DSG-423 STARTER
07-5
DIAGNOSIS AND TESTING
WARNING: REFER TO CAUTIONS & WARNINGS AT
THE BEGINNING OF THIS SECTION.
NOTE: When testing with a meter, always make
connections with the component terminal rather than at
the wiring end connector. Making connection with the
wiring end connector can result in a false reading,
because the meter will not pick up any high resistance
between the wiring connector and the component.
Visual Inspection
CAUTION: Be sure to disconnect battery negative
cable before servicing starter.
• Verify the concern by operating the starting system
to duplicate the conditions.
• Inspect starting system for loose connections.
• Check the wear patterns on the starter drive and the
flywheel ring gear. If the starter drive gear and the
flywheel ring gear are not fully meshing or the gears
are milled or damaged, replace the starter motor and
if necessary, replace flywheel ring gear.
If the inspection reveals an obvious concern that can be
readily identified, repair as necessary.
If the concern remains after the inspection, note
condition and continue diagnosis using the symptom
chart.
