Just spent a week in hospital draining their supplies of blood, got out and found a z800 exhaust on the drive, thankyou to my wife Debbie.
It's a 2013 with 1100 miles on it. I did have a pogo bug racer years ago and this is leagues ahead, proper powerful ktm-ish engine.
Did 50 miles yesterday in and out of the countryside down leafy dusty lanes.
I got within a mile of home and it just cut out, luckily the house I broke down outside belonged to a nice guy who towed me home. 
I found the main fuse from the live terminal of the battery had blown. Replaced it and it starts and idles nicely. Only problem I have is 2 red wires that look like they should be connected to something,  charging is ok at 14.47v. I'll attach a few photos incase anyone has come across this before.
Cheers guys.

The very first ones..of the 800s...which I believe was actually model-year 2014 not 13, had in-line glass fuses like that...except they were in a case. They were all replaced with 20 amp sward type in water resistant holders so..get rid of that mess asap. There were only three connections to the positive side, two were cables-one of those went to the starter solenoid the other went to the winch controller. The other small like #10g was system power and possibly the charging circuit if separate.   

hi, thanks for the info, the glass fuse is going to be replaced with a waterproof spade fuse connector.
im just a bit concerned as to where the thick red positive cable connects

One "cable" goes to the winch controller and one goes to the starter solenoid. Both start at the battery positive terminal.

Cheers for the heads up,  managed to find that out eventually with a voltmeter and some luck.
