Electrical Connectors
When you replace electrical components or perform diagnostic
tests, you must disconnect electrical connectors in many
instances.
The following discussion will help you recognize connectors in
electrical drawings and show you how to disconnect and connect
them.
Electrical Connector Drawings
In most of the electrical drawings in this section, the physical shape
of electrical connectors has been eliminated to clarify testing
procedures.
Atypical electrical drawing illustrates several connectors.
1
Items (1), (2), (3), (4), (7) and (8) are terminals that are
located inside of electrical connectors. The dashed line between
two terminals [e.g., between terminal (7) and (8)] means that they
are a part of the same connector but have been disconnected for
testing.
Note that Terminal (7) is directly connected to the CD Unit (9) (no
connectors between the terminal and CD Unit). When you
disconnect an electrical connector to test a component, it is very
important that you disconnect the FIRST CONNECTOR.
Terminals (1), (3) and (7) are examples of how the first connector is
illustrated.
