Kawasaki WORKHORSE 250 (2003) [293/322] Commutator diameter

ELECTRICAL SYSTEM 16-37

Electric Starter System

•

Measure the diameter [A] of the commutator [B].

Replace the starter motor with a new one if the commu-

tator diameter is less than the service limit.

Commutator Diameter

Standard: 28 mm (1.10 in,)

Service Limit: 27 mm (1.06 in,)

Armature Inspection

•

Using the x 1 Ω range of the hand tester, measure the

resistance between any two commutator segments [A].

If there is a high resistance or no reading (∞) between

any two segments, a winding is open. Replace the starter

motor.

•

Using the highest range of the hand tester, measure the

resistance between the segments and the shaft [B].

If there is any reading at all, the armature has a short.

Replace the starter motor.

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.

Starter Motor Brush Length

•

Measure the overall length [A] of each brush.

Starter Motor Brush Length

Standard: 10 mm (0.39 in,)

Service Limit: 6.5 m m (0 .2 6 in,)

If any is worn down to the service limit, replace the brush

plate assembly.

Brush Assembly Inspection

•

Using the x 1 Ω range of the hand tester, measure the

resistance as shown.

[A] Terminal B olt and Positive Brush

[B] Brush Plate and Negative Brush

If there is not close to 0 Ω, the brush lead has an open.

Replace the brush plate assembly.
