Hull/Turret Slip Ring Index. The hull/turret slip ring index
identifies the electrical connections between the hull and the
turret found in the wiring diagram.
You find this index on
sheet 3 of the hull elementary wiring diagram. It gives the
pin identification on connector J3, the function it controls,
the slip ring number, and the sheet number(s) where you find
the slip ring.
This completes part B. This lesson continues with part C,
Tracing Electrical Circuits.
PART C - TRACING ELECTRICAL CIRCUITS
1.
Introduction.
This part of the lesson uses a unit level functional schematic
diagram and direct support/general support level wiring diagram to
trace electrical circuits. Before proceeding any further, make sure
you review the electrical symbols given in appendix A, just as you
should prior to tracing any electrical circuits in your unit. Do not
memorize the electrical symbols; you should always have the technical
manual on hand when tracing circuits.

Unit Level Functional Schematic Diagram.
For this part of the lesson, you must use FO-6, Hull Electrical
System - Power Distribution and Master Power Control Circuit
Functional Schematic Diagram (Unit Level)(shown in appendix A).
Begin tracing the system at the left side of the diagram by finding
the enclosure lines for the battery compartment.
You must remember
the diagrams show only the components that pertain to the circuit on
the diagram.
In many cases, the electrical assemblies house
additional components used in other circuits.
Battery Box Enclosure.
Inside this enclosure you will find
the symbol for part of a bus strip, the battery connections
(2BT101 through 2BT106).
The diagram shows how you must
connect the batteries: in series-parallel.
In the enclosure lines for the battery box you also will find
two types of symbols for electrical connections. Look at the
positive connections for 2BT101 through 2BT103; the lines go
to a clear circle, the first symbol for an electrical
connection.
Follow the three positive lines off these
connections to where they join into one
