G650x Fuse blowing
 
My G650x-Challenge keeps blowing fuses (F) when starting hot.
New battery, all terminals and connections checked and cleaned, Starter relay and starter switch swapped from another XC with the same results.
Any ideas much appreciateddoh

Unless you want to trace the wiring loom and find where its shorting out (i am guessing a wire is earthing somewhere) then you have to take it to a bike electrician and get him to find where.

Shortcut could also be in the ignition lock.
Not so easy to borrow this from your friends bike, but worth a try.
Works only if there is no immobilizer in the locks!

An old trick is to connect a bulb instead of the fuse to the fuse-socket(T-connection).
The job for the bulb is to limit the electric power, so you can start your bike.
You are now able to check the cables (pressing, bending....), when your fingers find the fault, the bulb changes its brightness.
Darker means cable is ok now, brighter means shortcut.

Be carefull, bulb will get HOT

Good luck

This happened on mine after I added some bits, I forget what. It seemed to blow the headlight fuse every time I braked. My rear pads were low which confused the hell out of me how that could be related.
In the end it turned out to be the wiring loom running down the left side of the headstock into the frame. I must have pulled or trapped something and the wire had bared against the frame so every time I turned hard left (pulling in to park, etc) I was popping a fuse. It may be something as simple as that so if you've done any work check there first and look for all the obvious things, broken or frayed wires touching.
It was a daunting task for me and a hell of a relief when I found that was all it was.
F is diagnostic plug, starter relay and indicators, right? Have you checked you're using the right value fuse? I think that was the same one that went on mine. I thought it might be my brakes but that was a red herring. I can't imagine why a fuse would blow when starting hot though.
I hope your is just as easy. Good luck.
