3.19 LOSS OF FUEL PRESSURE
If loss of fuel pressure occurs, turn ON the electric fuel pump and check
that the fuel selector is on a full tank.
If the problem is not an empty tank, land as soon as practical and have
the engine driven fuel pump and fuel system checked.
3.21 HIGH OIL TEMPERATURE
An abnormally high oil temperature indication may be caused by a low
oil level, an obstruction in the oil cooler, damaged or improper baffle seals, a
defective gauge, or other causes. Land as soonas practical at an appropriate
airport and have the cause investigated.
A steady, rapid rise in oil temperature is a sign of trouble. Land at the
nearest airport and let a mechanic investigate the problem. Watch the oil
pressure gauge for an accompanying loss of pressure.
3.23 ELECTRICAL FAILURES
Loss of alternator output is detected through zero reading on the
ammeter. Before executing the following procedure, insure that the reading
is zero and not merely low by actuating an electrically powered device, such
as the landing light. If no increase in the ammeter reading is noted,
alternator failure can be assumed.
The electrical load should be reduced as much as possible. Check the
alternator circuit breakers for a popped circuit.
The next step is to attempt to reset the overvoltage relay. This is
accomplished by moving the ALT switch to OFF for one second and then to
ON. If the trouble was caused by a momentary overvoltage condition (16.5
volts and up) this procedure should return the ammeter to a normal reading.
If the ammeter continues to indicate "0" output, or if the alternator will
not remain reset, turn off the ALT switch, maintain minimum electrical load
and land as soon as practical. All electrical load is being supplied by the
battery.
