NOTE
•
If
there
is
no spark
at all
plugs,
check
all
connections
for
loose or
poor
contact before measuring each peak
volt-
age.
•
If
using the
peak
voltage adaptor,
use
the
recommended
digital
multimeter
or
commercially
available
digital
mul-
timeter with
an impedance
of
10
MO/DCV
minimum.
•
The
display
value
differs
depending
upon
the internal
impedanco
of

•
If
using Imrie diagnostic tester
(model
625),
follow the
manufacturer's
instructions.

NOTE
•
Check
ell
system connections
before
inspection.
If
the
sys-
tem
is
disconnected,
incorrect peak
voltage
might be
mea-
sured.
•
Check
cylinder
compression
and
check
that the
spark
plugs are
installed correctly.
Shift
the
transmission
into neutral, disconnect
the
spark
plug caps from
the spark plugs.
Connect
a
good known
spark plug
to
the spark plug cap
and
ground
the spark plug
to
the cylinder as
done
In
a
spark
test.
Remove
the
rubber boot
from one
ignition
coil.
With
the ignition

Avoid
touching the spark plugs
and
tester
probes
to
prevent elec-
tric
shock.
If

is
abnormal, check
for
an open
circuit
or
poorly
connected connectors
in
Bleck/Yellow
wires.
If
no
defects are
found
in
