INSPECTION
IGNITION COIL PRIMARY PEAK VOLTAGE
• Remove the air cleaner box. ( 5-14)
• Disconnect all the ignition coil/plug cap lead wire couplers
before removing the ignition coil/plug caps.
• Remove all of the ignition coil/plug caps.
• Connect the new four spark plugs to each ignition coil/plug cap.
• Connect all the ignition coil/plug cap lead wire couplers to the
ignition coil/plug caps respectively, and ground them on the
cylinder head (each spark plug hole).
NOTE:
Be sure that all couplers and spark plugs are connected properly
and the battery used is in fully-charged condition.
Inspect each ignition coil primary peak voltage at the ignition
coil/plug cap coupler.
• Connect the multi-circuit tester with peak voltage adaptor as
follows.
No.1 ignition coil/plug cap:
W/Bl wire terminal ( Probe) – Ground ( Probe) terminal
No.2 ignition coil/plug cap:
B wire terminal ( Probe) – Ground ( Probe) terminal
No.3 ignition coil/plug cap:
Y wire terminal ( Probe) – Ground ( Probe) terminal
No.4 ignition coil/plug cap:
G wire terminal ( Probe) – Ground ( Probe) terminal
09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
* Do not remove the ignition coil/plug cap before dis-
connecting the lead wire coupler, or the lead wire will
be damaged.
* Do not pry up the ignition coil/plug cap with a screw-
driver or a bar to avoid damage.
* Be careful not to drop the ignition coil/plug cap as it
may open or short in a circuit.
Avoid grounding the spark plugs and suppling the
electrical shock to the cylinder head cover (magne-
sium parts) to prevent the magnesium material from
damage.
