In my 2010 touring manual the power goes from the ignition switch to the 15 amp fuse. From the fuse the power goes to the right turn switch, the DLC and to the tsm/tssm/hfsm and to the abs. For the fuse to burn out, the power to ground has to be downstream of the fuse. I have no idea what the DLC or the TSM are. I also don't understand why the drawing shows power going to the right turn switch(why not the left turn switch also).
DLC is data link connector
TSM is turn signal module
DLC is data link connector
TSM is turn signal module

Ok, here we go. I will try and describe how to locate your problem. This is not an easy description but try and follow me. In order for a 15 amp fuse to blow you have a " short to ground". In simple terms a wire from your your 15 amp ignition fuse has most likely rubbed against something enough to bare a wire. I dont have a wiring diagram for your bike so you will have to do your best to locate the routing of the wires pertaining to the fused side of this wire. The best description I can give you is ; the ignition fuse
is fed from the battery then the appiances are fed from the fuse. The problem will be between the fuse and what ever else is on that circuit.
What I do is fabricate a test unit. Get a KNOWN working headlight from a car/bike or a horn would work well. Connect 2 wires to this item with spade connectors similar to the blades on your 15 amp fuse that blows.
Remove the fuse in question-in this case your 15amp ignition fuse.
Plug these 2 wires from your test unit into the 2 terminals were the fuse was. Be critical that they are not shorting together at the fuse block.
Manipulate the wiring, shove it around,flex it, be somewhat aggressive.
If you see the light activate or the horn go off, you have issolated the problem area.
The idea is this test unit gives you a visual or audio signal as to when the short is located while "working the harness".
Often these conditions occur after some type of repair,maintanence,upgrade on your bike.
I hope this helps, electrical is always a chalange. Get back to me if you have questions.

Thanks to everyone for all for the input. Somewhere in all of this has to be the answer. Will post the results shortly.
