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
