Kawasaki WORKHORSE 250 (2003) [283/322] Ignition coil arcing distance

ELECTRICAL SYSTEM 16-27

Ignition System

Ignition Coil Installation

•

Connect the primary winding leads to the ignition coil ter-

minals as shown.

G/W Lead ⇒ (+) Mark [A]

BK/Y Lead ⇒ (−)Mark

Ignition Coil Inspection

•

Remove the ignition coil.

•

Measure the arcing distance with a coil tester [A] to check

the condition of the ignition coil [B].

•

Connect the ignition coil (with the spark plug cap left at-

tached at the end of the spark plug lead) to the tester in

the manner prescribed by the manufacturer and measure

the arcing distance.

Ignition Coil Arcing Distance

7 m m (0.28 in,) or more

WARNING

To avoid extremely high voltage shocks, do not

touch the ignition coil body or leads.

If the distance reading is less than the specified value, the

ignition coil or spark plug cap is defective.

•

To determine which part is defective, measure the arcing

distance again with the spark plug cap removed from the

ignition coil lead.

○

Remove the cap by turning it counterclockwise.

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 cap.

If the coil tester is not available, the c oil can be checked

for a broken or badly shorted winding with the hand tester.

Special Tool - Hand Tester : 57001-1394

NOTE

○

The hand tester cannot detect layer shorts and shorts

resulting from insulation breakdown under high voltage.
