Checking the traction relay
1. Remove the starter.
2. Remove the cover from the drive side and disconnect the traction relay.
3. Check the resistance between the terminals of the traction relay in two positions.

Stator check
1. Check for continuity between positive brushes "A" and terminal "M".
2. Make sure there is conductivity between the negative brushes "B" and the housing.

3. Check that there is no conductivity between the positive and negative brush and between the positive brush and the housing.
4. Measure the resistance between the brushes and the stator housing using a megohmmeter with a rated voltage of 500 V.
- Nominal resistance - above 0.01 MOhm
Checking the overrunning clutch
1. Pull out the overrunning clutch and make sure it moves freely. Replace the overrunning clutch if faulty.
2. Lock the gear and turn the overrunning clutch in the direction shown, make sure it rotates freely. Also make sure the clutch locks in the opposite direction, if the clutch does not lock, replace it.

3. Check the gear for wear and damage. If the gear is worn, replace the clutch assembly.
Check the condition of the torque converter ring gear. Replace it if the clutch gear teeth are damaged.
Checking the anchor
1. Check the anchor for damage and wear.

2. Measure the diameter of the collector. If it is less than the minimum, replace the anchor.
Collector diameter:
- nominal - 27.9 - 28.0 mm
- minimum - 27.0 mm

3. Install the anchor on the prisms and check the commutator runout. If the runout is greater than the maximum, replace the anchor.
Beating:
- nominal - 0.05 mm
- maximum - 0.40 mm

4. Check the surface of the commutator. If the surface is dirty or has traces of burning, re-sharpen it using sandpaper (#500, #600) or on a lathe.

5. Check the amount of protrusion of the collector lamellas. Use a hacksaw to cut grooves if necessary. Make sure the grooves are deep enough, not too narrow or V-shaped.
Lamel protrusion:
- nominal - 0.45-0.75 mm
- maximum - 0.20 mm

6. Check for conductivity between the collector lamellas. Replace the anchor if there is no conductivity.

7. Mount the anchor on the tester. Fix the hacksaw blade on the anchor core. If the blade is pulled to the center or vibration occurs when turning the core, the anchor is shorted. Replace it.

8. Make sure there is no conductivity between the commutator lamellas and the armature core, between the commutator lamellas and the armature shaft.

Checking the brushes
Check the length of brush "A". If the brush length is less than the minimum, replace it.
Brush length:
- Nominal length - 9.7-10.0mm
- Minimum length - 6.0 mm
