Wiring diagram for testing the starter on the stand
1 – starter; 2 – voltmeter with a scale limit of at least 15 V; 3 – rheostat 800 A; 4 – ammeter with 1000 A shunt; 5 – switch; 6 – battery
To ensure the efficiency of the starter, it is necessary to test its electrical and mechanical data on a bench.
The connecting wires to the power source, ammeter and contact bolt of the starter traction relay must have a cross-section of at least 16 mm².
The starter must be powered by a fully charged 6ST-55 battery or by a special current source whose voltage drop characteristic under load corresponds to the voltage drop characteristic of the 6ST-55 battery.
The starter temperature during testing should be 25±5°C, and the brushes should be well ground to the commutator.
