Check current output of the generator (2.4 L)



This test determines whether the current impact of the generator nominal value.

Preparing for inspection
Before starting the test, check the following and, if necessary, repair:
Check that the battery installed in the vehicle is correct. The procedure for checking the battery, see "Battery."

NOTE
The battery used in conducting this test, should be slightly discharged. The load created by a fully charged battery, not suitable for the correct performance of this test.

Check the tension of the alternator drive belt.
Turn the ignition switch to ?�OFF?�.
Disconnect the (-) battery terminals.
Disconnect the output wire from the terminal "B" of the generator.
Connect an ammeter (DC, with a range of 0-100 A) in series between the output of the "B" and the generator output wire. Make sure that the (-) lead of the ammeter connected to the output wire, disconnected from the generator.

NOTE
Securely and tightly fasten each connection, since the conclusions will be fed large current. When connected to an electrical circuit using clamps (type "crocodile").

Connect a voltmeter (with a scale of 0-20) between terminal "B" of the generator and "weight". Connect (+) wire of the voltmeter to the "B" of the generator, and then the (-) lead of the voltmeter to a suitable "weight" (to the body).

Driving test current output of the generator
Fig. 7.20. Driving test current output of the generator


Connect the tachometer control in accordance with the instructions of the manufacturer of the device. Attach the wire to the (-) terminal of the battery (Fig. 7.20).
Leave the engine cover open.

The verification procedure
Make sure that the voltmeter shows battery voltage. If the meter reads 0, then there is a break between terminal "B" of the generator and the (-) terminal of the battery. Check a burnt fuse or bad connection with "weight".
Start the engine and turn on the headlights.
Turn on the main beam headlights and the heater fan switch is set to position ?�HIGH?�, then sharply increase the frequency of engine speed to 2500 min -1 and read the maximum value of the current impact of the generator (featuring an ammeter).

NOTE
After starting the engine the current impact of the generator decreases rapidly. Carry out the checks as soon as possible to have time to measure the maximum current output.

Analysis of the results
The ammeter reading should be higher than the maximum permissible value. If the ammeter below the limit value, and thus the circuit output ?�B?� generator is OK, then remove the generator from the car, and make an inspection on the stand.
Limit: 95 A generator, a minimum of 63.0 A.

NOTE
Rated recoil generator stamped on the nameplate attached to the body of the generator.
The magnitude of return current varies depending on the load on the generator and the temperature of the generator housing. Therefore, the nominal value of the recoil force can not be achieved. In such cases, increase the electrical load (in order to discharge the battery), turn on while the main beam headlights or connect the outdoor lighting system in another car. The nominal value of the current impact of the generator may not be obtained due to overheating of the generator frame or at too high ambient temperature. In such cases, allow the generator to cool down, and then re-run the test.

Once validated, the current impact of the generator gradually lower the revolution of the crankshaft of the engine to idle speed, then turn the ignition switch to ?�OFF?�.
Disconnect the (-) battery terminals.
Remove the ammeter, voltmeter and check the tachometer.
Connect the output wire to the conclusion "B" of the generator.
Attach the wire to the (-) terminal of the battery.
