Ground Distribution
The Ground Distribution diagrams are found in "Starting and Charging, Power and Ground Distribution." These diagrams show which components share each ground point. This information can often be a time-saver when troubleshooting a poor ground. Diagrams
For example, if the Fuel Pump does not run, you may suspect an open in its circuit to ground. However, if the Number Plate Lamps work, and they share the same ground point as the Fuel Pump, you know that the ground and the wire up to the common splice are good. You have learned this just by inspecting the diagram and knowing the vehicle's symptoms.
