LIST
OF ASSEMBLIES
A list
Of
assemblies can be found at the beginning of the
Electrical Parts List. The assemblies are listed in numerical
order.
When
the
completecomponent number of a part is
known,
this list
will identify the assembly in which the pert is located.
Only
the circuit number will appear on the dlagrams and
circuit board
illustrations. Each
dlagram and circutt board
illustration is clearly marked with the assembly number.
Assembly numbers are also marked on
the
mechanical
exploded
views located in the Mechanical Parts List The component
number is obtained by adding
the
assembly number prefix to the
circuit number.
The
Electrical
Parts List Is divided and arranged by
assemblies In numerical sequence ( e . ~ . , assembly A1 with Its
subassemblies
and
parts, precedes assembly
A2 with its sub-
assemblies
and parts).
Chassis-mounted parts have no assembly number prefix
and are located at the end of the Electrical Parts Llst.
