number, terminal or cable connection and function in accordance with the
numbering system used throughout the training device. Figure 14 is a sample
of a wire list.
3.3.1.7.7.1 Wiring lists. (F) Wiring lists in lieu of wiring diagrams
shall not be accepted except as authorized by the contracting activity. If
authorized, incorporation shall be by reference to applicable engineering
document number and nomenclature only.

ac power, direct current (de) power, and grounding systems (see figure 15).
The following shall apply for the preparation of power distribution diagrams:
a.
Show total distribution from power sources to the various
assemblies, subassemblies, and modules.
b.
Show and identify all power line devices such as fuses, circuit

Show all relay or contactor coils in series with the main power
j.
distribution path.
3.3.1.7.9 Fault logic diagrams. Fault logic diagrams shall be based on
fault indications observed during troubleshooting. The diagrams shall
comprise a branching series of questions pertaining to fault isolation (see
figure 16). Each question shall pertain to a further observation or
measurement and shall result in a "yes" or "no" answer, thereby progressively
