Electric circuit of the generator



At the serviceable generator the signaling device of the category of the battery should light up at inclusion of ignition and die away after engine start-up. If the signaling device indicates abnormal operation of the generator or the storage battery is not charged, it is necessary to carry out malfunction diagnostics. It is necessary to mean also that often reason of the category of the battery is long work of consumers of the electric power at the switched-off engine. Malfunction of switches of lamps, for example, illumination of a luggage carrier or a perchatochny box can be one of the reasons of the category. In this case when closing covers of a lamp are not switched off, and remain included and discharge the battery.

1) Visually to check a condition of a belt and wires.

2) At the included ignition also I do not work the shchy engine a signaling device of the category should burn. If it does not burn, to disconnect electric wires from the generator and to connect the plug of a wire of L to "weight" through a lengthening wire with fusible предохра a nitel on 5 And.

2а. If the signaling device joined, to replace the generator.

2б. If the signaling device still does not burn, in a chain from the ignition lock to the plug of a wire there is a gap. Besides, probably peregorany lamps of a signaling device.

3) At the included ignition and the engine working at small speed the signaling device of the category should be switched off. If it burns, to disconnect electric wires from the generator.

3а. If the signaling device went out, it is necessary to replace the generator.

3б. If the signaling device continues to burn, in a chain from the wire plug to a lamp of a signaling device there is a short circuit on "weight".


Prevention

It is necessary to check operation of the generator according to item 4 before drawing a conclusion about refusal of a regulator of tension.


4) To check operation of the generator.
Prevention

For a correctness of check it is necessary, that the storage battery was completely charged.


4а. To collect the electric circuit shown on fig. An electric circuit for generator check on the car. To be convinced that the coal shunt is switched off.

4б. At the switched-off ignition to measure and write down tension of the battery.

4в. To remove plugs of wires from the generator.

4г. To include ignition (The engine should not work) and to measure by a digital tester tension on the L-wires plug. This tension should be approximately equal tension on battery conclusions. If tension on the plug L strongly differs from tension of the battery, it is necessary to check an electric chain from a signaling device to the plug L on gap or short circuit existence on "weight". To eliminate the found malfunctions.

4д. To connect wires to the generator.

4е. To start the Engine and to measure tension on battery conclusions at small speed of rotation of a cranked shaft. This tension should be higher than the tension measured in operation 4г, but should not exceed 16 Century. Otherwise it is necessary to replace the generator.

4ж. To measure a generator current at small speed of rotation of a cranked shaft of the engine idling. By means of adjustment of the coal shunt to achieve receiving the maximum current of the generator at tension on battery conclusions not less than 13 V.Esli the measured current differs from nominal rate no more, than on 15 And, the generator is serviceable. Otherwise it is necessary to replace the generator.

4з. On the generator working in the maximum mode to measure by the voltmeter tension between the case of the generator and a negative conclusion of the battery. Power failure should not exceed 0,5 V.Esli power failure exceeds 0,5 In, to check an electric chain between the case of the generator and the battery and to establish the reason. To clear and tighten connections of wires with "weight".
