PROBLEM CHECK SOLUTION
Generator produces fluctuating
voltage.
Fluctuating engine speed. Check engine governor systems
for malfunction. Check load for
fluctuation.
Regulator stability. Adjust regulator stability.
Defective rectifier assembly. Check assembly for loose
connections. Test the diodes.
Loose terminal or load
connections.
Improve connections both
mechanically and electrically.
Defective regulator. Replace regulator.
Generator produces low voltage
when load applied.
Excessive load. Reduce load. The load on each leg
should be evenly balanced, and
rated current should not be exceeded
on any leg.
Large motor starting. Motor starting currents are too large
for the generator when starting.
Load power factor. Multiple motors sequence the motors
and start the largest motor first.
Reduce lagging power factor load.
Driver speed drop. Check driver. Check under frequency
setting on regulator Under frequency
voltage roll-off may be activated.
Line drop. If voltage is proper at generator
terminals but low at the terminals,
Increase external wire size.
Defective diodes, suppressor or
windings.
Test the generator using the 12
volt battery test as specified in the
test section. If the results indicate
generator problems. See continuity,
and diode tests.
Generator builds voltage from
start-up then goes to low (residual)
voltage.
Regulator protective circuit
operating.
Check indicators on regulator.
Correct problems and adjust
regulator as is required. Refer to
regulator manual.
Generator produces mechanical
noise.
Defective bearing. Replace bearing.
Loose or misaligned coupling. Tighten, realign, or replace coupling.
