Introduction
Trouble shooting for a portable light tower is an
organized study of a particular problem or series of
problems and a planned method of procedure for
investigation and correction. The trouble shooting chart
that follows includes some of the problems that an
operator may encounter during the operation of a
portable generator.
The chart does not attempt to list all of the problems
that may occur, nor does it attempt to give all of the
answers to solve the problems. The chart does give
those problems that are most apt to occur. To use the
trouble shooting chart:
1. Find the “complaint” depicted as a bold heading.
2. Follow down that column to find the potential cause
or causes.
Action plan
Think before acting
Study the problem thoroughly and ask yourself these
questions:
1. What were the warning signals that preceded the
problem?
2. Has a similar trouble occurred before?
3. What previous maintenance work has been done?
4. If the generator will still operate, is it safe to
continue operating it to make further checks?
Do the simplest things first
Most problems are simple and easily corrected.
Always check the easiest and most obvious things first.
Following this simple rule will save time and trouble.
Note: For trouble shooting electrical problems,
refer to the Wiring Diagram Schematic.
Double check before disassembly
The source of most problems can be traced not to one
component alone, but to the relationship of one
component with another. Too often, a machine can be
partially disassembled in search of the cause of a
certain trouble and all evidence is destroyed during
disassembly. Check again to be sure an easy solution
to the problem has notbeen overlooked.
Find and correct basic cause
After a mechanical failure has been corrected, be sure
to locate and correct the cause of the problem so the
same failure will not be repeated. A complaint of
“premature breakdown” may be corrected by repairing
any improper wiring connections, but something
caused the defective wiring. The cause may be
excessive vibration.
