6 V6-3.7L (2009)
Current
NOTE:
1
Since the charging current decreases rapidly after starting the engine, carry out the following procedure quickly, and read the maximum current
value.
1. Verify that the battery is fully charged.
2. Verify that the generator and A/C drive belt deflection/tension is correct. See: Engine, Cooling and Exhaust/Engine/Drive Belts, Mounts, Brackets
and Accessories/Drive Belt/Testing and Inspection
3. Disconnect the negative battery cable.
4. Connect a tester, which can read 120 A or more, between generator terminal B and the wiring harness.
5. Connect the negative battery cable.
6. Turn off all electrical loads.
7. Start the engine.
8. Increase engine speed to 2,500 rpm.
NOTE:
1
When the electrical load on the vehicle is low, the specified current cannot be verified although the generator is normal. In this case,
increase the electrical load (Leave the headlights turned on for a while, then discharge the battery, or use a similar method.) and recheck.
2
When the generator itself or the ambient temperature are too high, the specified current also cannot be verified. In this case, cool down the
generator and recheck.
9. Turn the following electrical loads on and verify that the current reading increases more than the minimum value indicated below.
1
Headlights (high-beam)
2
Blower motor (HI)
3
Rear window defroster
4
Brake lights
Generator generated current minimum value
-
70% of the nominal output current (nominal output current: 110 A)
-
[Ambient temp. 20 °C {68 °F}, voltage 13.0-15.0 V, both engine and generator are hot]
Generator Inner Parts
Rotor
1. Measure the resistance between the slip rings using a tester.
-
If not within the specification, replace the rotor.
Generator rotor resistance (between slip rings) [20 °C {68 °F}]
-
1.8-2.2 ohm
2. Verify that there is no continuity between the slip ring and core using a tester.
