Warning: Perform this test for 3-5 seconds to avoid damaging the stator winding.
1. Checking the pull-in winding of the traction relay.
a) Disconnect the winding wire from the starter terminal "C".
b) Connect the wires from the battery to the terminals of the traction relay as shown in the figure. Make sure that the overrunning clutch gear has moved outward.
3C-T (starter 1.4 kW)
ZS T (starter 2.2 kW)
3S-FE, 4S-FE
If the overrunning clutch pinion does not extend, replace the traction relay assembly.
2. Checking the holding winding.
With the connection made as described in the previous step and the overrunning clutch pinion extended, disconnect the (-) wire from terminal "C". Make sure that the pinion remains extended.
If the pinion gear returns inward, replace the traction relay assembly.

3. Check if the core returns inside.
Disconnect the negative (-) cable from the traction switch housing. Make sure the pinion gear is retracted.
If the pinion gear does not retract, replace the traction relay assembly.

4. (ZS-T) Check that the starter is running without load.
a) Connect the wires from the battery and from the ammeter to the starter as shown in the figure, and also connect the winding wire to the starter terminal "C".
b) Check that the starter armature rotates evenly and the drive gear of the overrunning clutch is extended.
Measure the current using an ammeter.
Nominal current:
- starter 1.4 kW - no more than 90 A POI 11.5 V
- starters 2.0 and 2.2 kW - no more than 120 A at 11.5 V
ZS-T (starter 1.4 kW)
ZS-T (starter 2.2 kW)
