A. C. MODULAR GENERATOR SYSTEM
Page 45 of 53
WARNING:
Do not attempt to measure the exciter field resistance while the system is operating.
Electrical shock may occur.
f. Exciter field capacitor may be faulty. Disconnect the exciter field from the field
capacitor. Using a screwdriver, short leads of capacitor together to discharge
capacitor. Measure capacitance using a capacitance meter. Capacitor should
have capacitance between 47 and 53 microfarads.
WARNING:
Do not attempt to test the field capacitor with the system running. Electrical shock
may occur.
g. The generator drive motor or coupling is faulty. Observe the generator while the
system is engaged. If the coupling is not turning, or if it is turning but the
generator is not, one or more of the coupling components may be damaged and
must be replaced. Also, verify that the coupling halves are mating. If the
coupling halves are not mating, remove the hydraulic motor from the generator
to inspect coupling and the rubber insert between the coupling halves. Replace
components as necessary, reposition and tighten coupling setscrew so both
halves of the coupling are mating correctly.
h. The pump is faulty. If no faults are found in steps a. through g., the problem is
likely to be a non-functional pump. Contact Smart Power
