Put a new battery on the Silk and thought I'd just check the charging voltage at the battery.  It was jumping all over the place, going up to 20 volts.  Thought I had a zener diode problem or a bad earth .  Checked all the connections and continuity of the earths and nothing wrong.  Clipped the meter onto the zener terminal and alls well.  Turned out the digital multimeter and leads were picking up interference from the ignition system.  Moved the meter away from the battery area and all ok.  Only gave me an hour and a half of head scratching!  At least I know the earth points on the bike are all good now!
