1) General

These adjustments and test procedures are applicable to testing and adjusting the generator set after
major repair, major parts replacements, or overhaul.
IMPORTANT
In order to perform most of the following test, a load bank with an EF interlock circuit
is required. However, if no EF interlock is available on a load bank, see special
procedure in the EF Bypass section for testing the EF circuit.

2) Testing the 400 Hz. Generator Set

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 the high bar on the dipstick.
(3) Check radiator coolant level.
(4) Check tension of drive belt.
(5) Inspect for oil, fuel and coolant leaks.
(6) If the setting of the output voltage coarse adjustment potentiometer on the voltage regulator has
been disturbed, set it at center position (halfway between full clockwise position and full
counterclockwise position).
(7) Check control panel lights circuit breakers by pressing panel "LAMPS" push button switch. If
panel lights operate, the circuit breaker, switch, and lamps are good.
(8) Check fault indication lights by pressing "TEST/RESET" push button switch. If fault code display
lights up, the control circuit breaker is good.
(9) Make a general inspection of all wiring, and terminals. Inspect the equipment to be certain no
damage will result from starting the engine.
