Note: Run this test for 3-5 seconds to avoid damage to the stator winding.
1. Checking the retracting winding of the traction relay.
A) Disconnect winding wire from starter terminal "WITH".
b) Connect the wires from the battery to the terminals of the traction relay, as shown in the figure. Make sure the freewheel gear is out.
0.8 kW (series A)
1.2 kW (A series, S series)
1.4 kW (2C)
2.2 kW (2C)
If the freewheel drive gear does not advance, replace the traction relay assembly.
2. Checking the holding winding. With the connection made as in the previous paragraph and the overrunning clutch drive gear extended, disconnect (-) wire from outlet "WITH". Make sure the pinion gear stays extended. If the drive gear returns inside, then replace the traction relay assembly.
3. Check if the freewheel drive gear returns. Disconnect (-) wire from the traction relay housing. Make sure the freewheel drive gear is retracted inward. If the freewheel drive gear has not retracted, replace the traction relay assembly.
4. Check starter operation 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 "WITH".
0.8 kW (series A)
1.2 kW (A series, S series)
2.2 kW (2C)
1.4 kW (2C)
b) Check that the starter armature rotates evenly and the freewheel drive gear is extended. Measure the current with an ammeter.
Rated current (at 11.5 V):
- except starter 2.2 kW - 90 A
- starter 2.2 kW (2C) - 120 A
