Found it. Noticed the kill switch was receiving power and sending it,but the plug where it connects to the loom was not getting the returning signal,then as I checked the the plug and moved the wires it fixed it's self........temporarily!
Turns out it looks like the switch loom looks like it has at some time got struck by the bikes lock stop and squashed,virtually severing the returning power wire and damaging the rest.
