|
For performance described below procedures the voltmeter and the ampermeter with a range of measurement 80-0-80 be required And. |
|
|
Watch polarity of connection of the battery (see size tables and adjustments at the end of the Management).
Do not short-circuit and do not earth the general with a charging contour of the plug.
Before connection of the charger disconnect the battery.
When using the auxiliary battery connect it in parallel, i.e. plus to plus, a minus to a minus that the general target tension remained equal 12 Century.
At all do not disconnect the battery or plugs of a charging contour at the working engine.
Regularly check a condition and effort of a tension of a driving belt (it).
Watch purity of plugs of the battery and reliability of fastening of all contact connections.
At performance of electrowelding works on the car without fail disconnect the battery and the generator.
|
|
Check on the car
|
|
If the control lamp of a charge remains included after start of the engine and installation of its turns on value 1 000 in a minute or if there are bases to suspect violation of level of a charge of the battery in this or that party, execute a series listed below checks. |
|
|

Connect a tachometer.
Include a driving beam of head headlights. Leave headlights included for the period of about five minutes for decrease in level of a charge of the battery and creation of load of a contour.
Start the engine and gradually lift its turns to value about 2 500 in a minute. The indication of the ampermeter should make about 75 % from nominal rate of this generator (see size tables and adjustments at the end of the Management).
Switch off all lighting devices and dump engine turns to 2 000 in a minute, achieving falling of instrument reading is lower than 10 A.Napryazheniye's level thus should to get to an interval from 14.1 to 14.7 Century.

Check of a condition and serviceability of functioning of components
|
|
Electric checks components should establish all subjects on dielectric supports. |
Rotor assembly with excitement windings
|
|
Check of short circuit of windings on weight is made by means of an ohmmeter. Connect one of measuring щупов the device to one of excitement windings / sliding rings, and the second - to one of polar tips of a rotor (see an accompanying illustration).
If conductivity takes place, and it is not possible to reveal and eliminate the visible reasons of short circuit, replace rotor assembly.
For check of resistance of windings of a rotor connect measuring щупы an ohmmeter to sliding rings (see an accompanying illustration). If conductivity is absent, replace a rotor.
Check of a stator is made by means of a sampler and ohmmeter lamp.
Wires of a stator are necessary for disconnecting from rectifier assembly.
Connect one of measuring щупов an ohmmeter to one of wires of the stator, the second щуп - to the second wire. Consider instrument reading.
Repeat measurement for the remained wires, we will check thereby all phases.
If between results of measurements there is a difference assembly of a stator it is necessary to replace.
Connect a wire crossing point between the negative plug of the charged 12-manumission of the battery and an obmotochny frame of a stator. Serially connect one of lamp sampler wires to all wires of a stator.
Inclusion of a paw of a sampler (soft luminescence) should be regarded as a sign of existence of short circuit. Assembly of a stator should be thus replaced.

|
|
Connect measuring щупы an ohmmeter between the case and one of contacts of diode assembly. Change a connection order щупов for return and make sure that conductivity takes place only in one direction.
Repeat check for all other contacts of assembly. If the condition of check is not carried out (conductivity on any of contacts takes place in both directions, or in general is absent), replace diode assembly.
|
|
Brushes and shchetochny springs
|
|
Check springs of brushes on existence of signs of an overheat and deformation. Check freedom of sliding of brushes in shchetkoderzhatel.
Measure length of brushes, compare result of measurements to requirements of size tables and adjustments, in case of need replace brushes.
