2.16.1 Earth points
The vehicle’s original ground connections should not be modified in principle. In the event that such
connections need be displaced or addition ground points need be realized, use the holes found on the
chassisasmuchaspossible,takingcareto:
- remove by mechanical means, i.e. by using a file and/or a suitable chemical, the paint both on the
chassis side and on the terminal, until the anaphoretic paint is fully taken off the chassis, thus
obtaining a base surface f ree from nicks and steps;
- apply a suitable paint with high electric conductivity properties between the cable terminal and the
metal surface;
- connect the ground not later than 5 minutes after applying the paint.
As regards the signal- related ground connections (e.g. sensors or low-absorption devices), do not use the standardized points
for engine ground connection and chassis ground connection.
The additional signal grounds shall be positioned at different points from the power grounds.
