Repair B3-B4/Passat B3-B4 Volkswagen Passat>> Electric equipment>> Generator>> Main malfunctions of the generator and ways of their elimination
At generator check, and also at operation of the car it is necessary to observe a number of simple rules not to put the generator out of action:
– do not allow operation of the generator with the disconnected storage battery;
– do not check the generator on "spark" as thus via diodes the considerable current proceeds, and they fail;
– do not check diodes tension more than 12 In or megommetry;
– at carrying out electrowelding works disconnect all wires from the generator and from the storage battery.
Check serviceability of knots and chains of electric equipment and eliminate malfunctions at the idle engine and the disconnected storage battery.
If at inclusion of ignition the control lamp of a battery charging, a probable cause in the following does not burn:
– wire break between the generator, the lock of ignition and a control lamp — is eliminated with tension check on a chain, beginning from the generator;
– the storage battery is discharged — check tension and if necessary charge the storage battery;
– the bulb fused — replace it;
– generator brushes leaky adjoin to contact rings — check length of brushes and freedom of their moving in the holder;
– the winding of excitement of the generator burned down — check operability of a rotor and diodes and at detection of defects replace faulty details.
If the control lamp of a battery charging does not die away at increase in frequency of rotation of the engine, a probable cause in the following:
– the tension regulator failed — replace it with the new;
– the wire between the generator and a control lamp has contact to "weight" — replace a plait of wires or in addition заизолируйте a wire.
