Ground Distribution

Typical Ground Distribution Schematic:

Figure shown is a sample Ground Distribution schematic for the Headlamps. It shows exactly which components share each ground. This information can often be a timesaver when troubleshooting ground circuits.

For example, if both Headlamps and the Park/Turn Lamp on one side are out, suspect an open in their

common ground wire or the ground connection itself. On the other hand, if one of the lamps work, the ground and the wire up to the splice are good. You have learned this just by inspecting the schematic and knowing the vehicle's symptoms. No actual work on the lighting system was needed.
