MX’er SYSTEM
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.
PULSER COIL
INSPECTION
Remove the front cover.
Disconnect the pulser coil wire coupler and
measure the resistance between the blue/
yellow and green/white wire terminals.
Resistance: 50 60Ω
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.
