Check of system of a charging

If you found malfunction in charging system — malfunction of the generator cannot be the unique reason. Execute the following checks.

    Examine a driving belt and be convinced that it is tense and it is not damaged. At detection of damages replace it (address to Head the Current leaving and service). Be convinced of that bolts of fastening of the generator are reliably tightened. Check conducting of the generator and all sockets. All contacts should be reliable and not oxidized. Check the corresponding safety locks located in an impellent compartment (address to Head Onboard electric equipment). At detection burned down eliminate the reason of a peregoraniye of a safety lock and replace it (at a peregoraniye of the corresponding safety lock you cannot start the engine or include any of devices). Start the engine and be convinced that from the generator extraneous sounds (whistle or squeal are not distributed can signal about malfunction of bearings or wear of brushes). Be convinced of that the storage battery is completely charged. If one of a banok is damaged, the storage battery can consume a superfluous current. Disconnect tips of wires from the storage battery (at first negative). Examine plugs of the storage battery and tips of wires. At detection of traces of corrosion carefully clear them (address to materials of Head the Current leaving and service). Attach tips of wires to plugs and reliably tighten.
