Inspection of Ignition System
Note:
If the spark plug generates no spark, check first
if there is come-off, loosening or poor contact
with the wiring, then measure the peak voltage.
Different multimeter has different input resis-
tance and shows different readings. Measure with
digital multimeter with input impedance over
Connect peak voltage oscillograph with digital
multimeter.
Special Tool:
Peak Voltage Oscillograph 519-922-150000
(Use together with digital multimeter available
from the market with input impedance over

gnition Coil Primary Voltage
Note:
Measure after all the wires are correctly
connected.
Inspection should be done when the spark plug
and spark plug cap are properly installed. If the
spark plug is removed, the peak voltage will rise.
Remove left side panel.(2-8)
Keep spark plug in the cylinder head, install qualified
spark plug on the spark plug cap and earth the engine.
Open rubber cover of ignition coil, keep the ignition
wire connected, and connect peak voltage oscillograph
between primary wire terminal and frame body earth
wire.
