Remove the front cover.
Remove the spark plug cap.
Disconnect the ignition coil wires.
Measure the resistance between the ignition
coil primary coil terminals.
Resistance: 0.20.3Ω/20
Remove the spark plug cap and measure the
secondary coil resistance between the spark
plug wire and the primary coil terminal.
Resistance: 3.24.8KΩ/20
Measure the spark plug cap resistance.
Remove the spark plug cap and measure the
spark plug resistance.
Resistance: 4.25.2KΩ/20
PERFORMANCE TEST
Test the performance with a CDI tester.
If the spark is weak, inspect the spark plug
and CDI unit. If both of them are normal,
replace the ignition coil with a new one.
This test is to inspect the continuity of
ignition coil.

This test is for reference only. Accurate
test should be performed with a CDI
tester.

Measure the resistance in the XKΩ range
of the electric tester.

• Operate the CDI tester by following
the manufacturer‘s instructions.
• Use the special connector to connect
the CDI unit.
