2.6.2. Generator

Cause of defect

Elimination method

The signaling device of a charge of the rechargeable battery lights up at the working engine

The generator belt is badly tense or torn off

Tighten a belt

The chain of excitement of the generator (it gives the put tension only on high turns at small current of return) is faulty, tension regulator (for check use two sources of a direct current of 12 and 15 V (see Electric equipment) is damaged or replace the regulator obviously serviceable)

Smooth out the oxidized contacts, press out plugs, replace the fused safety lock No. 10, the faulty regulator of tension

Brushes hanged or are worn out, contact rings are oxidized (the generator gives the put tension only on high turns at small current of return). Not less than 5 mm have to be Vystupaniye of brushes from the brush holder

Smooth out contact rings a small glass skin, check lack of a beating. Eliminate lag of brushes, at their wear replace the brush holder

Tap of conclusions of a winding of excitement from contact rings, short circuit or break in a winding

Solder conclusions or replace a rotor of the generator or the generator assembled

Break or short circuit in a stator winding, its short circuit on "weight" (at short circuit the generator "howls")

Check an ohmmeter a winding. Replace the stator or the generator assembled

Short circuit of one or several positive gates

Replace a radiator with positive gates

Break in one or several gates

Replace a radiator with positive gates, to a perepressuyta negative gates or replace a back cover of the generator

Break between the plug "85" of the generator and the center of a star of windings of the stator (it is checked by an ohmmeter)

Restore connection

The charge signaling device relay is faulty (see Electric equipment)

Replace the relay

The signaling device of a charge does not light up, but the rechargeable battery is charged badly (hardly scrolls the engine at start-up). Tension in onboard network lower than 13,6 In (it is checked by an autotester)

The generator belt is badly tense

Tighten a belt

Too many powerful consumers of the electric power are included, especially at low turns of the engine. Short circuit in consumers (usually it is windings of electric motors)

Limit use of powerful consumers idling, do not connect additional consumers over the admissible power of the generator, check windings of electric motors for lack of short circuit

The chain of excitement of the generator, tension regulator are faulty

Smooth out the oxidized contacts, press out plugs, replace the faulty regulator of tension

Brushes hanged or are worn out, contact rings are oxidized (the generator gives the put tension only on high turns at small current of return). Not less than 5 mm have to be Vystupaniye of brushes from the brush holder

Smooth out contact rings a glass skin, check lack of a beating. Eliminate lag of brushes, at their wear replace the brush holder

Tap of conclusions of a winding of excitement from contact rings, short circuit or break in a winding

Solder conclusions or replace a rotor of the generator or the generator assembled

Fastening weakened or tips of wires on a conclusion "+" the generator, the rechargeable battery, the plug in a splitter are oxidized (on the right mudguard in a motor compartment)

Smooth out plugs and tips, tighten connections

Break or short circuit in a stator winding, its short circuit on "weight" (at short circuit the generator "howls")

Check an ohmmeter a winding. Replace the stator or the generator assembled

Diodes of the vypryamitelny block are damaged

Replace diodes or the vypryamitelny block

The rechargeable battery is recharged (electrolyte level quickly goes down). Tension in onboard network of the car higher than 14,7 In (it is checked by an autotester)

Tension regulator is faulty

Replace the regulator

Short circuit between the screw of fastening of the brush holder and the tire of the brush attached to conclusion "Ш" of the regulator (G-221)

Eliminate short circuit or replace the plastic basis of the brush holder

The signaling device of a charge of the rechargeable battery does not light up at inclusion of ignition

The lamp fused

Replace a lamp

Contacts of the holder of a lamp departed or were oxidized

Smooth out, press out contacts

The charge signaling device relay is faulty (see Electric equipment)

Replace the relay

Short circuit in one or several negative gates

Negative gates or replace with Perepressuyte a back cover of the generator

Short circuit of a winding of the stator on "weight" (the generator "howls")
Break of a chain between the plug "87" of a signaling device of a charge and the block of safety locks

Check an ohmmeter a winding. Replace the stator or the generator assembled
Restore connection

Noise of the generator

Generator bearings (squeal, howl), wear of a seat in a generator cover are damaged. (Noise remains at disconnection of wires from the generator, but disappears if to take off a belt)

Replace bearings, a cover or the generator assembled

The rotor touches stator poles

Check a rotor shaft beating, wear of bearings and seats. Replace defective parts or the generator assembled

Short circuit in a stator winding, its short circuit on "weight" (the generator "howls"). Noise disappears if to disconnect wires from the generator

Replace the stator or the generator assembled

Short circuit in one of the main gates. Noise disappears if to disconnect wires from the generator

Replace a radiator with positive gates, to a perepressuyta negative gates or replace a back cover of the generator
