Generator and Excitation Circuit (cont.)

Trouble, Symptom & Condition

Test or Inspection

Corrective Action

No (or low) generator output
voltage in all phases.
Generator operating at 400 Hz
in AUTOMATIC mode.
(Continued)

f. Defective ballast

resistor(s), (See Fig. 5).

If output voltage was produced
when the generator set was
operated in MANUAL mode, the
resistors are good. If no voltage
was produced in MANUAL
mode, resistors could be
defective. Refer to Fig. 5 and
connect a jumper lead across
the ballast resistors. If an output
voltage is now produced,
replace resistor(s) as required.

g. Defective Amphenol

connector at voltage
regulator, or defective
wiring from regulator to
exciter field.

Disconnect voltage regulator
Amphenol connector (see
1-1;14,  Fig. 10). Using jumper
leads with clip and prod
terminals, connect ungrounded
12-V DC to terminals “E” and
“C” in loose plug. Connect
NEGATIVE to terminal “E”.
Connect POSITIVE lead to “C”
terminal (See Fig. 6).

If the generator will NOT
produce a normal voltage,
replace or repair Amphenol
connector and wiring between
voltage regulator and exciter
field as required.

h. Defective voltage

regulator.

All components in the excitation
circuit except the voltage
regulator have been tested in
steps (1) through (4) above.
This leaves only the regulator
as a cause of trouble. Replace
complete voltage regulator if the
magnetic amplifier regulator
430391C is used.  If solid state
amplifier 489812A is used,
replace PC board.
