(6) Connect a tachometer. (For the procedure for
connecting the tachometer, refer to GROUP
- On-vehicle Service.)(7)
kkconnect the negative battery cable.
(8) Leave the hood open.
(9) Start the engine.
(lO)With the engine running at 2500 rpm, turn the
headlights and other lights on and off to adjust
the generator load so that the value displayed
on the ammeter is slightly above 30A.Limit value: Max. 0.3 V
NOTE
When the generator output is high and the value
displayed on the ammeter does not decreaseto
30A, set the value to 40A. Read the value
displayed on the voltmeter at this time.
In this case the limit value becomes max. 0.4V.
Adjust the engine speed by gradually decreas-
ing it until the value displayed on the ammeterOUTPUT CURRENT TEST
is 30A. Take a reading of the value displayed
on the voltmeter at this time.
(11) If the value displayed on the voltmeter is above
the limit value, there is probably a malfunction
in the generator output wire, so check the wiring
between the generator
“IS” terminal and the bat-tery
(+) terminal (including fusible link).
If a terminal is not sufficiently tight or if the har-
ness has become discolored due to overheating,
repair and then test again.(12)After the test, run the engine at idle.
(13)Turn off all lights and turn the ignition switch
to the OFF position.
(14)Disconnect the negative battery cable.
(15)Disconnect the ammeter, voltmeter and tachom-
eter.
(16)Connect the generator output wire to the genera-
tor “B” terminal.
(17)Connect the negative battery cable.

This test determines whether the generator outputs
normal current.(1) Before the test, always be sure to check the
following.l Generator installation
l
Battery (Refer to GROUP 54 - Battery.)
NOTE
The battery to be used should be slightly dis-charged. The load in a fully-charged battery
will be insufficient and the test may not be able
to be carried out correctly.l Generator drive belt tension (Refer to
GROUP 11- On-vehicle 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
“B” terminal and connect a DC testammeter with a range of O-100 A in series
between the “B” terminal and the disconnected
output wire. (Connect the
(+) lead of the amme-ter to the
“B” terminal, and then connect the(-) lead of the ammeter to the disconnected
output wire.)
Caution
Never use clips but tighten bolts and nutsto connect the line.
Otherwise loose
connections (e.g. using clips) will lead to
a serious accident because of high current.
NOTE
A clamp-type ammeter which enables measure-
ments 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 voltmeterto the “B” terminal, and then connect the (-)
lead of the voltmeter to the ground.)
(6) Connect a tachometer. (For the procedure forconnecting the tachometer, refer to GROUP
11 - On-vehicle Service.)
(7) Connect the negative battery cable.
(8) Leave the hood open.(9) Check to be sure that the reading on the
voltmeter is equal to the 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.
(1O)After turning the light switch on and turning on
the headlights, start the engine.
(1l)lmmediately after setting the headlights to high
beam and turning the heater blower switch to
the high revolution position, increase the enginespeed to 2,500
r/min and read the maximum
current output value displayed on the ammeter.
Limit value: 70% of nominal current output
NOTEl
For the nominal current output, refer to the
Generator Specifications.l
Because the current from the battery will
soon drop after the engine is started, the
above step should be carried out as quickly
as possible in order to obtain the maximum
current output value.l The current output value will depend on
the electrical load and the temperature of
the generator body.l
If the electrical load is small while testing,the specified level of current may not be
output even though the generator is normal.
In such cases, increase the electrical load
by leaving the headlights turned on for sometime to discharge the battery or by using
the lighting system in another vehicle, and
then test again.l
The specified level of current also may not
be output if the temperature of the generator
body or the ambient temperature is too high.
In such cases, cool the generator and then
test again.
(12)The reading on the ammeter should be above
the limit value. If the reading is below the limit
value and the generator output wire is normal,
remove the generator from the engine and check
the generator.(13)Run the engine at idle speed after the test.
(14)Turn the ignition switch to the OFF position.
(15)Disconnect the negative battery cable.
(16)Disconnect the ammeter, voltmeter and
tachometer.(17)Connect the generator output wire to the
generator “B” terminal.
(18)Connect the negative battery cable.

ABNORMAL WAVE-FORMS EXAMPLES
NOTE
1.The size of the wave-form patterns differs largely depending on the adjustment of the variable knob
on the analyzer.
2.Identification of abnormal wave-forms is easier when there is a large output current (regulator is not
operating). (Wave-forms can be observed when the headlights are illuminated.)
3.Check the conditions of the charge light (illuminated/not illuminated) also, and carry out a total check.
