Ignition Coil Primary Peak Voltage Inspection

• Remove:

Side Covers (see Side Cover Removal in the Frame

chapter)

Lower Fairings (see Lower Fairing Removal in the Frame

chapter)

• Remove the spark plug caps from the spark plugs.

• Attach a good spark plugs to the removed spark plug caps and ground them to the engine.

NOTE

О To obtain a correct measurement, the wires as well as the wire connections must be correct. Take the volt­age measurement with the proper cylinder compres­sion (with the spark plugs in the cylinder head). Without proper compression, a correct measurement cannot be obtained.

Ignition System

• Set the tester to the DC 250 V range. Connect the peak voltage adapter [B] to the tester [A], and connect the adapter terminals to the respective terminals of the ignition coil [C].

○Keep the terminals connected.

Special Tool - Kawasaki Hand Tester: 57001-1394 Peak Voltage Adapter: 57001-1415 Type: KEK-54-9-B

Connect #1

Adapter’s positive (+) → terminal black wire

terminal [D]

Adapter’s negative (–) → red wire terminal [E] terminal

#2

Adapter’s positive (+) → green wire terminal terminal

Adapter’s negative (–) → red wire terminal terminal

• _{Turn the ignition switch ON.}

• Shift the gears to neutral, and run the engine stop switch.

• Turn the starter motor for several seconds and read the maximum value on the tester.

Ignition Coil Primary Peak Voltage Standard: dc100 V or more

WARNING

To avoid high-voltage electrical shocks, do not touch the adapter terminals or leads.

• If the peak voltage is lower than the standard, refer to the next page.

Crankshaft Sensor Peak Voltage Inspection

• Measure the peak voltage of the crankshaft sensor as

follows: ○Remove the left side cover. ○Remove the crankshaft sensor connector [A].

NOTE

○To obtain a correct measurement, the wires as well as the wire connections must be correct. Take the volt­age measurement with the proper cylinder compres­sion (with the spark plugs in the cylinder head). Without proper compression, a correct measurement cannot be obtained.

○Set the tester to the DC10 V range.

○Connect the peak voltage adapter [A] to the tester, and

connect the adapter terminal to the crankshaft sensor

connector [B] terminal.

Connect

Adapter’s positive (+) terminal → yellow wire terminal

Adapter’s negative (–) terminal → black wire terminal

OTurn the starter motor for several seconds and read the maximum value on the tester.

Crankshaft Sensor Peak Voltage Standard: DC 3 V or more

• If the peak voltage is lower than the standard, inspect the crankshaft sensor.

Diodes Inspection

• Remove:

Lower Right Fairing (see Lower Fairing Removal in the Frame chapter)

• Disconnect the diode assembly [A].

• Zero the hand tester, and connect it to the diode terminal to check the resistance in both directions.

•The resistance should be low in one direction and more than ten times as much in the other direction. If any diode shows low or high in both directions, the diode is defective and the diode assembly must be replaced.
