TROUBLESHOOTING
Troubleshooting can be difficult. On the following pages there is a list of possible
problems. To make a repair to a problem, make reference to the cause and correction.
The list of problems, causes and corrections will only give an indication of where a
possible problem can be, and what repairs are needed. Normally, more or other repair work is
needed beyond the recommendations in the list. Remember that a problem is not normally
caused only by one part, but by the relation of one part with other parts. This list can not give all
possible problems and corrections. The serviceman must find the problem and its source, then
make the necessary repairs.
