 Blowing ignition fuse

Hey Boys.

Ive blown the ignition fuse 2 times. I replaced it, but it blew again after 30 secs or so

It shuts off all lights, the display and Im unable to ude the startbutton. Fuel pump keeps priming, and the bike can be bumbstarted...

I guess its a small short somewhere...?

Any input is much appreciated.

Back from my trip, and Im about to mess with the bike.

More info: The bike doesnt cut out when the fuse blows, but lights and display go out, and as I said, no power to the starter. It bumbstarts fine, and theres no warninglight after replacing the fuse...

After changing the fuse, the bike turned on and idled fine for 10-15 secs, then blew the fuse just as I touched the handlebar. It didnt seem like I touched it enough to wiggle wires, but I guess I'll have to go check now.

It doesnt help to have the lights shut of, so thats not the problem. I kinda knew that as the lights have their own fuses.

Only accessories is heated grips, wired directly to the battery, so they shouldn't give any problems either. They were off the whole time aswell.

I havent checked it it blows fuses with ignition on, but without starting the bike. I dont like the idea of just changing fuses all the time if something is shorting out, but I guess it could be a good way to troubleshoot.

The plan is to meassure battery voltage, but it should be fine as it starts with a new fuse. And check wires behind the headlight.

After that im pretty much screwed Shog I know basic electrical stuff, but my brian shuts off when i see a wiring diagram.

The wires for the licenseplate-light got between the seat and the frame, so I hope that was the cause of all my trouble.

I insulated the wires and changed the fuse, all is good.

But I dont like how so much sruff is on one curcuit, it seems stupid that you loose the startermotor/ignition, because of a short in the rear of the harness regarding the lights...
