Hi! Re : earth wire :
From memory , I made up a new earth wire because my old one was in a very poor condition , by drilling a hole to fit a new self-tapping screw between the coil leads for easy screwdriver access at the front of the plate and then measuring and making a new lead to fit the inlet manifold clamp-up bolt/nut on the cylinder head . It's a very good idea to check the continuity at this point as it is now very easy to repair/check/clean -not forgetting that the plate is electrically insulated by the rubber mounting grommets . No starting problems now , especially since I fitted the relay mod to the starter, kicks in every time now!
