ITEM FAILURE
CAUSE
TO
DO
Ignition coil
High voltage to
low
The interior resistance is too low and test it
with a designated tester.
Replace
The cranking speed is too low.
Search for error and repair
The tester is disturbed
If the voltage measured for sev-
eral times is above standard,
then the value is normal.
Poor contact of ignition system wire
Check and repair
Bad act of the ignition coil
Check and replace
Bad act of the charge coil
Peak voltage test
Side voltage
No high voltage,
off-and-on high
voltage
Connecting error in tester
Check and repair
Bad act of the main switch
Check and replace

Check and repair
Short circuit or poor contact of CDI ground wire Check, repair or replace
Bad act of charge coil
Peak voltage test
Bad act of trigger
Peak voltage test
Bad act of connector for high voltage wire
Check, repair or replace
Bad act of CDI group (when items abnormal or
when there is no spark in the spark plug)
Replace
Normal high volt-
age, no spark
Bad act of spark plug or power leak in second-
ary coil
Check and replace
Bad act of ignition coil
Check and replace
Charge coil
