B. Checking output
If the previous section "A" check is
satisfactory, check the output as follows:
a. After opening the battery switch,
disconnect the terminal B of the
alternator and connect an ammeter (50A
capacity) at the position shown in
Fig.598Y.
b. Connect the voltmeter between the
terminal B of the alternator and the
ground. Confirm that the voltmeter
indicates the battery voltage.
c. Close the key switch.
d. Start the engine and turn on all the
lamps. Immediately accelerate the
engine to 2000 rpm. Or more and
measure the maximum value indicated
on the ammeter.
e. If this value is more than 70％ of the
nominal output (refer to Section on
"Service Specifications”), the alternator
can be considered as working almost at
is factory.
NOTE:
To make the above judgment more accurate,
remove the alternator from the engine and
check it on a test bench.
5. Disassembly
a. Mark both brackets and the stator with a
scribe mark for assembly.
b. Remove the four through bolts. Pry
between the stator and front bracket④
with blade of a screwdriver.
Carefully separate the front bracket④ ,
pulley② and rotor assembly⑨ away
from the stator and rear bracket
assembly.
c. Place the rotor⑨ in a vice with soft
jaws and remove the pulley nut ① ,
washer, pulley spacer ⑧ and front
bracket④ from the rotor⑨ .
