ALTERNATOR FAILURE

Alternator output failure is indicated by the fact that the
battery discharge light will illuminate and the ammeter will
show a negative number.
To verify the alternator has failed:
 Electrical Load ................................................ Reduce
 Ammeter ........................................ Positive indication,
 Ammeter ...................................... Negative indication,
The alternator circuit breaker may also have tripped.
Output failure may be the result of a mechanical failure of
the alternator, failure of the alternator drive belt or a
momentary over-voltage condition.
To re-set the DC system:
 Battery Master Switch ............................................. Off
 Allow at least 10 seconds delay
 Circuit Breakers .............................. Check, Pushed In
 Battery Master Switch ............................................ On
If alternator power is NOT restored, determine what
electrical equipment is essential to continue the flight and
land as soon as practical. Battery power is the only
source of electrical power. Anticipate complete electrical
failure.
 Electrical Load ................................................ Reduce
