GENERATOR FAILS TO BUILD UP RATED VOLTAGE
Step 1.
Perform all steps under table 4-3, Malfunctions No. 1. If this does not reveal defective part, go on to
step 2.
Step 2.
Inspect for a defective rotating rectifier diode as follows:
a.
Model MEP018A.
(1)
Refer to paragraph 81f (1). Replace defective diodes. If diodes are not defective,
go on to step 3.
b.
Model MEP-023A.
(1)
Refer to paragraph 8-2f(1). Replace defective diodes. If diodes are not
defective, go on to step 3.
Step 3.
Inspect generator rotor and stator components as follows:
a.
Inspect the rotor shaft at each end for evidence of nicks, rust or wear. Inspect the
rotor assembly to be sure all windings are properly pressed into the core slots.
Inspect the core for wear and replace a badly scored or defective rotor assembly.
b.
Inspect the field windings and leads for damaged or broken wires. Inspect the main
frame for damage and broken welds and for nicks and burrs around the mounting
flanges.
c.
Test generator rotor and stator components for model MEP-023A as follows:
(1)
Stator, refer to paragraph 8-2b. (1).
(2)
Rotor, refer to paragraph 8-2b. (2).
(3)
Exciter field windings, refer to paragraph 8-2b. (3).
d.
Test generator rotor and stator components for model MEP-018A as follows:
(1)
Rotor, refer to paragraph 8-1f. (2).
(2)
Stators, refer to paragraph 8-1f. (3).
