5.4.1 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 chassis as much as possible, taking care to:
- remove the paint on the chassis side and also the terminal side mechanically by sanding and/or by using an appropriate chemical
product to create a contact surface without notches or steps;
- apply a suitable paint with high electric conductivity properties between the cable terminal and the metal surface;
- connect the earth within 5 minutes of 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.
Additional signal grounds must be positioned at different points from the power grounds.
