TROUBLESHOOTING
INTRODUCTION
This section is intended to suggest a
systematic approach to locating and
correcting generator or regulator
malfunctions. The sections are arranged
according to the symptoms of the problem.
The steps in each section have been
arranged in an attempt to do the easy checks
first then to prevent further damage when
troubleshooting a disabled machine.
The first and perhaps most important step of
troubleshooting should be to gather as much
information as possible from personnel who
may have been present during the failure.
Information on how long the generator had
been running, what loads were on the line,
weather conditions, what protective equip-
ment operated, etc., can help isolate the
problem.
Always make a thorough visual inspection
to check for any obvious problems before
attempting to run the generator.
WARNING
HIGH VOLTAGES CAN BE PRESENT
AT THE GENERATOR AND
REGULATOR TERMINALS. HIGH
RESIDUAL VOLTAGES CAN BE
PRESENT EVEN WITH THE
REGULATORDISCONNECTED OR
ITS FUSES REMOVED. SOME
EQUIPMENT (SUCH AS
SPACEHEATERS) MAY BE
ENERGIZED WHEN THE
GENERATOR IS OFF. TOOLS,
EQUIPMENT, CLOTHING, AND
YOUR BODY MUST BE KEPT CLEAR
OF ROTATING PARTS AND
ELECTRICAL CONNECTIONS.
SPECIAL CAUTION MUST BE TAKEN
DURING TROUBLESHOOTING SINCE
PROTECTIVE COVERS AND SAFETY
DEVICES MAY BE DISABLED TO
GAIN ACCESS AND MAKE TESTS.
BE CAREFUL. SERIOUS PERSONAL
INJURY OR DEATH CAN RESULT
FROM THESE HAZARDS. CONSULT
QUALIFIED PERSONNEL WITH ANY
QUESTIONS.
