Re: New cbr 929 help please
With any electrical problems I always check the fuse box first to see if any fuses are blown.
Then look at the area that is having problems (remove the blinker, speedo, and look at the connections to the headlight)
If everything there is intact there then check to see if the device is getting power by using a voltmeter.
If it's getting power, but not working, you fix the ground wire... If you're not getting power than move on to looking at the switch... in this case look at the left hand control, take the two screws out of it and look inside to see if all the contacts are intact and functioning. As for the speedo, I think the 929 speed is detected off wires going to the transmission near the front sprocket (look in your manual either way).
If all that looks good than you'll have to follow the wires in the wire harness from all the non-functioning electronics... it's a bitch of a job... but you'll have to remove the tank, seat, front subframe brace, and take off the protective black tape surrounding the wire harness to inspect the wires.
A short or even a cut in the wire can damage the wire in that area... mice can sometimes chew a hole through wires and cause these problems.
