IGNITION COIL

1) Pull out high-tension cord by gripping its cap.
2) Disconnect ignition coil coupler.
3) Measure primary and secondary coil resistances.
Ignition coil resistance (at 20_C, 68_F)
Primary
Secondary : 11.2 – 15.2 kΩ
4) If resistance is out of specification, replace coil with new one.

IGNITER

Before this inspection, prepare 5 V power supply (3 new 1.5 V bat-
teries), one 12 V 3.4 W light bulb and one 12 V battery (fully
charged).
1) Disconnect igniter coupler (1).
2) Remove igniter (2) from its bracket.
3) Arrange 3 new batteries in series (1) (check total voltage is about
4.7 V).
4) Connect light bulb (2) between "c" terminal of igniter (3) and bat-
tery (4) positive (+) terminal, then connect battery negative (–)
terminal to igniter body.
Also connect battery positive (+) terminal and "b" terminal of ig-
niter.
Check that the light bulb does not illuminate.
5) Connect negative (–) terminal of batteries (1) and igniter body.
Check that the light bulb illuminate when positive (+) terminal of
batteries (1) is connected to "a" terminal of igniter.
If inspection result is not satisfactory, replace igniter.
6) Install igniter and connect igniter coupler.
