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.

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

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.
