Electrical Schematics

Electrical Schematic Diagram:

IMPORTANT: The schematic does not represent the components and wiring as they physically appear on the vehicle. For example, a 4-foot length of wire is treated no differently in a schematic from one which is only a few inches long.

The wiring schematic is the cornerstone of electrical diagnosis. Schematics break the entire electrical system into individual circuits, showing the electrical current paths when a circuit is operating properly. Wiring which is not pant of the circuit of interest is referenced to another page where the circuit is shown complete. Schematics use a top (power) to bottom (ground) sequence to present electrical information.

When diagnosing a horn problem use the service information located in the Horns service category. The following schematic is a typical example of a schematic with its supporting text.
