Kawasaki Ninja Service Manual: 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.

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.

ECU [F] Battery [G]

Special Tools - Hand Tester: 57001-1394 Peak Voltage Adapter: 57001-1415 Type: KEK-54-9-B Lead Wire-Peak Voltage Adapter: 57001 -1449

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

• 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.
