REGULATED VOLTAGE TEST
Voltmeter
Load
This test determines if the
control module
is correctly controlling the generator output voltage.
(1) Before tesing, be sure to check the following:
l
Generator installation and wiring connections
l
Battery fully charged. (Refer to GROUP 54
Battery.)
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) Connect a digital-type voltmeter between the battery
terminal and the ground. (Connect the lead
of the voltmeter to the battery terminal. Connect
the
lead of the voltmeter to a secure ground
or to the battery
terminal.)
(5) Disconnect the generator output wire from the gener-
ator
terminal.
(6) Connect a DC test ammeter with a range of O-l OOA
in series between the
terminal and the
Field
terminal
Field
terminal
output wire. (Connect the
lead of the
ammeter to the
terminal. Connect the lead
of the ammeter to the disconnected output wire.)
(7) Reconnect the negative battery
(8) Make sure all lights and accessories are off.
(9) Connect a tachometer and start the engine.
(10) Increase the engine speed to approx.
(11) Read the voltmeter when the current output by the
generator becomes 10 A or less.
(12) If the voltage reading conforms to the value in the
voltage regulation table, the voltage regulator is oper-
ating normally.
If the voltage is not within the standard value, a
malfunction of the voltage regulator or generator
exists.
(13) After the test, lower the engine speed to idle speed.
the ignition switch to the “OFF” position.
Disconnect the negative battery cable.
(16) Disconnect the ammeter, voltmeter, and tachometer.
(17) Connect the generator output wire to the generator
terminal.
(18) Connect the negative battery cable.
