How to Find and Use These Diagrams

Diagrams are presented in three main categories:
- Power Distribution Diagrams
- System Diagrams
- Grounds Diagrams

Diagram 13-7 (Sample Power Distribution Diagram Page):

Power Distribution Diagrams
Provide the circuit details of how the system diagrams are powered. The power distribution source is shown at the top of a diagram page. All wires, connectors, and splices are shown in the same manner that the current flows, ending at the component/system being powered near the bottom of a diagram page. Circuits that go from one diagram page to another will be marked with large arrow heads indicating which diagram page the circuit went to/came from.

The power distribution diagrams can be found at Starting and Charging/Power and Ground Distribution, or by following the hyperlinks at the top of the diagram pages within the system diagrams.

Diagram 85-1 (Sample System Diagram Page):

System Diagrams
Components that work together are shown together in a system/subsystem diagram or set of diagrams. The system feed (circuit breaker, fuse, etc.) is shown at the top of a diagram page. All wires, connectors, components, and splices are shown in the same manner that the current flows, ending at the ground at the bottom of a diagram page. Circuits that go from one diagram page to another will be marked with large arrow heads indicating which diagram page the circuit went to/came from.

The system diagrams can be found at the specific Alldata System/SubSystem that they are most closely related to, such as Cruise Control, Powertrain Management, Radio/Stereo, etc.

Diagram 10-1 (Sample Grounds Diagram Page):

Grounds Diagrams
Provide the circuit details of how the system diagrams are grounded. This information is useful for checking interconnections of the grounding circuits of different systems. The components/systems being grounded are shown at the top of a diagram page. All wires, connectors, and splices are shown in the same manner that the current flows, ending at the ground at the bottom of a diagram page. Circuits that go from one diagram page to another will be marked with large arrow heads indicating which diagram page the circuit went to/came from.

The grounds diagrams can be found at Starting and Charging/Power and Ground Distribution, or by following the hyperlinks at the bottom of the diagram pages within the system diagrams.
