The switch may be bent, broken, rusted or immovable. If this is the case, report to organizational maintenance for
GENERATOR VOLTAGE DROPS WHEN LOAD IS APPLIED OR INCREASEDl; VOLTAGE
Check to see if generator is overloaded. Position the ammeter phase selector switch (fig. 2-3) in each of the three posi-
tions in turn, and at the same time observe the current indicator meter (fig. 2-3). The meter should not give an indi-
cation greater than 100% in any phase with any type load. With a straight resistive load, such as incandescent light-
ing, it should not exceed 80% (100% at 1.0 power factor).
If the meter indicates a load greater than these values in any phase, reduce the load. Balance the
load on each of the three phases, if possible. Position the voltage selector switch (fig. 2-3) in each of
the six positions, in turn, and obtain a voltmeter reading in each of the six positions.
If the voltage drops under load, the voltag regulator is defective. Report the condition to organizational maintenance
NO POWER AVAILABLE AT OUTLET RECEPTACLE (MODEL MEP-017A)
Check to see if the fuse is burned, broken, or cracked. Open the front of the control box by unlocking the five fasteners located near
the top and at the sides of the control panel.
If the fuse has any evidence of the above, replace fuse. Refer to figure 3-2.
