Check of a condition of system of a charge

Function chart of standard system of a charge

1 — the ignition Switch
2 — the Main fusible insert
3 — the Control lamp of a charge
4 — a tension Regulator

5 — Statornaya a winding
6 — the Rotor winding
7 — the Battery
8 — the Generator


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

   a. Check a condition and effort of a tension of a driving belt of the generator (see. Head of Control and routine maintenance of the car). In case of need make replacement;
   b. Check reliability of a tightening of fixing bolts of the generator;
   c. Check a condition of electroconducting 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 an impellent compartment. In case of identification of the beaten-out elements, reveal and eliminate the reason of taking place overloads, then replace defective components;
   e. Check a condition of all safety locks included in an electric chain of system of a charge (address to an illustration above). Location of safety locks and fusible inserts can vary depending on model and year of release of the car, however the system of designations thus remains invariable. To check are subject: main fusible insert, fusible insert of ALT (80А), fusible insert of AM1 (40А), fusible insert of AM2 (30А), IG2 safety lock (7.5А), GAUGE safety lock (10А) and ALT safety lock (7.5A);
   f. Start the engine and estimate intensity of a noise background published by the generator;
   g. Check electrolit density in banks of the storage battery, in case of need make additional charge of the last;
   h. Make sure of completeness of a charge of the battery, – one faulty bank can be at the bottom of a battery recharge);
   i. Disconnect from the battery at first negative, then positive wires. 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. By means of the voltmeter measure the tension which is given out by the battery at the muffled engine, – the result of measurement should make about 12 Century.
3. Start the engine and repeat check: this time indications should make 13.5 – 15.1 Century.
4. Include head headlights, at regularly functioning system of a charge tension should fall at first, then be restored to former level.
5. If the size of measured tension considerably exceeds nominal rate, replace a tension regulator (see. Section Check of serviceability of functioning of a starter and start chain).
6. At excessively low indications make checks of a regulator of tension and the generator (see further).
7. Remove from the generator a back cover. Earth the plug F (address to an accompanying illustration), start the engine and measure tension of the battery. If the result of measurement exceeds admissible value, replace a regulator. At excessively low indications of the voltmeter drive away the car in a car-care center workshop for check of target parameters of the generator with use of the ampermeter.
8. In the presence of near at hand ampermeter check of target parameters of the generator can be made by own strengths of the motorist. Connect the ampermeter to system according to the scheme provided on an accompanying illustration.

Instead of the ampermeter it is possible to use also the inductive indicator of a current which always can be got rather cheap in shops of automobile accessories.

9. Lift engine turns to value 2000 in a minute and consider the ampermeter indication at the switched-off onboard consumers of the electric power, then include a driving beam and transfer the heater fan to the maximum high-speed mode. Compare results of measurements to requirements of Specifications.
10. At excessively low indications make regenerative repair, or generator replacement.
