Vulcan 2000 wont start, any suggestions?

Hi guys this is my First post here,

Today my Vulcan 2000LT VN would not start, no power to gauges etc firstly I assumed the battery was dead, reading on the multi meter was 13.8V but as soon as you switch it to "on" position battery voltage hits zero basically.
To eliminate the battery as a problem we hooked it up without the battery to a running V6 engined car we get power to the dials when ever it is connected to the other battery (with or without motorbike battery) but when you press the button to kick it over it makes a clicking sound (in my opinion it does not sound electrical) it also does not sound like it is coming from the starter motor but does sound like it is coming from behind the main loom just before it goes under the fuel tank.

see Video for sound

Any help would be greatly appreciated
