Ground points
In general, original vehicle ground connections are not to be modified; in cases where these connections must be moved or new
connections added, use the holes present on the chassis to the extent possible, taking care to:
● mechanically remove - either by filing and/or with a suitable chemical based solution - the paint on both the chassis and ter-
minal side, thus creating a contact surface free of indentations and edges;
● paint the area between the terminal and metal surface with a suitable high conductivity paint
● connect to earth within 5 minutes after application of the paint.
As regards the signal related ground connections (e.g. sensors or low-absorption devices), do not use the standardized points Un-
der no circumstances use standardized points for engine ground connection and chassis ground connection.
Additional signal grounds must be positioned at different points from the power ground.
