Connection diagram for testing the starter on the stand
1 - starter; 2 - voltmeter with a scale limit of at least 15 V; 3 - 800 A rheostat; 4 – ammeter with shunt for 1000 A; 5 - switch; 6 - battery
To verify the efficiency of the starter, it is necessary to check its electrical and mechanical data on the stand.
Connecting wires to the current 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 from a fully charged 6ST-55 battery or from a special current source, the voltage drop characteristic of which under load corresponds to the voltage drop characteristic of the 6ST-55 battery.
The temperature of the starter during checks should be 25±5°C, and the brushes should be well ground to the collector.
