f.
As
magnetic flux rapidly
nears
zero; the voltage
level for
spark
discharge
is
not maintained and
is
stopped.
g.
The
energy
in
the
windings
due
to
the
smdll
residual
flux generates
an
attenuation vibration
in
the secondary and primary windings and
diminishes
as
a resistance
loss
in
the
circuit.
h.
Then,
through
the
circuit period determined
by
the
cam
circuit angle, it again repeats
the
above
process.

Ignition coil handling
a.
Unless
the
ignition coil
is
damaged or
the
insula·
tion
is
affected by oily
residue
adhering around
the terminal, ignition performance
will
not deterio-
rate.
b.
The
quantitative
judgment
of
performance coil
testing
can
be conducted
by
employment
of
the
service tester.
The
test
can
be performed
by
allowing
spark
generation between needles
(31
while
the
interrupter
is
in
operation. {Refer
to
Fig. 5. 11)

The
rubber cap attached to
the
connecting ter-
minal
avoids insulator induction objects. {Refer
