I need wiring schematics for a 2001 kawasaki vulcan 1500 classic...keep blowing tail light fuse.

Check earth is good

sounds like a dead short from battery to ground follow your tail light wires all the way back and check for bare or overheated wires

TO ALL VN1500 OWNERS....This once happen to me,
I went to the garage to start the bike "Nothing ""The first thing is the lights are bright but no turning over,Next you think the solenoid is kaput but the answer was very simple and the fix takes 30 seconds..
Do not take the bike to bits looking for other problems and look at the clutch leaver and you will see some wires going into a plastic shroud going into the switch in the clutch leaver, Make sure this has not popped out if its connection as it some times may do after a few years due to constant turning on the handlebars,
When this is not connected you will have a bike that will not fire up but comes alive and you will hear a clicking noise but this is from the engine carb area and every function of the bike will work but it will not turn over, Worth looking at and saves sixteen quid for a starter unit you never needed.

You might want to trace the wires and see if you have any bare wires that could be vibrating around and shorting out as you ride, they would be moving unless you where riding

you have a short somewhere in the ignition line. check all connections at coil, check for worn spark plug cables grounding on block.

well i would try the switch and see and if that doesnt work then check the wiring for a loose connection or ground or maybe it could be as ez as checking the light bulb it might be loose in the socket

From another forum,

"You've got an exposed hot wire somewhere in the power circuit that's grounding out and causing resistance in the wire. Not sure how to help on this one, electrical problems are damn near invisible, but I'd start looking for a burn mark or scorched insulation on any of the wiring leading up the relay, starter, or main fuze block in the tail."

Brother you got a dead short was salvage do to wreck if so check inside head light bezel for split or frade wires.
