TROUBLE SHOOTING
SECTION 3
LOCATION AND CORRECTION OF
DIFFICULTIES ON-THE-ROAD
This section provides a check list calling the
operator's attention to the troubles which are most fre-
quently encountered on the road, and which can be
quickly remedied thereby eliminating many delays.
No attempt is made to explain general operation
and functions of equipment on the locomotive. For such
information refer to the other sections of this manual.

TROUBLE SHOOTING
F9-3-657
300 General
Safety devices automatically protect the equipment in
case of the faulty operation of most any component. In general, this
protection is obtained by unloading or preventing the loading of the
Diesel engine so that the locomotive loses its pulling power. The
locomotive can lose its power with the Diesel engine still running. An
exception is a hot engine alarm, which does not reduce the engine load
or speed.
When trouble is experienced, the general location and type of
difficulty is often indicated by the ringing of an alarm bell and the
lighting of one or more signal lights in the troubled units. The signal
lights are as follows: RED - Hot Engine; GREEN - Boiler Stopped;
BLUE - Alternator Failure; YELLOW - Low Oil; and WHITE - PC
Switch.

If Alarm Bells Ring
One or more of the signal lights will be
illuminated in the unit affected, Fig. 3-1.

TROUBLE SHOOTING
RED - Hot Engine
This alarm light indicates that the outlet engine
water temperature is about 208° F.
A hot engine alarm does not
reduce the engine load or speed. The alarm signal will not stop until
temperature returns to normal. In case of hot engine alarm, proceed as
follows:
1. Isolate engine. Isolating the engine will not stop alarm bell;
temperature must return to normal.
2. Check engine cooling water tank for correct level, Fig. 3-2. If there is
sufficient water in the system, allow engine to run at IDLE speed.

3.
See that all AC cooling fan contactors are closed, Fig. 3-3.
4. See that the shutters are open. If closed, check position of
"shutoff" valve in the air supply pipe to the shutter magnet valve.
5.
See that the "Control" switch is ON.

TROUBLE SHOOTING
GREEN -
Boiler Stopped
Indicates
steam
generator
has
stopped. To stop alarm signal, turn boiler switch OFF,
Fig. 3-4.
BLUE -
Alternator Failure
This alarm signal indicates that the
alternating current system has failed; traction motor blowers and
radiator cooling fans have stopped; No Voltage Relay (NVR) is opened
(de-energized), Fig. 3-5. The engine speed and load is automatically
reduced equivalent to No. 1 throttle position. The engine will STOP if
the "AC" system fails with the throttle in Run 5 or 6. Placing the
isolation switch in START stops the alarm signals.
Most "Alternator Failure" alarms
are "false" since this alarm occurs if the
engine is stopped for any reason while
"on the line." With an "Alternator
Failure" alarm and the engine stopped,
ALWAYS isolate and check cause of
engine stopping. Check:

overspeed trip, throttle must not be in STOP position, and fuel flow
through fuel return sight glass, Fig. 3-6, before trying to start an engine
that has shut down with no indication other than an "Alternator Failure"
alarm. If other alarm indications are present with the "Alternator
Failure" alarm, they must also be checked before starting the engine.
Overspeed Trip And Fuel Flow Check
Fig. 3-6
A "TRUE" AC failure is evident when the Blue light and bell are
ON with the engine running and the isolation switch in RUN. To correct
a "TRUE" AC failure, shut engine down and check auxiliary generator
field, alternator field and auxiliary generator (battery charging) fuses; all
MUST be good. See Fig. 3-7.
NOTE: If "Engine Run" switch is OFF, or PC light is ON (PC switch
open) the "Alternator Failure" alarm signals are inoperative.
YELLOW -
Low Oil
The tripping of the governor low oil alarm
button, Fig. 3-8, due to engine low oil pressure or high oil suction, will
