ELECTRICAL SYSTEM 15-17
Pickup Coil Resistance (x 100 0)
355 - 5350 (BK, Y lead)
• Using the highest resistance range of the ohmmeter,
measure the resistance between the pickup coil leads
and chassis ground.
* Any meter reading less than infinity (00) indicates a
short, necessitating replacement of the pickup coil
assembly.

*If the distance reading is less than the specified value,
the ignition coil or spark plug caps are defective.
Ignition Coil Arcing Distance
7 mm or more
Ignition Coil Removal
• Remove surge tank cover (see Fuel System chapter)
• Remove the ignition coil from the bracket.
.To determine which part is defective, measure the arcing
distance again with the spark plug caps removed from
the ignition coil.
*If the arcing distance is subnormal as before, the trouble
is with the ignition coil itself. If the arcing distance is
now normal, the trouble is with the spark plug caps.
Ignition Coil Installation
.Connect the primary leads to the ignition coil terminals.

Ignition Coil Inspection
• Remove the ignition coils.
• Measure the arcing distance with Kawasaki coil tester
(special tool:
57001 -1242
to check the condition of
the ignition coil.
NOTE
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.
• Disconnect the primary leads from the coil terminals.
• Measure the primary winding resistance.
o
Connect an ohmmeter between the coil terminals.
o
Set the meter to the x 1 0 range, and read the meter.
• Measure the secondary winding resistance.
o
Pull the spark plug cap off the lead.
o
Connect an ohmmeter between the spark plug leads.
o
Set the meter to the x 1 kO, and read the meter.
* If the meter does not read as specified, replace the coil.
OSince a tester other than the Kawasaki coil tester may
produce a different arcing distance, the Kawasaki coil
tester is recommended for reliable results.

* 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
