HOW TO USE THIS VOLUME (cent)

CHAPTERS

Each chapter contains paragraphs. Chapter 1 contains general information, a symbols chart, connector endviews and effectivity codes.

SECTIONS

Depending upon the subject matter under examination, chapters may employ sections to separate andhighlight major categories of information and also to promote understanding.

SECTION NUMBERING

Sections are numbered with Roman numerals (Section I, Section II, etc.).

PARAGRAPHS

Paragraphs make up chapters. It is the paragraphs that have the information you need for any job. USE THEINDEX TO FIND THE PARAGRAPH YOU NEED. DONT USE THE PAGE NUMBERS.

PARAGRAPH NUMBERING

Paragraph numbers are in two parts. The first number is the chapter, The second number is the paragraph.Each number is separated by a dash as shown in the example.

Paragraph numbers are the most important numbers in the volume. Always use the paragraph number to findinformation – NOT the page number.

PAGE NUMBERING

All page numbering is done by chapters. Paragraph numerals are not included in the page numbers. The firstnumber represents the chapter the second number represents the page in that chapter. The numbers areseparated by a dash as shown in the example.

NOTE

Page numbers are not used to find information. Instead, use paragraph numbers.

SYMBOLS CHART

Symbols used in the wiring diagrams are shown in a symbol chart. If you need symbol information, refer to thesymbol chart located in Chapter 1.

CONNECTOR END VIEWS

This volume contains connector end views with a directory. The directory is in alphabetical order by referencedesignator (REF DES). The directory also lists the wire (WIRE) harness (lIARN) number (NO.) and connector(CONN) code (CODE). If you require connector information, lookup the reference designator in the directory,then refer to the connector end view illustration listed under the connector code.

Example:

CONN WIREREF HARN CONNDES NO. CODE

J1 W619 FL

AH-64A HELICOPTER EFFECTIVITY CODES

Helicopter effectivity codes designate differences between helicopters by helicopter serial numbers, These codesconsist of three letters and represent various helicopter serial number blocks. They are used throughout thisvolume as necessary to aid in the helicopter troubleshooting effort.

These codes are used to designate serial number block differences.

These codes are placed on the line between line replaceable units (LRUs) or within the LRU.

To use the helicopter effectivity codes, note the helicopter serial number on the tail of the helicopter. Use thisserial number to determine which path in a wiring diagram to follow.

WIRING DIAGRAM DIRECTORY

The wiring diagram directory is in alphabetical order by reference designator (REF DES). Looking up thereference designator of a connector, splice, ground stud, circuit breaker, component, or LRU provides you withthe cable reference, paragraph number and the applicable wiring diagram.

HOW TO USE THIS VOLUME (cont)

WIRING DIAGRAMS

The wiring diagrams provide you with point-to-point wiring for each aircraft system. The wiring diagramsdepict LRUS, connectors, splices, shielding, ground studs, MRTU interfacing and terminal boards.

Highway use (fig. 1-1). The alpha character identifies a specific line, and the number in parenthesis identifiesthe sheet number where the signal terminates.

Example: pin 1 and pin 1S.

Figure 1-2. Triaxial Connector

Figure 1-1. Highway Use

Triaxial connectors (fig. 1-2) and some coaxial connectors are shown in the wiring diagrams with two pins.

Pin 1 is located inside pin 1S with the shield attached to pin 1S. In triaxial connectors, the second shield isattached to the case and is not identified by a pin number or letter.

M50–261

Electrical connections at terminal boards are typically shown (fig. 1-3) as follows:

1. Vertical and horizontal lines indicate electrical separation between terminals and blocks ofterminals.

2. Absence of lines indicates no separation.

3. Terminal board connections may be illustrated horizontally, vertically or a combination of both.

WIRE HARNESS DIAGRAMS

Wire harness diagrams show the approximate location and routing of all connectors and components located ona wire harness. The components and connectors are referenced to fuselage station (FS), waterline (WL) andbutt line (BL). Forward and aft views which refer to forward and aft in the helicopter, are used in the wireharness diagrams. Where required for clarity, FWD and AFT arrows are used.APPENDIX

Appendix A contains a list of other manuals you might need to do your job.

GLOSSARY

The glossary for this volume contains a list of abbreviations and acronyms. Abbreviations are shortened termsfor words. Acronyms are shortened terms for several words and usually use only the first letter of each word.Abbreviations and acronyms are defined the first time they are used within the text of the chapter where theyare found. The list in the glossary however, provides a good place to check if there is any doubt. The glossaryalso contains definitions of unusual terms that appear in the volume. Check the list of definitions if you see aword in the volume that you’re not sure of. It is always a good idea to look over the glossary and becomefamiliar with abbreviations, acronyms and unusual terms.

INDEX

The index for TM 1-1520-238-T-10 is at the end of this volume. The index lists all paragraph titles inalphabetical order. After you find the paragraph title in the index, the appropriate paragraph is indicated. Forexample, if you need wiring information on the Air Data System, go to the A section of the index and lookunder Air Data System (ADS). There you will find:
