Note:
- Use thick lead wires for testing.
- Do not apply voltage for more than 5 seconds.
- Use a fully charged battery for testing.
1. Checking the retracting winding of the traction relay.
Connect the starter as shown in the illustration. Make sure the gear is out.
2. Checking the holding winding. With the connections made as described in the previous paragraph and the freewheel drive gear extended, disconnect the wire from the terminal "M". Make sure the pinion gear stays extended.
3. Check gear retraction. Disconnect the wire from the traction relay housing. Make sure the freewheel drive gear retracts quickly inward.
4. Checking the operation of the starter without load.
A) Place the starter in a vise and connect as shown in the figure.
b) Make sure that the speed and current correspond to the nominal ones.
- Rated current - less than 50 A
- Rated speed - above 6000 rpm
