IGNITION COIL INSPECTION
● Remove the luggage box ( 3-2)
● Remove the primary wire.
NOTE
•Since the resistance value of primary coil is
inherently very small, it is difficult to distinguish it
from a shorted wire.
● Measure the peak voltage of the ignition coil primary
side first.
● If the resistance value is withtin the specified range
the coil is good.
● It resistance ∞ (infinite), replace the coil with a new
one
STANDARD VALUE: 0.1~0.5 Ω Ω
● Remove spark plug cap from plug.
● On condition that there is plug cap, measure the
resistance between plug cap and the primary
terminal.
● If the resistance shows ∞ (open wire), pull out plug
cap and measure the secondary resistance.
STANDARD VALUE : 6.5~9.8 k k Ω Ω
● Measure resistance between the primary coil terminal
and high-tension cord.
● If the resistance is ∞ (open wire), replace the coil
with a new one.
STANDARD VALUE : 2.7~3.5 k k Ω Ω
● Check the primpary voltage of ignition coil.
● On condition that iginition cord is connected,
connect the peak voltage adaptor(+) cord to green
terminal, and (-) cord to black terminal. Then start
vehicle and check.
STANDARD VALUE : 100~250V

● 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.
