TESTING
1.
Install alternator in test set-up as shown in figure.
Set regulated voltage on test set-up to 26 volts.
CAUTION
Connection
between
alternator
and
battery must not be disconnected when
alternator is running. Semiconductors
and regulator may be destroyed.
2.
Operate alternator at 2000 rpm for 2 minutes to
bring alternator to normal operating temperature.
3.
Reduce alternator speed to 1750 rpm.
4.
Adjust loading resistor until a reading of 10 amps is
achieved. Indicated voltage shall be 26 volts.
5.
