Kawasaki VULCAN 2000 (2003) [521/633] Ignition coil winding resistance

Kawasaki VN2000 (2003) [521/633] Ignition coil winding resistance
ELECTRICAL SYSTEM 16-43
Ignition System
To determine which part is defective, measure the arcing
distance again with the spark plug caps removed from the
ignition coil. Remove the caps by turning them counter-
clockwise.
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 coil 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.
Measure the primary winding resistance as follows.
Connect the hand tester between the coil terminals.
Set the tester to the × 1 range, and read the tester.
Measure the secondary winding resistance as f ollows.
Remove the plug caps by turning them counterclockwise.
Connect the tester between the spark plug High-Tension
cables.
Set the tester to the × 1 k range and read the tester.
Measure primary winding resistance [A].
Measure secondary winding resistance [ B].
Ignition C oil [C]
Ignition Coil Winding Resistance
Primary Windings:
1.9 ~ 2.5
Secondary Windings: 10 ~ 1 6 k
If the tester does not read as specified, replace the coil.
To install the plug cap, turn it clockwise.
Spark Plug Removal
Remove:
Fuel Tank (for Rear Spark Plug, see Fuel System chap-
ter)
Spark Plug Caps [A]
Remove the spark plug using the 16 mm (0.63 in.) plug
wrench vertically.
Special Tool - Spark Plug Wrench, Hex16: 57001-1262
CAUTION
The insulator [A] of the spark plug may break if
when the wrench is inclined during loosening.
[B] Inclined Spark Plug Wrench
[C] Contact (Spark Plug and Plug Wrench)
[D] Bad
[E] Vertically Spark Plug Wrench
[F] Good
