Could be a earthwire that is connected to the shielding. Could be why it is only 3" long.

I think that the coil has outside a graphite layer. So if the wire is connected to gnd then it is the shielding wire of the coil. If nothing is connected to the wire, then i don't know

I did not see any wire same with it when i opened my Tornado 10" coil.
Maybe Carl or Reg knows the answer!!!!

Is the plastic case made from conductive plastic, like that used for electronic component anti-static boxes? A simple multimeter test should confirm this. You wont always notice if such shielding is missing, until you try it in difficult conditions, such as long wet grass, when it could false-trigger excessively. Regards.
