I connected a nippy normans usb charger into the canbus under the LHS fairing a year or so ago. It blew the fuse a few months in so I replced said fuse (fuse no.6 that also runs the numberplate light). It's not working again, but the fuse is not the problem. I've tried disconnecting the NN from the canbus but no luck. Do we think the NN has f*cked the circuit?
