IGNITION SYSTEM
IGNITION COIL INSPECTION
●
Remove the seat lock with the main key.
●
Remove the luggage box.
●
Remove the center cover.
●
Remove the primary 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 : 1.5~3.5
Ω
●
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.
·
Since the resistance value of the primary coil is
inherently very small, it is difficult to distinguish it
from a shorted wire.
