If you find that a fuse is not receiving B+, use the Power Source system circuit diagram in Section I for fusible link information. This color wiring diagram contains all of the features and location information found in each system circuit diagram. You can also use the Power Source (Current Flow) chart in Section H. The flow chart located at the beginning of Section H also traces the B+ side of the fuse to its fusible link source. But, because it does not have all the features of the Power Source System Circuit Diagram (such as connector ID's, splice ID's, wire colors, and support sections), it is not as useful.
Ground Distribution in the electrical system, a load's ground point is often shared with other circuits. If another circuit which shares the ground point with your inoperative circuit works properly, then you know that the grounding point is OK. This does not eliminate the possibility of a problem on the ground side of the circuit, or a poor connection problem between ground point terminals "stacked" onto a single ground point.
