide the relay, and hardwire it with juice from the iginition. As per my wiring diagram, the brown wire out of the ignition is hot only in the "on" position, and not in "off" or "park" Ive elected to use this wire as my power feed, on a 10 amp fuse in between.

Now the question. Which wire to I feed into to provide the power after the relay. The relay has three wires attached. If I am not mistaken, the white is the hot wire out of the fuse, and the yellow red is the wire that is given voltage when the relay kicks. So in theory, feeding the yellow red wire from the brown ignition only across a 10a fuse, should provide a key on headlight. This should all be before the high/low switch, enabling the light to function normally without the starter relay delay.

Anyone have any comments? Good idea? Bad idea? Will work/wont work etc?

Thanks for the help guys

UPDATE 05/11/2007

-Just reference for anyone else:

With a little help from KEBO, I decided to jump the Br (brown) wire (ignition only) over a 10A fuse to the L/O (blue/orange) headlight primary wire. Put it over a multimeter and all seems ready to rock and roll. Headlight on with key in ignition position only, off in park and off. Highs/lows work fine, high indicator working fine. All other electrics in working order.

I scanned the wiring diagrams from my Clymer's manual, so if anyone needs the wiring diagram for any 1987-1999 VN1500 (any sub series) just let me know and i'll email it to you. Just let me know what model exactly.

Thanks for the help KEBO, colors were the same from mine to yours.

KEBO, I would really appreciate a copy of that diagram for a 92 Vulcan 88 1500. I am having similar headlight problems due to a previous owner's amateur wiring attempts.
Thanks for the help,

I would have to say that if it had a relay in the circuit then one should stay in there. Typicaly realays are in the to "trigger" the circuit so to speak. So you dont have to use heavey wireing all thru the circuit. Smaller wires are used to turn it on and then only large wires to carry juice. If you use the smaller wires for carraying the jucie without a relay than the circuit could be over loaded and melt wires.

Headlight Problem Vulcan 1500
While riding, I changed my headlight to high beam, to notify another driver it was clear to move over, then back to low beam, shortly there after i noticed that my headlight was not working. Pulled bulb, looks fine, changed bulb still not working, not finding any extra fuse in the wiring line to headlight. Any ideas, switch went bad or headlight portion of main fuse?

Until one of the more knowledgeable guys chimes in..... I would check for power at the headlight. If no power,
there may be a relay in the junction box that could be defective or something.
Also, I would install a new fuse as a just in case --- you never know sometimes. :)

The headlamp went out on my 2004 Vulcan Classic 1500, and the battery is discharging when it's running. I'm thinking alternator ...... any suggestions?

Probably the right place to start looking. Charging system. Could be a rectifier or a stator. I know the 900's had poor results for the 07 model I had with the stator burning up around 20k or so. There should be threads around on how to troubleshoot the charging system. How old is the battery? Charge it up first and see if it will hold a charge. No sense overlooking the obvious first. charge it up and have it load tested at autozone or advanced.
