A. C. MODULAR GENERATOR SYSTEM
Page 50 of 56
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 against its printed rating using a capacitance
meter. Note that the capacitors must be disconnected from the generator and
each other (if there is more than one) before measuring.
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 Systems

Output voltage exceeds 260 volts or falls below 220 volts AC on a 240 volt line,
or below 210 on a 230 volt line:
a. Verify that the hydraulic system is not overheating by viewing the temperature as
displayed by the Command & Control Center. The temperature should not exceed
185° F. If the temperature is greater than 185° F, follow instructions for system
overheating (see hydraulic problems).
The hydraulic pump speed may be too low. Verify that the hydraulic pump speed
is in the required range (see
