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.
