Kawasaki Ninja Service Manual: Armature Inspection

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

Using the × 1 Ω hand tester range, measure the resistance between any two commutator segments [A].

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.

Using the highest hand tester range, measure the resistance between the segments and the shaft [B].

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.

Commutator Cleaning and Inspection

Clean the metallic debris off the between commutator segments [A]. NOTE Do not use emery or sand paper on the commutator. Check the commutator for damage or abnormal wear. Replace ...

Refer to the Relay Circuit Inspection in the Electrical System chapter. If the fuel pump relay is normal, check the wiring to the fuel pump relay (see Fuel Pump Relay Circuit). Special Tool - Hand Tester: 57001-1394 If the wiring is good, check the ECU for its ground and power supply (se ...

Coolant Level Inspection
Situate the motorcycle so that it is perpendicular to the ground. Check the coolant level through the coolant level gauge on the reserve tank located to the left of the engine. The coolant level should be between the “F” (Full) and “L” (Low) level lines. A. Reserve Ta ...
