Only problem I've had with my electrics is poor routing causing split speedo cables and poor earth cable has to be cleaned and prepped after every other ride otherwise bike will short out or not start at all.....

 

Short to ground.

 

I’m 6’2” mate so it’s not an issue!

Haha!! Joking aside... I have no idea what you mean?!?

 

there's often a wire rubbed against the headstock..... on the later bikes there's a protective sticker to stop this happening...

 

Check each and every wire (you can ignore the brown wires as they're earth) that runs along the headstock as others mentioned. If you have a steering damper, the clamp mount on the headstock tends to cause this as the wires rub on it and eventually (not long) shed themselves of the wire jacketing and short out.

 

I've searched through all the wires and can't see anything obvious?

The only thing that did raise suspicion was the horn connectors?

I had taped them up together (from new) and there was a lot of moisture in the connectors. The horn has never been attached.

Could that be causing the issue?

 

Could that be causing the issue?

Yes if the positive wire or its connector touches the frame. Can you turn the fan with your fingers easily?

 

If you can’t find a problem with the wiring. Unplug everything that’s on the same circuit as the 10 amp fuse one by one. As it could be the back light it’s self that’s caput for example.

 

Wire a headlight bulb or h7 in to the fuse holder in place of the fuse,so one wire in each side of where the fuse would be,if the bulb lights up one side is going to earth Shake and pull the loom bit by bit till the bulb goes out, or vice versa

 

It was the fan!

As soon as the bike got hot enough and the fan went to kick in it blew the fuse.

It doesn’t spin freely anymore so I suspect the bearing has packed up. It can’t be stripped either.

Dealers want just over £70 + delivery but found the same one on eBay for £50 posted.

Shouldn’t have to replace as bikes only just over a year old

 

It makes me happy when I shoot a bulls eye at the first try

Good to hear you've sorted it...
