The electric scheme for generator check on the car
The electric scheme of the generator
At the serviceable generator the signalling device of the category of the battery should light up at inclusion of ignition and die away after engine start-up. If the signalling device specifies in abnormal work of the generator or the storage battery is not charged, it is necessary to carry out malfunction diagnostics. It is necessary to have also in view of that more 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 перчаточного a box can be one of the category reasons. In this case at closing of covers of a lamp are not switched off, and remain included and discharge the battery.
1) Visually to check up a condition of a belt and wires.
2) At the included ignition and неработаю щем the engine the category signalling device should burn. If it does not burn, to disconnect electric wires from the generator and to connect the plug of wire L to "weight" through a lengthening wire with fusible предохра нителем on 5 And.
2а. If the signalling device has joined, to replace the generator.
2б. If the signalling device still does not burn, in a chain from the lock of ignition to the wire plug there is a rupture. Besides, it is possible blowing signalling device lamps.
3) At the included ignition and the engine working on small speed the category signalling device should be switched off. If it burns, to disconnect electric wires from the generator.
3а. If the signalling device has gone out, it is necessary to replace the generator.
3б. If the signalling device continues to burn, in a chain from the plug of a wire to a signalling device lamp there is a short circuit on "weight".
It is necessary to check up generator work according to item 4 before doing a conclusion about refusal of a regulator of pressure.
4) to Check up generator work.
For a check correctness it is necessary, that the storage battery has been completely charged.
4а. To collect the electric scheme shown on fig. the Electric scheme for check of the generator on the car. To be convinced that the coal shunt is switched off.
4б. At the switched off ignition to measure and write down pressure 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 pressure on the L-wire plug. This pressure should be approximately equal pressure on battery conclusions. If pressure on plug L strongly differs from pressure of the battery, it is necessary to check up an electric chain from a signalling device to plug L on presence of rupture or short circuit on "weight". To eliminate the found out malfunctions.
4д. To connect wires to the generator.
4е. To start the Engine and to measure pressure on battery conclusions at small speed of rotation of a cranked shaft. This pressure should be above the pressure measured in operation 4г, but to exceed 16 Century Otherwise it should not is necessary to replace the generator.
4ж. To measure a generator current strength at small speed of rotation of a cranked shaft of the engine idling. By means of adjustment of the coal shunt to achieve reception of the maximum current of the generator at pressure on conclusions of the battery not less than 13 V.Esli the measured current strength differs from rating value 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 pressure between the case of the generator and a negative conclusion of the battery. The power failure should not exceed 0,5 V.Esli a power failure exceeds 0,5 In, to check up 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".
