14-12 ELECTRICAL SYSTEM
Ignition Coil Arcing Distance Inspection
O
The most accurate test
for
determining
the
condition of
th
e
ignition
coil
is
made bV
measuring
arcing distance
using a suitable
commerciallv
available
coil tester for the
3-needle method.
Remove the
ignition coil.
Connect
the
ignition coil
[A
]
(with
the
spark plug cap left Installed on
the spark plug lead) to the lester
[B],
and measure the arcing
distance.
*
If the distance
reading
is
less
than
the
specified value, the
ignition coil
or spark plug
cap is
defective.
Ignition Coli Arcing Distance
Standard:
8 mm
or more
e
Ta determine which
part
is
defective,
measure the
arcing
distance
again with the
spark
plug cap removed from the
ignition
cOil lead.
Remove the cap
by
turning
it counterclockwise.
*
If the arcing distance
is
subnormal
as before,
the
trouble
is with
the
ignition coil
itself.
If the arcing distance
is
now
normal, the
trouble
is
with the spark plug
cap.
Ignition Cot! Resistance Inspection
*If the coil tester
is
not
available,
the coil
can
be
checked for a broken
or
badly shorted winding with the hand
tester. However,
the hand
tester cannot
detect
layer
shorts
and
shorts resulting
from insulation
breakdown under high
voltage.

Remove the ignition coil [A]
.
Measure the primary
winding
resistance
[B).
o
Set the meter to the
x
1 0
range,
and read the
tester.
Measure the secondary winding resistance
[C].
o
Remove the spark plug cap by turning it
counterclockwise.
o
Set the tester to the
x
1
kO
range,
and read
the
tester.
*
If the tester does not
read as
specified, replace
the
coil.
*
If the tester reads
as
specified,
the ignition
coil windings are probably
good.
However,
if
the ignition
system still does
not
perform
as
it
should
aher all other components
have been checked, test replace
the
coil
with one known to be
good.

Check the
spark
plug lead for
visible
damage.
* If the spark plug lead is
damaged.
replace
the
coil.
Spark Plug Cleaning and Inspection
Remove the spark plug, and visually inspect
it
.
• Clean
the spark p,lug, preferably in
8
sandblasting
device,
and
then
clean
off any abrasive
particles.
The plug may also
be cleaned
using
a high flash -point solvent and
a
wire brush or
other suitable tool.
*If the center

ara corroded
or
damaged,
or
if
the
inSUlator

is
cracked,
replace
the plug.
Use the
standard
spark
plug.
