Loss Of Fuel Pressure; High Oil Temperature; Electrical Failures; Electrical Overload - Piper CHEROKEE WARRIOR II Pilot Operating Handbook

SECTION 3
EMERGENCY PROCEDURES

LOSS OF FUEL PRESSURE

Electric fuel pump ..................................................ON
Fuel selector ....................................check on full tank

HIGH OIL TEMPERATURE

Land at nearest airport and investigate the problem.
Prepare for power off landing.

ELECTRICAL FAILURES

ALT annunciator light illuminated:
Ammeter...............................Check to verify inop. alt.
If ammeter shows zero:
ALT switch ...........................................................OFF
Reduce electrical loads to minimum:
ALT circuit breaker.............................Check and reset
ALT switch .............................................................ON
If power not restored:
ALT switch ...........................................................OFF
If alternator output cannot be restored, reduce
electrical loads and land as soon as practical. The
battery is the only remaining source of electrical
power.
ELECTRICAL OVERLOAD (Alternator over 20
amps above known electrical load)
FOR AIRPLANES WITH INTERLOCKED BAT
AND ALT SWITCH OPERATION.
Electrical load ..................................................Reduce
If alternator loads are reduced:
ALT switch ...........................................................OFF
Land as soon as practical. Battery is the only re-
maining source of power. Anticipate complete
electrical failure.

ELECTRICAL OVERLOAD (Alternator over 20
amps above known electrical load)
FOR AIRPLANES WITH SEPARATE BAT
AND ALT SWITCH OPERATION
ALT switch .............................................................ON
BATT switch .........................................................OFF
If alternator loads are reduced:
Electrical load .............................Reduce to Minimum
Land as soon as practical.

NOTE
Due to increased system vol-
tage and radio frequency noise,
operation with ALT switch ON
and BATT switch OFF should
be made only when required by
an electrical system failure.
