IGNITION COIL INSPECTION
Remove the fan cover (page 5-2).
PRIMARY SIDE
Disconnect the ignition coil connector (1).
Measure the resistance of the primary coil by attaching
one ohmmeter probe to the ignition coil wire terminal (2)
and the other at the iron core (3).
RESISTANCE: 0.6 – 0.9 Ω
If measured resistance is out of specification, replace
the ignition coil (page 8-3).
SECONDARY SIDE
Disconnect the spark plug cap from the high-tension
cord (1).
Measure the resistance of the secondary coil by
attaching one ohmmeter probe to the high-tension cord
and the other at the iron core (2).
RESISTANCE: 5.6 – 6.9 kΩ
If measured resistance is out of specification, replace
the ignition coil (page 8-3).
OIL LEVEL SWITCH INSPECTION
Check the oil level (page 3-3).
Disconnect the Oil Alert unit connector (1).
Check the continuity between the oil level switch
connector and engine ground.
There should be no continuity when the engine is full of
oil.
Drain the engine oil completely (page 3-3).
Check the continuity between the oil level switch
connector and engine ground.
There should be continuity.
Check the continuity between the oil level switch
connector and engine ground while filling the engine
with oil.
The ohmmeter reading should go from continuity to no
continuity as the oil is filled.
If the correct continuity is not obtained, replace the oil
level switch (page 8-6).
