Component Locator
Diagrams
The schematic diagram and circuit board component location illustrations
have grids. A lookup table
is
provided for ease of locating a component. The
circuit board illustration only appears once; its lookup table lists the diagram
number of
all
diagrams that the circuitry appears on.
9-2
Some of the circuit board component location illustrations are expanded and
divided into several parts to make it easier for you to locate
small compo-
nents.
To
determine which part of the whole locator diagram you are looking
at, refer to the
small locator key positioned at the upper left of each circuit
board component locator diagram,
as
shown
in
Figure
9-2.
The gray block,
within the larger circuit board outline, shows where that part fits
in
the whole
locator diagram. Each part
in
the key
is
labeled with
an
identifying letter
which appears
in
the figure titles under component locator diagrams.
