SECTION 3. ADJUSTMENT/TEST
1. General
djustment and test procedures are most applicable to testing and adjusting the generator set after a major
repair, replacement of parts, or overhaul.
2. Generator Set Test
A. Pre-operational Test Procedures
(1) Connect cables from the generator output terminals to a load bank. Use cables of the same size
and length as those to be used in service. Be sure the generator output “N” cable is grounded.
(2) Check engine oil level. Oil should be at FULL mark on gage rod.
(3) Check radiator coolant level
(Ref. Section 2-1, Para. 6, H).
(4) Check tension of fan and generator V-belts.
(5) If governor throttle linkage was disturbed, check all linkage to make certain engine speed may be
controlled when the engine is started.
(6) Inspect for oil, fuel, and coolant leaks.
(7) If the setting of the voltage regulator rheostat
(See TM-759 or OM-2020 for your particular regula-
tor)
has been disturbed, set it at CENTER position
(halfway between full clockwise position and full
counterclockwise position).
(8) Check engine circuit fuse
(26, Fig. 1)
by placing panel light switch
(16)
in ON position. If panel
lights
(13)
operate, the fuse
(26),
switch
(16),
and lamps are good.
(9) Check fault indicating lights
(9)
by pressing test switch
(8).
If lights glow, fuse
(11)
and indicating
lamps are good.
(10) Make a general inspection of all wiring and terminals. Inspect the equipment to be certain no
damage will result from starting the engine.
(11) At initial start-up after generator overhaul or repair, “flash” the exciter field by momentarily apply-
ing 12-V DC to the field windings as follows:
CAUTION: ENGINE MUST NOT BE RUNNING WHEN FLASHING FIELD IF VOLTAGE REGULATOR
DAMAGE IS TO BE PREVENTED.
(a) Flashing exciter field using test box.
If a test box
(see Sect. 1-3, Fig. 3)
is available, connect it to receptacle connector
(Sect. 1-3, Fig.
4).
(aa) Rotate the selector knob
(Sect. 1-3, Fig. 3, item 1)
to position 8.
(bb) Use two jumper leads, each equipped with an alligator clip and a test prod, to connect
12-V DC power to test jacks
(2 and 3)
on the test box. Connect positive jumper from input ter-
minal on starter solenoid to red test jack. Connect negative lead from starter ground terminal
to black test jack.
