DESCRIPTION - EARTHS - Fiat 500 1.4 16v

The following diagram shows the various earths on the car. The associated circuits are shown for each earth.In this way it is easy to identify these circuits which are connected to earth by the same line; this facilitates the job of searching for faults if there are problems involving more than one function (for example, the oxidization of an earth may put various circuits, and numerous functions connected to them, out of operation simultaneously).
