(2) Removal of resistive cords and ignition coils
q
Disconnect the resistive cord from the ignition coil.
w
Remove the No. 1 and No. 3 resistive cords by dis-
connecting the connectors from the ignition coils
and spark plugs.
CAUTION:
·
Never disconnect the resistive cords by holding the
cord section of the resistive cords.
e
Disconnect the connectors from the ignition coils.
r
Remove the ignition coils on the spark plugs of
No. 2 and No. 4 cylinders by removing the attach-
ing nuts.
(3) Measurement of insulation resistance
Measure the insulation resistance of each spark plug,
using a megger (Insulation resistance meter) and en-
sure that the measured insulation resistance of each
spark plug is more than the specified value.
Minimum Insulation Resistance:
20 M
W
If the measured insulation resistance is less than
15 M
W
proceed to the step (4) onward.
If the measured insulation resistance is more than the
specified value, proceed to the step (4) onward except
the step (8).
When a megger is not available:
q
Start the engine. Warm up the engine completely.
w
Race the engine at 4000 rpm for five seconds.
e
Stop the engine.
r
Remove the air cleaner.(Refer to the removal of the
air cleaner.)
t
Remove the resistive cords and ignition coils.
(Refer to the check and adjustment of the valve
clearance section for the removal of the ignition
coil and resistive cord.)
y
Remove the spark plug, using a suitable spark
plug wrench or the following SST.
SST: 09268-87703-000
WARNING:
·
Be very careful not to get scalded with hot spark plugs,
since spark plugs are hot.
u
Visually inspect the spark plug.
If the electrode is dry: Proceed to the step (6)
(Satisfactory)
If the electrode is wet: Proceed to the step (5).
