Tension regulator

The generator in the car can be compared to the bicycle generator: rather the generator rotates, the tension rises above and, therefore, the moving current grows. Consumers of current in the car long would not sustain such take-off and power failure therefore the special regulator has to limit tension of the generator and not allow an excessive battery charging. This regulator – the electronic regulator of tension – is screwed directly on the generator.
