ELECTRICAL 13.9 Starter Motor Static Testing + - (F) (Disconnect R/W Wire) 1. Remove starter motor and disassemble. (See page 9.14 for exploded view) Mark end covers and housing for proper reassembly. 2. Remove pinion retaining snap ring, spring and pinion gear. Care should be exercised when selecting an appropriate solvent. The brushes must slide freely in their holders. If the commutator needs cleaning, use only an electrical contact cleaner and/or a non-metallic grit sandpaper. Replace brush assembly when worn to 5/16″ (.8 cm) or less. Starter Housing and Field Coil Inspection 1. Using a digital multitester, measure resistance between starter input terminal and insulated brushes. The reading should be .3 ohms or less. 2. Measure resistance between insulated brushes and field coil housing. The reading should be infinite. Armature Testing 1. Using a digital multitester, measure resistance between each of the segments of the commutator. The reading should indicate .3 ohms or less. 2. Measure resistance between commutator and armature shaft. Reading should be infinity. coil laminates. Rotate armature 360°.
