1.
Position generator in holding fixture.
NOTE
Ground polarity of energizer or battery
and generator must be the same. Use a
fully charged battery and a 10-ohm
resistor rated at six watts or more
between generator no. 1 terminal and
battery.
2.
Make connections as illustrated, except leave carbon
pile disconnected.
3.
Slowly increase generator speed and observe
voltage.
(a) If voltage is uncontrolled with speed and
increases above 15.5 volts on a 12-volt system,
check for a grounded brush lead clip (see
subparagraph a). If not grounded, replace
regulator
and
check
field
winding
(see
subparagraph b).
(b) If voltage is below 15.5 volts on a 12-volt system,
connect carbon pile as shown.
