Note: Do not touch the test probes or
spark plug, in case of electric shock.
Z If the voltage is lower than the
standard value, check the ignition
coil and coupling coil.
Resistance of ignition coil
Z Disconnect the ignition coil wires
and spark plug cap. Remove the
ignition coil;
Z Measure the resistance of the
primary and secondary windings of
the ignition coil with the multimeter.
If the resistance of two coils is close
to the specified value, the ignition
coil is in good condition.
Resistance of ignition coil
Primary winding: 0.1-1.5 Ω (terminal
- ground)
Secondary coil: 12-22KΩ (terminal -
spark plug cap)
Peak voltage of coupling coil
Z Check the peak voltage of the
coupling coil with following steps.
Z As shown in right figure, connect
the multimeter with the peak
voltage adapter.
+Probe: Green wire
-Probe: Blue wire
Z Move the gear to the neutral
position, turn on the ignition
device.
Z Press the start button and crank the
engine for a few seconds, and then
measure the primary peak voltage
of the coupling coil;
Z Repeat the steps above for several
times. Measure the maximal value
of the primary peak voltage.
Put the multimeter at AC voltage step.
