1H-7 Ignition System:
Tester knob indication: Voltage ( )
5) Measure the ignition coils primary peak voltage in
the following procedures:
WARNING
!
Do not touch the tester probes and spark
plug to prevent an electric shock while
testing.
a) Shift the transmission to the neutral, turn the
ignition switch ON and grasp the clutch lever.
b) Press the starter button and allow the engine to
crank for a few seconds, and then measure the
ignition coil primary peak voltage.
6) Repeat the b) procedure few times and measure the
highest peak voltage.
If the voltage is lower than standard range, inspect
the ignition coil and the CKP sensor.
Ignition coil primary peak voltage
150 V and more
7) After measuring the ignition coil primary peak
voltage, reinstall the removed parts.
Ignition Coil Resistance
1) Disconnect the spark plug caps. Refer to “Spark Plug
Cap and Spark Plug Removal and Installation
(Page 1H-5)”.
2) Disconnect the ignition coil lead wire couplers (1).
3) Measure the ignition coil resistance in both the
primary and secondary windings. If the resistance is
not within the standard range, replace the ignition
coil with a new one.
