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.

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.
