The operation of a working generator after starting the engine is to provide all consumers included in the on-board network of the machine with an electric current of the required strength and voltage. But the rotating rotor of the generator is not a guarantee that the energy it generates meets the required parameters.
Necessary
Voltmeter
Instructions
Step 1
To make sure that the generator copes with the responsibilities assigned to it, it is tested with a voltmeter. The voltage is measured according to the following scheme: - The hood is lifted;
- The terminal “+” of the voltmeter is connected to the terminal “30” of the generator;
- The "-" clamp of the voltmeter is connected to the battery terminal of the same name.
Step 2
After that, the engine is started and its speed is brought to 3000 rpm. In this case, the generator must generate a voltage not exceeding 14.4 volts, which remains within the same limits after connecting powerful consumers (high beam headlights, bass amplifier, subwoofer, etc.).
Step 3
If non-compliance with regulatory requirements is observed, then it is necessary to check the following: - Tension of the alternator drive belt;
- The condition of the wiring terminals (for the reliability of their fastening and oxidation);
- Condition of brushes and copper slip ring of the generator;
- The state of charge of the battery.
Step 4
And in cases where no violations have been identified, the generator is dismantled from the engine and undergoes refurbishment.
