TROUBLESHOOTING
Most

are
identified
by
numbers
on
the
compo-

and

.

are

and

in
numerous
places
throughout

.
Most

are
listed

(infinite

orfor

that

circuit
.
Electric
current
is
logical
in
its
flow,
always
moving
from
the
voltage
sourcetoward
ground
.
Electricalfaults
can
usually
be
located
through
a
process
of
elimination
.
When
troubleshoot-
ing
a
complex
circuit,
separate
the
circuit
into
smaller
parts
.
The
general
testsoutlined
below
may
be
helpful
in
finding
electrical
problems
.
The
information
is
most
helpful
when
used
with
the
wiring
diagrams
.
Be
sure
to
analyze
the
problem
.
Use
the
wiring
diagrams
to
determine
the
most
likely
cause
.
Getan
understanding
of
how
the
circuit
works
by
following
the
circuit
from
groundback
to
the
power
source
.
When
making
test
connections
at
connectors
andcompo-
nents,
use
care
to
avoidspreading
or
damaging
the
connec-
tors
or
terminals
.
Some
tests
may
require
jumper
wires
to
bypass
components
or
connections
in
the
wiring
harness
.
When
connecting
jumper
wires,
use
bladeconnectors
at
the
wire
ends
that
match
the
size
of
the
terminal
being
tested
.
The
small
interna¡
contacts
are
easily
spread
apart,
and
this
can
cause
intermittent
or
faultyconnections
that
can
leadto
more
problems
.
