Parts List Column Descriptions

Column Column Name Description

1Component Number The component number appears on diagrams and circuit board illustrations, located in the diagrams

section. Assembly numbers are clearly marked on each diagram and circuit board illustration in the

Diagrams section, and on the mechanical exploded views in the Replaceable Mechanical Parts list

section. The component number is obtained by adding the assembly number prefix to the circuit

number (see Component Number illustration following this table).

The electrical parts list is arranged by assemblies in numerical sequence (A1, with its subassem-

blies and parts, precedes A2, with its subassemblies and parts).

Chassis-mounted parts have no assembly number prefix, and they are located at the end of the

electrical parts list.

3 and 4 Serial Number Column three indicates the serial number at which the part was first effective. Column four indicates

the serial number at which the part was discontinued. No entry indicates the part is good for all

serial numbers.

A list of assemblies is located at the beginning of the electrical parts list. The

assemblies are listed in numerical order. When a part’s complete component

number is known, this list will identify the assembly in which the part is located.

Chassis-mounted parts and cable assemblies are located at the end of the

Replaceable Electrical Parts List.

The table titled Manufacturers Cross Index shows codes, names, and addresses

of manufacturers or vendors of components listed in the parts list.
