The ground points on a car are a vital part of the car electrical system as all sub-system voltage levels have the ground point as a reference (0 V).
The illustration shows a ground point screw connection of the type found on the cylinder block (upper illustrations) and to the body (lower illustration).
The arrowed lines show the path of the electric current through the contact point.
A poor contact on the ground point will have a negative impact on the car electrical systems. It is therefore very important that the ground point contact
is in good order, that the screw is tight and the cable terminal is correctly crimped to the cable.
Especially important are ground points where several wires are connected to one ground point.
Note! There should be no oxidization between the cable terminals and the screw head.
Installation
Always clean around screws, nuts and contact surfaces.
