(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
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.
