Ignition System
Measuring Coil Resistance
If the arcing tester is not available, the coil can be
checked for a broken or badly shorted winding with an
ohmmeter. However, an ohmmeter cannot detect layer
shorts and shorts resulting from insulation breakdown
under high voltage.
Remove the ignition coil (see Ignition Coil Removal/Instal-
lation).
Measure the primary winding resistance [A].
Connect an ohmmeter between the coil terminals.
Set the meter to the × 1 Ω range, and read the meter.
Measure the secondary winding resistance [B].
Remove the spark plug cap by turning it counterclock-
wise.
Connect an ohmmeter between the spark plug lead and
the green terminal (earth).
Set the meter to the × 1 kΩ range, and read the meter.
Ignition Coil Winding Resistance
Primary windings:
Secondary windings:
If the meter does not read as specified, replace the coil.
If the meter reads as specified, the ignition coil windings
are probably good. However, if the ignition system still
does not perform as it should after all other components
have been checked, test replace the coil with one known
to be good.
Check the spark plug lead for visible damage.
If the spark plug lead is damaged, replace the coil.

Spark Plug Cleaning and Inspection

Refer to the Spark Plug Cleaning and Inspection in the
Periodic Maintenance chapter.

Spark Plug Gap Inspection

Refer to the Spark Plug Cleaning and Inspection in the
Periodic Maintenance chapter.

Igniter Removal

Remove:
Seat (see Seat Removal in the Frame chapter)
Left Side Cover (see Side Cover Removal in the Frame
chapter)
Starter Relay
Remove the igniter [A], and disconnect the igniter con-
nectors [B].

Igniter Inspection

When inspecting the IC Igniter observe the follow-
ing to avoid damage to the IC Igniter.
Do not disconnect the IC Igniter while the engine is
running.
This may damage the IC Igniter.
0.19 ∼ 0.23 Ω at 20°C (68°F)
2.5 ∼ 3.7 kΩ at 20°C (68°F)
