DAELIM VJF125 Service Manual - Ignition Coil Inspection
18-4
IGNITION SYSTEM
REPLACEMENT
Remove the high-tension cord from the plug, remove
the plug cap.
Remove the primary wire from the ignition coil.
Loosen the ignition coil mounting bolt securing the
frame, remove the ignition coil.
Install in the reverse order of removal.
IGNITION COIL INSPECTION
Disconnect 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 :
0.73
0.08
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 :
15
1.25
Since the resistance value of the primary coil is small, it is
too diffcult to judgment even if the problem happen from
the short circuit.
Dont’t measure the secondary coil voltage of ignition coil
