Kawasaki Ninja Service Manual: Stick Coil Primary Peak Voltage Inspection

Kawasaki Ninja Service Manual / Electrical System / Ignition System / Stick Coil Primary Peak Voltage Inspection

NOTE

Be sure the battery is fully charged.

Remove the stick coils (see Stick Coil Removal).

Do not remove the spark plugs.

Connect the ECU to the harness.
Measure the primary peak voltage as follows.

Stick Coil Primary Peak Voltage Inspection

Install the new spark plug [A] into each stick coil [B], and ground them onto the engine.

Connect the peak voltage adapter [C] into the hand tester [D] which is set to the DC 250 V range.

Connect the adapter to the lead wire-peak voltage adapter [E] which is connected between the stick coil connector and stick coil.

Stick Coil Primary Peak Voltage Inspection

Connections: Adapter (R, +) → Lead Wire-Peak Voltage Adapter (W) Adapter (BK, –) → Lead Wire-Peak Voltage Adapter (R)

WARNING

To avoid extremely high voltage shocks, do not touch the spark plugs or tester connections.

Turn the engine stop switch to run position.
Turn the ignition switch to ON.
Pushing the starter button, turn the engine 4 ∼ 5 seconds with the transmission in neutral to measure the primary peak voltage.
Repeat the measurements 5 times for one stick coil.

Stick Coil Primary Peak Voltage Standard: 100 V or more

Repeat the test for the other stick coils.

If the reading is less than the specified value, check the following.

Spark Plug Removal

Refer to the Spark Plug Replacement in the Periodic Maintenance chapter.

Spark Plug Installation

Refer to the Spark Plug Replacement in the Periodic Maintenance chapter.

Stick Coil Inspection

Remove the stick coils (see Stick Coil Removal). Measure the primary winding resistance [A] as follows. Connect the hand tester between the coil terminals. Set the tester to the × 1 ...

Spark Plug Condition Inspection

Remove the spark plugs (see Spark Plug Replacement in the Periodic Maintenance chapter). Visually inspect the spark plugs. If the spark plug center electrode [A] and/or side electrode [B] a ...

Coupling Bearing Inspection
Since the coupling bearing is made to extremely close tolerances, the clearance can not normally be measured. NOTE It is not necessary to remove the coupling bearing for inspection. If the bearing is removed, it will need to be replaced with a new one. Turn the bearing in the coupling b ...

ECU Removal
NOTICE Never drop the ECU especially on a hard surface. Such a shock to the ECU can damage it. Remove the upper air cleaner housing (see Air Cleaner Element Replacement in the Periodic Maintenance chapter). Lift up the ECU [A] with rubber protector [B] to disconnect the connectors [C]. ...

Starter Motor Disassembly
Remove the starter motor (see Starter Motor Removal). Take off the starter motor through bolts [A] and remove the both end covers [B]. Pull out the armature [A] out of the yoke [B]. NOTE Do not remove the circlip [C] from the shaft. Remove the starter motor terminal lock ...
