Lighting problem / Electrics expert required!

You jumped the gun buying the switch until we were finished diagnosing. Removing the switch and checking it was always what should be done before buying anything, however I thought you you said in a previous post that you had power from the fuse.
The good news is that I need a right side switch for a Fazer with a broken kill switch (he dropped a piece of wood on it and broke the red part that you press on the switch) and will happily take it off your hands. PM me with the cost

Had to run a wire on a bandit yesterday with a similar issue to supply the light power, would have preferred to find the break but he was going on holidays for 2 weeks and will have to wait until he returns.

As the brown runs backwards and forwards on the loom the problem is probably close to the fuse. You could try lifting the fuse holder and checking it or see if the wire pulls off the back of the fuse holder. You should be able to see it and/or get at it from the right side. Running a wire should be a temporary option as finding the issue is the safest option.

I ran a wire from the Signalling fuse to the brown in the block that joins to the lighting connector as a temp measure and everything works. I may well look into finding the fault in the loom but for now its just nice to have everything working again.
PM me your address details and you can have the other switch for free as a thanks for all the help you have been on this.
