(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.

BATTERY INSPECTION
BAlTERY VISUAL CHECK (1)
The battery contains a visual test indicator which gives blue
signal when an adequate charge level exists, and white signal
when charging is required.
BAlTERY VISUAL CHECK (2)
Make sure ignition switch is in Off position and all battery
feed accessories are Off.
1.Disconnect ground cable from battery before disconnecting
(+) cable.
2. Remove battery from vehicle.
CautionCare should be taken in the event battery case is
cracked or leaking to protect hands from the electro-
lyte. A suitable pair of rubber gloves (not the house-hold type) should be worn when removing battery
by hand.
3.Inspect battery carrier for damage caused by loss of acid
from battery. If acid damage is present, it will be necessaryto clean area with a solution of clean warm water and
baking soda. Scrub area with a stiff bristle brush and wipe
off with a cloth moistened with ammonia or baking soda
in water.
