Abstract

The invention discloses a detection testing circuit for a generator and an adjustor of an automobile. The circuit comprises a storage battery, a current meter, a first switch, a first voltage meter, a second switch, a generator, a first automobile headlamp, a second automobile headlamp, the adjustor, a second voltage meter and a relay. The detection testing circuit uses the automobile headlamps as load, and a frequency converting motor is used for driving the generator to work. Faults of the generator and the adjustor of the automobile can be detected fast and correctly through an armature circuit voltage meter, a generator excitation circuit voltage meter and a current meter connected with a positive pole of the storage battery. Simultaneously, the detection testing circuit has the advantages of being simple in structure, convenient to operate and low in cost.

Description

technical field [0001] The invention relates to a detection test circuit for an automobile generator and a regulator. Background technique [0002] The car charging system is mainly composed of a generator and a regulator. As the main power source in the operation of the car, the generator is responsible for supplying power to all electrical equipment except the starting system and charging the battery. Since the generator is driven by the engine to rotate through the transmission belt, when the engine speed changes, the output voltage of the generator changes; in order to meet the requirements of a certain range of voltage for automobile electrical equipment and charging the battery, a voltage regulator is installed in the charging system , by adjusting the excitation current of the generator, the generator can output a voltage in a stable range when the speed and load change. [0003] The common faults of the car charging system include three situations: no charging, too...
