workshop manual. Study the diagram to get a complete picture of what
makes up the circuit you are investigating. Tracing the circuit through
will identify switches, connectors, wire colours, fuses, power source, and
finally how the circuit is earthed.
Often trouble spots can be identified when other components related to
the circuit are also not working. If so, the chances are the fault lies either
in their shared fuse, a multi-pin connector, or the earth connection that
is common to those components.
Electrical problems often stem from simple causes, such as a loose
or corroded connection or a blown fuse. Never assume that it is the
component itself that is faulty without first investigating the circuit. If no
obvious fault can be found, then refer to your manual for specific tests
that can be done on the component itself.
