The example above tells you that you are looking at the hull

elementary wiring diagram used at the DS/GS levels of maintenance,

and that you have the first of 30 sheets that make up the complete

wiring diagram.

2.

Symbols.

In the schematics and wiring diagrams you use to maintain and repair

the tank's electrical system, different symbols show the purpose of

the components. Some schematics and wiring diagrams give examples of

the symbols used on the first page.

If the schematic or wiring

diagram does not list and identify its symbols, refer to Appendix A

of TM 9-2350-264-24-1 for a listing of the symbols used. (See sheet

1 of the hull elementary wiring diagram (extracted from TM 9-2350-

264-24-1) in appendix A of this lesson, for examples.)

Location Symbols. When a schematic or wiring diagram has two

or more sheets, you must have a way to locate a circuit when

it continues on another sheet.

Additionally, you must have

the same capability when a circuit continues at a different

point on the same sheet.

The schematics or wiring diagram may show the highest find

number used also.

For example, look at sheet 1 of the hull

elementary wiring diagram.

At the lower right side of this

sheet, you find the highest find number it uses (151).

Find and sheet numbers.

The schematics and wiring

diagrams use a circle, with a horizontal line through the

center, as the symbol indicating a circuit continues on

another sheet of the diagram.

The number in the top

portion of the symbol shows the reference number to find

on the new sheet. The number in the bottom portion of the

symbol shows the sheet number on-which the circuit

continues. For example:

The example above indicates the circuit continues on sheet number 2

and you must look for find number 1.
