Second Earth Wire

smaller second earth wire ,where does it fit?
my 2013 America seems to be dead , only thing that happens when I switch the ignition on is the oil pressure and the neutral light comes on,everything else is dead,.can anyone help please,has a new battery which has been on trickle charge most of the winter

 

HI MATE, thanks for your reply, I have tried the kill switch both on and off ,no difference and have checked every fuse in the box with a tester, still nothing.Also, cant find where the small earth wire connects to ???.Everything was working fine when I parked her up which is really frustrating!!
