TROUBLESHOOTING

Finding a problem in the electrical system is not difficult if you
know basic electricity and understand the arrangement of
the electrical system. Use the wiring diagrams at the end of
this manual as your guide. 

Ac curate testing equipment  is als o necess ary. The
instruments normally used are a voltmeter, ammeter,
ohmmeter and test light.

Many times the problem can be found by visual inspection of
the components in the circuit. Corrosion on terminals, loose
connections or bad wiring are the causes of many problems.

Each circuit in the system has a fuse for protection against
overloads. Remember that a burnt fuse is an indication of an
overload or 

SHORT

 circuit, not an 

OPEN 

circuit.

If you did not find the cause of the problem during the visual
inspection, use a voltmeter to check the voltage at several
points in the circuit, or measure voltage drop across the
component. Normally, the best method is to start at the
furthest component in the circuit and move backwards
toward the power supply. An ohmmeter can be used to
measure the resistance in any component. Remember to
disconnect the component from the power supply before you
connect the ohmmeter.
