3 IGNITION CIRCUIT

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.
3. 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.

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