Systems Description
The alternator-field circuit breaker and alternator-output
circuit breaker are located on the right subpanel.
CAUTION
Do not pull alternator circuit breaker to turn off
electrical system except in an emergency .
The alternator output is controlled by a regulator to keep
the battery in a fully charged condition. Monitoring the am-
meter for proper operation of the alternator is the same as
for a generator installation . A zero reading, which is nor-
mai in cruising flight, indicates that the battery is fully
charged and that the alternator output has been adjusted
by the voltage regulator to balance the load of the electri-
cal equipment in use.
Should an alternator or regulator become inoperative, in-
dicated by a heavy discharging or widely fluctuating am-
meter indication. turn the ALT switch to OFF, and mini-
mize the electrical current consumption, s ince only battery
power is available . Have the difficulty corrected before the
next fi i g ht.
Refer to HANDLING, SERVICING AND MAINTENANCE
Section for minor maintenance of the alternator.
