Generator

Cause of defect

Elimination method

Tension in an onboard network of the car at the working engine is lower 13,4 In

Too many powerful consumers of the electric power are included, especially at low turns of the engine. Short circuit in consumers

Limit use of powerful consumers idling, do not connect additional consumers over admissible capacity of the generator, check windings of electric motors on absence of short circuit

Weakened a tension of a belt of a drive of the generator

Tighten a belt

Weakened fastening of wires on a conclusion «+» the generator, the safety block in a motor compartment

Smooth out the oxidized surfaces of contacts, tighten connections

The tension regulator is faulty

Replace a regulator

The chain of excitement of the generator (the generator gives out the put tension only on high turns at a small current of return) is faulty

Smooth out the oxidized contacts, press out plugs

Brushes (the generator gives out the put tension only on high turns at a small current of return) "hanged" or are worn-out. The length of brushes should be not less than 8 mm

Eliminate "lag" of brushes, at their wear replace a shchetkoderzhatel, clear contact rings

Diodes of the vypryamitelny block are damaged

Replace diodes or the vypryamitelny block

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

Solder conclusions, 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 of a winding of a stator the generator "howls")

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

Tension in an onboard network of the car is higher 14,7 In

The tension regulator is faulty

Replace a regulator

Generator noise

Generator bearings, wear of a seat under the bearing in a generator cover are damaged, worn-out. Noise remains at disconnection of wires from the generator, but disappears if to remove a belt of a drive of the generator

Replace bearings or the generator assembled

The rotor touches stator strips

Check palpation of a shaft of a rotor, wear of bearings, damage of a rotor, a stator and seats. Replace faulty knots and details 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 a stator or the generator assembled

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

Replace the vypryamitelny block of the generator
