Ignition coil
inspection
The most
accurate
test for
determ ining Lhe
condition
of
the
ignition
coil
is
made with
the
Kawasaki Electro·
tester.
The
ignition
coil
must
be
connected
co
the
tester
in
accordance with
the
tester
directions
and
should
pro·
duce
at least
a 5
mm
spark.
Since
a
tester
other
than
the
Kawasaki
Electrotester
may
produce
a
different
arcing distance,
the
Kawasaki
Elcctrotester
is
recom
·
mended ror reliable
results.

Ignition
Coil
If
an Electrotester is
not
avai
lable,
the
coil can
be
checked
for
a broken or badly shorted winding with
an ohmmeter.
However, an
ohmmeter
cannot
de
tect
layer
shorts
and
shorts
resulting
from
insulation
break·
down
under high voltage.
To
measure the
primary
winding resistance:
•Remove
the
fuel
tank
(Pg.
39).
•Disconnect
the igni tion coil
leads.
•Set
the ohmmeter to
the
x
1
n
range,
and
connect
the ohmmeter
leads
to the
leads
from
one
of the
ignition coils.

To measure
the
secondary
winding resistance:
•Discon
nec
t the
spark
plug
caps
from
the
spark
plugs,
and
pul
l
the
spark
plug
leads
off
the
caps.
•Set
the ohmmeter to
the
x

kn range,
and connect
one ohmmeter
lead
to the spark plug lead
and
the
other
ohmmeter
lead
to the yell
ow/red
lead from
the
ignition
coil.

If

does
not

adequate
spark,
or
if either
the
primary
or
secondary winding does not
have
the correcL
resistance,
replace
the ignition
coil.
With
the
highest ohmmeter range, check
for
conti·
nuity
between
the

lead
and
the
coil core
and
between
each plug

and

If
there
is any
reading, the coil
is shorted and mu
st
be
replaced.
Also,
replace
the
ignition
coil if the spark plug lead
shows
visible damage.
Contact Breaker
Contact
breaker
inspection
When
the
points
become dirty, pitted, or
bu
rned,
or
if
the
spring
weakens,
th
e
poin
ts
will
not
make the
contact necessary to
produce
a
good
spark, resulting
in
unstable
idling,
misfiring, or
the engine
not
running
at
all.
Inspect
the
contact
breaker
in accordance
with
the
Period
ic
Main
tenance
Chart
(Pg.
10},
and
repair
or
repl
ace
if necessary.
Clean
the
points with clean
paper
or
cloth
using
an
oil-free solvent.
A
business
card soaked in
trichloro-
ethylene
can
be
used to
remove
traces
or
oil. To
repair
light
damage,
use fine emery cloth
or
an
oil
stone.
Ir
the

arc
badly
worn down
or
damaged,
or
if
the
spring
is weak,
replace
the contact
breaker.
