Alternator: Testing and Inspection
Output Current Test
Output Current Test
This test determines if the generator output current is normal.
1. Before testing, be sure to check the following:
-
Generator installation and wiring connections
-
Battery See: Battery
NOTE: The battery used should be slightly discharged. The load needed by a fully-charged battery is insufficient for an accurate test.
-
Generator drive belt tension
-
Fusible link
-
Abnormal noise from the generator while the engine is running
2. Turn the ignition switch to the OFF position.
3. Disconnect the negative battery cable.
4. Disconnect the generator output wire from the generator "B" terminal. Connect a DC test ammeter with a range of 0 - 100 A in series between the
"B" terminal and the disconnected output wire. (Connect the (+) lead of the ammeter to the "B" terminal. Connect the (-) lead of the ammeter to
the disconnected output wire.)
CAUTION: Never use clips but tighten bolts and nuts to connect the line. Otherwise loose connections (eg: using clips) will lead to a serious
accident because of high current.
NOTE: An inductive-type ammeter which enables measurements to be taken without disconnecting the generator output wire is recommended.
5. Connect a voltmeter with a range of 0 - 20 V between the generator "B" terminal and the ground. (Connect the (+) lead of the voltmeter to the "B"
terminal, and then connect the (-) lead of the voltmeter to the ground.)
6. Connect the negative battery cable.
7. Leave the hood open.
8. Check that the reading on the voltmeter is equal to battery voltage.
NOTE: If the voltage is 0 V, the cause is probably an open circuit in the wire or fusible link between the generator "B" terminal and the battery
(+) terminal.
9. Start the engine, and turn the headlights on.
10. Switch the headlights to high beam, turn the heater blower switch to High, increase the engine speed to Approx. 2,500 r/min, and read the
maximum current output displayed on the ammeter.
Limit value: 70 % of nominal current output
NOTE:
