Decided to take another look before trying to get the bike to a dealers.
Took each fuse out again and found a 15amp hidden behind the loom that I must have missed (sunday morning, bike won't start, annoyed look
).
Nicked fuse from car and up all the clocks spring into life
Turn the lights on and the fuse blows again
Caught a glance at rear light wiring and spot an earth wire shorted to the live wire. Bit of insulation tape and way we go again.
Now a happy bunny again and looking forward to next weekends rideout
