(2)The voltmeter reading must be zero(0)
when the starter switch is in OFF position.
It must be lower than the battery voltage
when the switch is in ON position(the
engine will not start).
(3)With one ammeter lead short-circuited,
start the engine.
(4)Read the voltmeter when the ammeter
reading is below five amperes and the
engine is running at 1800 rpm and also at
2500 rpm with all electrical loads turned
off. The voltage setting varies with
alternator temperature. Generally, the
higher the alternator temperature, the
lower the voltage setting.
Connections for testing voltage setting

Voltage setting
[at 20 C (68 F)] 14.7 0.3V
2.4.Testing output characteristics
(1)Disconnect the battery ground(negative)
cable
(2)Connect one ammeter lead to the B
terminal of the alternator and the other
lead to the positive terminal of the battery.
Connect one voltmeter lead to the B
terminal and the other lead to the ground.
(3)Connect the battery ground cable.
(4)Start the engine.
(5)Turn on all electrical loads.
(6)Increase the engine speed. Measure the
maximum output current at the specified
alternator speed when the voltmeter
reading is 13.5 volts.
-
2.5.Removal
(1)Disconnect the battery cables.
(2)Disconnect the lead from the B terminal
of the alternator.
(3)Disconnect the connector from the
alternator.
(4)Loosen the brace and support bolts. Move
the alternator toward the engine and
remove the drive belt.
(5)Remove the alternator.
