2.3 Ignition system
inspection
* Attention
When the spark plug is not sparking, check
if components of wiring are loosened or
badly contacted and make sure all the
voltage values are normal.
There are many brands of multimeters with
different interior impedance. The values they
measured are not the same.
Connect a high-voltage shunt or an ammeter with input impedance higher than 10MΩ 10CV to the
multimeter.
2.3.1 Primary voltage of ignition coil
If an old spark plug is removed and replaced with a good one,
ground it with engine.
* Attention
Test when wirings of all the circuits are correct.
Normal cylinder compression pressure means to test
with spark plug installed on the cylinder head.
Connect lead wire of ignition coil and a shunt is connected
between terminal (black/white) of primary coil and grounding wire of vehicle block.
Press starter motor button or kick starter pedal to measure primary peak voltage of ignition coil.
Min. voltage: higher than 95V.
