Kawasaki Ninja Service Manual: Armature Inspection

Kawasaki Ninja Service Manual / Electrical System / Electric Starter System / Armature Inspection

Special Tool - Hand Tester: 57001-1394

If there is a high resistance or no reading (∞) between any two segments, a winding is open and the starter motor must be replaced.

If there is any reading at all, the armature has a short and the starter motor must be replaced.

Armature Inspection


NOTE

Even if the foregoing checks show the armature to be good, it may be defective in some manner not readily detectable with the hand tester. If all other starter motor and starter motor circuit components check good, but the starter motor still does not turn over or only turns over weakly, replace the starter motor with a new one.

Braking
Close the throttle completely, leaving the clutch engaged (except when shifting gears) so that the engine will help slow down the motorcycle. Shift down one gear at a time so that you are in 1st gear when you come to a complete stop. When stopping, always apply both brakes at the ...

System Components
1. FI ECU The FI ECU analyzes the motorcycle conditions based on the signals from the front/rear wheel rotation sensors and FI sensors (such as the crankshaft sensor and main throttle sensor), and controls engine power by reducing the number of ignition and retarding the ignition timing. The m ...

Water Temperature Sensor Inspection
Remove the water temperature sensor (see Water Temperature Sensor Removal/Installation in the Fuel System (DFI) chapter). Suspend the sensor [A] in a container of coolant so that the temperature-sensing projection [C] is submerged. Suspend an accurate thermometer [B] with temperature ...
