Testing the Generator Set
The following test procedures may be used for testing the unit after major repairs or
overhaul.
A. Preoperational Test-Procedures
Perform the following checks, tests,
and operations before starting the unit.
(1) When testing the unit, open all engine access doors and remove canopy access
panel on the left side of the vehicle. Remove control box left access panel.
Figure 1 illustrates interior with panel removed. Most of the terminal boards
which may be used for testing are located in this area (Ref. Fig. 3).
(2) 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 (see l-2,
Para. 4, A). Be certain that all connections are secure, and the generator
"N " cable is grounded.

u ricant level in transmission and rear axle.
(5) Check radiator coolant level (Ref. 2-2, Para. 5, I, (3), (b).
(6) Check brake fluid and check battery water.
(7) Check tension of fan and alternator V-belts. (See 2-2, Figure 18 and 19).

If governor throttle linkage was disturbed, check all linkage to make certain
engine speed may be controlled when the engine is started. See Figure 9.
(9) Inspect for oil, fuel, and coolant leaks.

If the setting of the voltage regulator rheostat (44, Fig. 2) has been disturbed,
set it at CENTER position (halfway between full clockwise position and full
counterclockwise position).
