The basic electric scheme of the generator


 At generator service observe the general rules of precaution at works with electric devices!


For a complete set of considered models generators of an alternating current, company Mitsubishi manufacture are used. On type the given generators concern to three-phase with the built in rectifier. The design and the basic electric scheme of the generator are presented on illustrations. Alternating current straightening is carried out by means of диодной the assemblage consisting of three positive and three negative diodes. The control of target pressure of the generator carries out the built in regulator which also carries out diagnostics functions.

Continuous switching of a field winding of the generator by the special transistor provides a constancy of level of target pressure.

For the control of serviceability of functioning of the generator the control lamp which is a part of a combination of devices of the car is included in a chain of system of a charge. Number of the most typical refusals causing operation of a control lamp concern:

a) the Generator has ceased to give out pressure owing to deterioration of brushes, breakage of a field winding, etc.;
b) pressure Given out by the generator exceeds 16В;
c) there Was a detachment of electroconducting from the plug In the generator;
d) there Was a detachment of electroconducting from generator plug S, - in the present state of affairs the generator will be given out by slightly raised pressure, however the battery remains protected from a recharge at the expense of serviceable functioning of a regulator of pressure.

 PERFORMANCE ORDER

 Use in the given check of the diagnostic devices calculated on measurement of a high voltage is fraught with a rectifier exit out of operation!

1. For check диодной assemblages remove it from a back cover of the generator and serially check up an ohmmeter conductivity of each of three diodes, - conductivity should take place only in one direction.
2. Make sure available conductivity between a conclusion of the positive diode and a radiator located from a positive side of assemblage of the rectifier. It is possible to consider the diode serviceable if resistance less than 1 Ohm is present only at a direction from a conclusion to a radiator.
3. Check of negative diodes is made in return polarity.
4. If any of diodes passes a current in both directions, or does not pass it at all, all диодная assemblage is subject to replacement.


Anchor

 PERFORMANCE ORDER

1. Attentively examine a working surface of a contact ring on presence having chopped off, roughnesses, задиров and traces подгорания. Insignificant defects can be eliminated by processing of a surface by a fine-grained emery paper, or or протчкой it on a lathe. At revealing of ineradicable defects the ring/anchor is subject to replacement.
2. By means of a calliper measure diameter of a contact ring. If the ring is worn out over an admissible limit (less than 22.1 mm), replace anchor assemblage.

3. Measure resistance between contact rings of anchor assemblage, - demanded value makes 2.7 3.2 Ohm. At appreciable deviations of resistance from rating value anchor assemblage is subject to replacement.

4. For an estimation of quality of isolation check up assemblage on conductivity presence between each of contact rings and the anchor core/shaft. Conductivity presence (the indication of an ohmmeter less than 1 Ohm) testifies to short circuit formation in a winding of an anchor and-or on a contact ring. The faulty anchor is subject to replacement.


Статор

 PERFORMANCE ORDER

1. Make sure available conductivity between conclusions of windings статора.

2. For an estimation of quality of isolation check up статор on conductivity presence between windings and the core.

3. In case of revealing of signs of short circuit or breakage in windings статор is subject to replacement.


Brushes

 PERFORMANCE ORDER

1. Brushes are subject to replacement at deterioration till the length less than 5 mm. Degree of deterioration of a brush can be defined also by means of a special service label (A). For extraction of a brush from the holder it is necessary отпаять the electroconducting built in in it from the contact plug.

2. Fill a brush in the holder so that its end acted on 2 mm and measure effort of compression щеточной springs, - if the result of measurement makes less than 2.65 Н, the spring is subject to replacement.

 The effort of compression of a new spring equals 4.6 5.8 Н.


Bearings

 PERFORMANCE ORDER

1. Manually estimate smoothness of rotation of bearings. In case of need make replacement.
2. The back bearing is taken by means of a usual stripper.
3. For replacement of the forward bearing remove its holder, establish on an internal holder approaching оправку, then squeeze out the bearing by means of a press or a vice. Establish the new bearing in an order, the return to removal.
