Kawasaki Ninja Service Manual: Crankshaft Sensor Peak Voltage Inspection

Kawasaki Ninja Service Manual / Electrical System / Ignition System / Crankshaft Sensor Peak Voltage Inspection

NOTE

Be sure the battery is fully charged.
Using the peak voltage adapter [A] is more reliable way to determine the condition of the crankshaft sensor than crankshaft sensor internal resistance measurements.

Crankshaft Sensor Peak Voltage Inspection

Disconnect the crankshaft sensor lead connector (see Crankshaft Sensor Removal).
Set the hand tester [B] to the DC 10 V range, and connect it peak voltage adapter.

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

Connect the adapter to the terminals of the crankshaft sensor lead connector [C].

Connections: Crankshaft Sensor Lead Connector Peak Voltage Adapter Hand Tester Y lead ← R lead → (+) BK lead ← BK lead → (–)

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 peak voltage.
Repeat the measurements 5 times or more times.

Crankshaft Sensor Peak Voltage Standard: 1.9 V or more

If the reading is less than the standard, inspect the crankshaft sensor (see Crankshaft Sensor Inspection).
