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 ...

Piston Ring, Piston Ring Groove Wear Inspection
Check for uneven groove wear by inspecting the ring seating. The rings should fit perfectly parallel to groove surfaces. If not, replace the piston and all the piston rings. With the piston rings in their grooves, make several measurements with a thickness gauge [A] to determine pisto ...

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 ...

For Secondary Fuel Injectors
Remove the fuel tank (see Fuel Tank Removal). Disconnect the secondary fuel injector connector [A]. Connect a digitalmeter to the terminals in each secondary fuel injector [A]. Measure the secondary fuel injector resistance. Secondary Fuel Injector Resistance Standard: Abo ...
