OUTPUT CURRENT TEST
This test is to check that the alternator output current is identi-
fied with the rated current.
PREPARATION
1. Prior to test, inspect the following items and repair if
necessary.
1) Be sure that the battery installed in the vehicle is
normal.(See Battery )
NOTE
When measuring output current, necessarily use
a slightly discharged battery. Fully charged bat-
tery is not enough to use for correct test owing
to insufficient load.
2) Inspect the drive belt for tension. (See Engine body )
2. Turn the ignition switch OFF.
3. Disconnect the battery ground cable.
4. Disconnect the alternator output wire from the alternator
B terminal.
RESULT
1. If voltmeter reading is within the standard, it is normal.
Test voltage Maximum 0.2V
2. If voltmeter reading is more than the standard, mostly wir-
ing is faulty. In this case, inspect wirings between the alter-
nator and the battery (+) terminal as well as between the
alternator
B terminal and the fusible link.
3. Also prior to re-test, check and repair the connecting part
for looseness and the harness for discoloration by
overheating.
4. After test, adjust the engine speed at idle and turn the light
and ignition switch OFF.
5. Disconnect the battery ground cable.
6. Disconnect the ammeter and voltmeter.
7. Connect the alternator output lead wire to the alternator
B terminal.
8. Connect the battery ground cable.
