1. Remember that violations of functioning of system of a charge are far not necessarily connected with failures of the generator. First of all always you make the following elementary checks:

a) Check a state and effort of a tension of a driving belt of the generator (see the Head Nastroyki and routine maintenance). In case of need make replacement;
b) Check reliability of tightening of fixing bolts of the generator;
c) Check a condition of an electrical wiring and electric connections of the generator;
d) At the corresponding complete set check a condition of the fusible insert established between the traction relay of a starter and the generator or a condition of big main safety locks in a motive compartment. In case of identification of the beaten-out elements, establish and eliminate the reason of the overloads taking place, then replace defective components;
e) Check a condition of all safety locks included in an electric chain of system of a charge. Location of safety locks and fusible inserts can vary depending on model and year of release of the car (see the Head Onboard electric equipment);
f) Start the engine and estimate intensity of the noise background published by the generator;
g) Check electrolyte density in banks of the rechargeable battery, in case of need make recharge of the last;
h) Make sure of completeness of a charge of the battery, - one faulty can can be the reason of a recharge of the battery);
i) Disconnect from the battery at first negative, then positive wires.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that you have the correct combination for input of the audio system in action! Estimate a condition of wires of the battery in places of their connection them to polar plugs of the last. Check reliability of fastening of terminal clips. Having carefully smoothed out contact plugs, connect the battery.

2. Execute checks of serviceability of functioning of the generator and the regulator of tension (see the Section Check of Serviceability of Functioning, removal and installation of the generator).
