Check resistance between ignition coil terminals as per the following.
Is the Inspection result normal?
YES >> GO TO 2.
NO >> Replace malfunctioning ignition coil with power transistor. 2.CHECK IGNITION COIL WITH POWER TRANSISTOR-II
CAUTION: Perform the following procedure in a place with no combustible objects and good ventilation.
Fix ignition coil using a rope etc. with gap of 13 - 17 mm (0.52 -0.66 in) between the edge of the spark plug and grounded metal portion as shown in the figure.
Crank engine for approximately 3 seconds, and check whether spark is generated between the spark plug and the grounded metal portion.
Spark should be generated.
CAUTION:
Never place the spark plug and the ignition coil within 50 cm (19.7 in) each other. Be careful not to get an electrical shock while checking, because the electrical discharge voltage becomes 20 kV or more.
It might damage the ignition coil if the gap of more than 17 mm (0.66 in) is made.
NOTE:
When the gap is less than 13 mm (0.52 in) , a spark might be generated even if the coil is malfunctioning.
Is the Inspection result normal?
YES >> Inspection END
NO >> Replace malfunctioning ignition coil with power transistor.
