InspectionEKS0031L
MAGNETIC SWITCH CHECK

Before starting to check, disconnect the battery cable from the negative terminal.

Disconnect “M” terminal of starter motor.
1. Continuity test (between “S” terminal and switch body).

No continuity... Replace.
2. Continuity test (between “S” terminal and “M” terminal).

No continuity... Replace.
PINION/CLUTCH CHECK
1. Inspect pinion teeth.

Replace pinion if teeth are worn or damaged. (Also check
condition of ring gear teeth.)
2. Inspect reduction gear teeth (If equipped).

Replace reduction gear if teeth are worn or damaged. (Also
check condition of armature shaft gear teeth.)
3. Check to see if pinion locks in one direction and rotates
smoothly in the opposite direction.

If it locks or rotates in both directions, or unusual resistance is
evident.... Replace.
BRUSH CHECK
Brush
Check wear of brush.

Excessive wear... Replace.

Not within the specified values... Replace.
Brush Holder
1. Perform insulation test between brush holder (positive side) and
its base (negative side).

Continuity exists.... Replace.
2. Check brush to see if it moves smoothly.

If brush holder is bent, replace it; if sliding surface is dirty,
clean.
