My Speedo and Milometer on my '02 WR426 have stopped working. I think it's a stock piece. The other bits on the clock are working - indicator signal LED and headlamp LED etc.. The clock's also making a buzzing noise when the throttle is open. I've checked that the cable is connected and no problems there, so it may be an electrical problem in the clock itself - in which case I'm clueless as to what to do. Anyone got any ideas??
