IGNITION SYSTEM
IGNITION COIL INSPECTION
Remove the luggage box.
Remove the primary wire.
NOTE
Measure the peak voltage of the ignition coil primary
side first.
Since the resistance value of the primary coil is
inherently very small, it is difficult to distinguish it
from a shorted wire.
PRIMARY COIL INSPECTION
Measure the resistance between the two terminals of
the ignition primary coil.
If the resistance value is within the specified range the
coil is good.
If resistance is
(infinite), replace the coil with a new
one.
STANDARD VALUE : 0.1~0.5
SECONDARY COIL INSPECTION
With the spark plug cap on, measure the resistance
between the primary coil terminal and the spark plug
cap.
If the resistance value is within the specified range,
then the coil is good.
If the resistance is
(open wire), disconnect the spark
plug cap and measure the secondary coil resistance.
STANDARD VALUE : 6.5~9.8
Measure resistance between the primary coil terminal
and high-tension cord.
If the resistance value is within the specified range,
then the coil is good.
If the resistance is
(open wire), replace the coil with
a new one.
STANDARD VALUE : 2.7~3.5
REPLACEMENT
Remove the high-tension cord from the plug, remove
the plug cap.
Remove the wire from the ignition coil.
Remove the primary wire from the ignition coil.
Loosen the ignition coil fixing bolt securing the frame,
Remove the ignition coil.
Install in the reverse order of removal.
