The system of a charge consists of the generator of the alternating current which is built in the generator of the regulator of tension, a chain of a control lamp of a charge, the battery, a fusible crossing point and connecting wires (see rice. Scheme of a chain of a charge of the battery). At collaboration of these devices food of such consumers as system of ignition, devices of lighting and the alarm system, the radio receiver, etc. is provided. The drive of the generator is carried out from a belt in forward part of the engine.
The cars considered in the present manual are completed with generators of Nippondenso and Delco firms manufacturers.
The regulator of tension is intended for maintenance of tension of the generator at the set level. At sharp increase of tension at the generator exit the regulator prevents throws of current and an overload in a power-supply circuit.
The fusible crossing point represents a separate piece of a wire which is included consistently with a bunch of connecting wires from the battery and is bred in a motor compartment (see rice. Standard arrangement of a fusible crossing point of inserts). Along with the main crossing point of a charge are a part of the system additional fusible inserts which represent wire pieces with strictly set area of cross section. The area of section of inserts is less than at wires of that chain which is protected by this insert. More detailed information on fusible inserts is provided in subsection 12.2.
Periodic care of system of a charge as a rule it is not required. However, it is necessary to examine periodically a generator drive belt, the battery and connecting wires (inspection is performed with frequency through each 12000 km or 6 months).
The control lamp of a charge on the dashboard lights up at inclusion of ignition and after start-up of the engine dies away. If the lamp does not die away after start-up of the engine, in a chain of a charge is faulty. Some cars are equipped with the voltmeter. If the voltmeter shows very high or very low voltage, the chain of a charge needs check (see subsection 3.3.4).
Prevention
At connections of wires of an internal chain of the car and external devices it is necessary to observe the following precautionary measures:
– at connection of the battery with the generator always observe polarity of connection;
– before repair of any site of the car electric welding disconnect wires from the generator and from a battery conclusion;
– is inadmissible to start the engine at the connected charger;
– before connection of the charger always disconnect car chain cables from both poles of the battery;
– be careful of hit under a generator belt on the working engine of hands, hair, edges of clothes;
– the generator is attached directly to the battery therefore at a zakorachivaniye of conclusions of the generator, or at its overload, formation of an arch and the fire is possible;
– before washing of the engine with a vapor jet cover the generator a polyethylene film and fix a film a rubber bandage.
Check
| PERFORMANCE ORDER |
| 1. Check a state and a tension of a belt of the generator. At detection of signs of wear replace a belt. |
| 2. Check an inhaling of bolts of fastening of the generator and an adjusting bolt of a tension of a belt. |
| 3. Check conducting of the generator and regulator of tension, reliability of fastening and a condition of sockets. |
| 4. Check a fusible crossing point which is connected to a positive pole of the battery, and the fusible crossing points located in a motor compartment. At detection of the fused inserts find out the reason and eliminate, replace fusible inserts (at burn-out of inserts the engine will not be started, devices of electric equipment of the car will also not work). |
| 5. Check a condition of all fusible inserts which are included in a battery charge chain (see rice. Standard arrangement of a fusible crossing point of inserts). The place of installation of inserts depends on a year of release of the car, however, all inserts have identical designations. The main fusible crossing point – 3,0W, inserts: Alt H (80-100 A), AM1 (40 A), AM2 (30 A), IG (10 A), Gauge (10 A) and ALT-S (7,5 A). |
| 6. Start the engine and check the sound made by the generator (howling or squealing a sound points to wear of bearings). |
| 7. Check electrolyte density in the battery. If density low, charge the battery (this point does not belong to unattended batteries). |
| 8. Check completeness of a charge of the battery (at faulty section of the battery its recharge is possible). |
| 9. Disconnect cables from the battery (at first from a negative pole, then from positive). |
Prevention
Before a detachment of cables be convinced that to you the code of a raskodirovka of the radio tape recorder is known (if the last is equipped with the blocking device in case of plunder). Check a condition of poles of the battery and terminal tips of cables. If necessary clear plugs and poles. Attach a cable to a positive pole of the battery, then to the negative.
|
| 10. Check tension on the battery on the idle engine. Tension has to be about 12 Century. |
| 11. Start the engine and again check tension which has to be from 13,5 to 15, 1 Century now. |
| 12. Turn on a driving beam of headlights. During the normal work of system of a charge tension has to fall and again increase. |
| 13. If tension is higher than the normal tension of a charge, replace tension regulator. |
| 14. If tension is lower normal, check the regulator and the generator, having arrived as follows. |
|
15. Remove a back cover from the generator, connect F conclusion (it is specified by an arrow) to weight, start the engine, consider tension on the battery and compare to the standard. If tension is higher standard, replace tension regulator. If tension is lower standard, check the generator (or in the absence of the ampermeter hand over in a workshop of car service). |
| 16. If there is an ampermeter, turn on it in the scheme of charging (see rice. The scheme for check of current of the category of the battery). In the absence of the ampermeter it is possible to use the current transformer. This device inexpensive, is always available on sale and gives quite exact evidences. |
| 17. Bring engine turns to 2000 rpm, measure current at the switched-off consumers. Then turn on a driving beam of headlights and the fan of a heater (the switch establish in the situation HI). Measure current and compare to the values given in subsection 3.3.1. |
| 18. If the measured current is less standard, repair or replace the generator. |
