Earth Points
There are only two earth connections to the chassis, one at the front for the battery earth lead, and one at
the left hand side of the engine bay for the engine earth braid, and rear harness earthing requirements. At both
points, the anodised surface treatment must be removed from the chassis before an M8 Pulsert is fitted, with
a special stepped washer being used to clamp directly against the chassis surface. After assembly, coat the
chassis and cable terminals with petroleum jelly to protect from corrosion.
