CHECKING THE IGNITION COIL ASSEMBLY
WITH POCKET TESTER
l
The ignition coil is mounted on the right side of
the frame below the fuel tank assembly, near
the cylinder head assembly. (Fig. 5.11)
l
Disconnect the wiring socket connecting TCI
unit and the ignition coil. Also disconnect the
HT cord from the spark plug.
Pocket tester
l
Set Pocket tester at 200 ohms position.
l
Connect the pocket tester’s ‘+ve‘ and ‘–ve‘
lead to the terminals of the ignition coil coupler
as shown to measure the primary winding
resistance. (Fig. 5.12) If the resistance is not
within the specified limit, replace the ignition
coil assembly with a new one.
Primary resistance
4.05 ~ 4.95 ohms
l
If primary winding resistance is OK, then check
the secondary winding resistance.
l
Set pocket tester at 20k ohms position.
l
Remove the suppressor cap from the HT card.
Connect the pocket tester ‘+ve‘ lead to the HT
cord and ‘–ve‘ lead to any terminal of the
ignition coil coupler and measure the
resistance. (Fig. 5.13)
Secondary resistance
k ohms
10.8 ~ 12.32
l
If resistance of the windings are not within the
limit, replace ignition coil assembly with a new.
SPARK PLUG
l
Neglecting the sparkplug leads to poor
performance of engine. If the sparkplug is used
for a longer period, the electrode gradually
burns away and carbon builds up along the

Caution:
Always use recommended make and
type of sparkplug only.
