GENERATOR PRODUCES LOW VOLTAGE, NO LOAD
CAUSE
Defective diodes, suppressor, or windings
Regulator inoperative
GENERATOR PRODUCES LOW VOLTAGE WHEN LOAD APPLIED
CAUSE
Excessive load
Large motor starting or low
Driver speed droop
Line drop
Defective diodes, suppressor, or windings
GENERATOR PRODUCES FLUCTUATING VOLTAGE
CAUSE
Fluctuating engine speed
Regulator stability
Regulator external rheostat
Defective rectifier assembly
Loose terminal or load connections
Defective regulator
CHECK AND REMEDY
Test the generator using the 12 volt battery test as specified in the testing section. If the results indicate generator problems, perform insulation, con-
tinuity, and diode tests as specified in the testing section.
Adjust or replace regulator. Consult regulator manual.
CHECK AND REMEDY
Reduce load. The load on each leg should be evenly balanced, and rated current should not be exceeded on any leg.
Motor starting currents are too large for the generator. When starting multiple motors, load powerfactor sequence the motors and start the largest
motors first. Reduce lagging power factor load.
Check driver. Check under frequency setting on regulator. Under frequency voltage roll-off may be activated.
If voltage is proper at generator terminals but low at load terminals, increase external wire size.
Test the generator using the 12 volt battery test as specified in the testing section. If the results indicate generator problems, perform insulation, con-
tinuity, and diode testsas specified in the testing section.
CHECK AND REMEDY
Check engine and governor systems for malfunctions. Check load for fluctuation.
Adjust Regulator stability. Refer to Regulator manual.
Replace defective or worn rheostat. Use shielded cable to minimize electrical noise.
Check assembly for loose connections. Test the diodes as specified in the test section.
Improve connections both mechanically and electrically.
Replace regulator.
