This test determines the condition of the wiring
from the generator
terminal to the battery
terminal (including the fusible link).
(1) Be sure to check the following before testing:
l
Generator installation and wiring connec-
tions
l
Generator drive belt tension (Refer to
GROUP 00 Maintenance Service.)
l
Fusible link
l
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
terminal. Connect a DC test am-
meter with a range of 0 100 A in series be-
tween the
terminal and the disconnected
output wire. (Connect the
lead
amme-
ter to the
terminal. Connect the
of the ammeter to the disconnected output
wire.)
NOTE
An inductive-type ammeter which enables mea-
surements to be taken without disconnecting
the generator output wire is recommended.
Using this equipment will lessen the possibility
of a voltage drop caused by a loose
terminal
connection.
(5) Connect a digital-type voltmeter between the
generator
terminal and the battery
termi-
nal. (Connect the
lead of the voltmeter
to the
terminal. Connect the
lead of
the voltmeter to the battery
cable.)
