SERVICE ADJUSTMENT PROCEDURES

VOLTAGE DROP TEST OF ALTERNATOR OUTPUT LINE

This test determines whether the wiring from the a-
ternatorBterminal to the battery (+) terminal (in-
cluding the fusible link) is in a good condition or not
Always be sure to check the following before the
test_

Alternator installation

Alternator drive belt tension (Refer to GROUP
11Service Adjustment Procedures )
Fusible link

Abnormal noise from the alternator while the
engine is running

(21 Turn the ignition switch to the OFF position.

(31 Disconnect the negative battery cable

(4) Disconnect the alternator output wire from the al-
ternatorBterminal and connect a DC test am-
meter with a range of 0 - 100 A in series between
theBterminal and the disconnected output
wire (Connect the (+) lead of the ammeter to the
Bterminal, and then connect the (~) lead of the
ammeter to the disconnected output wire.

NOTE

A clamp-type ammeter which enables measure-
ments to be taken without disconnecting the a-
ternator output wire should be recommended:
Because, if a vehicle in which the voltage may
have dropped due to a imperfect connection at
the alternator "Bterminal is being inspected,
and so if the alternatorBterminal is loosened
and a test ammeter is connected, the connection
will be complete at the time of connection and
will bere-
the possibilityof finding problems
duced.

(5) Connect a digital-type voltmeter between the al-
ternatorterminal and the battery (+) termi-
nal, (Connect the (+) lead of the voltmeter to the
Bterminal, and then connect the (~) lead of the
voltmeter to the battery (+) cable )
