IGNITION COIL INSPECTION
● Remove the seat lock with the main key.
● Remove the luggage box.
● Remove the center cover.
● Remove the primary wire.
·Since the resistance value of the primary coil is
inherently very small, it is difficult to distinguish it
from a shorted wire.
● 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 :
● 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 : 17~21 ㏀
● 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 : 12~16 ㏀
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.
