1.
Check drive belt adjustment 86.10.05.
2. . Disconnect the multi-socket connectors.
3.
Provide a test circuit as shown.
CAUTION: The alternator contains polarity sensitive
components that may be irreparably damaged if
subjected to incorrect polarity. Observe polarity of
alternator and battery terminals.
4.
Do not connect the variable resistor into the test
circuit until instructed and do not connect it as;ross
the battery for longer than is necessary to perform
the check.
5.
Run the engine.
6.
If the voltmeter reading fluctuates with speed and
exceeds 15.5 volt the indication is that the regulator
should be replaced.
7.
If the voltmeter reading is steady below 15.5 volt
connect the variable resistor into the test circuit as
shown.
8.
Hold the speed at approximately 5000 alternator
rev/min (1800 to 2400 engine rev/min). Adjust the
variable resistor to obtain the maximum ammeter
reading.
9.
The ammeter reading should now be within 10% of
the nominal output given in data.
10.
If the ammeter reading is not correct the indication is
that the alternator requires overhaul or replacement.
