Using the Wiring Diagram
The wiring diagram contains detailed information about the physical wiring within the machine. Every wire
segment is listed. Every connector is listed. Even the hidden splice points between wires are listed. This
information is useful for tracing a specic circuit as it passes through the machine.
Wire Numbers
Every wire is labeled with 3 items: Wire color, Wire Gauge, and Wire Number. The wire
number in the diagram is also printed on the actual wire used in the machine itself. The
wire number can be used to locate both ends of any wire segment in the machine.
Even though an individual electrical circuit may pass from one electrical connector to
another connector, that circuit may be made up from multiple wire segments. Each of
those segments is identied in this diagram. The circuit may pass through a splice point
or an intermediate connector (such as shown to the right), but each wire has only 2
connection points.
To trace a complete circuit, you would need to search for both ends of any wire number,
and see where they connect to the next wire segment. And then repeat this for each wire
segment in the circuit.
Service Tip: We use the Ladder Diagram to trace a circuit, but use
the harness diagram to trace the wires that make up that
circuit.
Splice Points
Another valuable piece of information in the harness
diagram is whether splice points exist in a circuit. Splice
points are used when a circuit needs to divide and travel
on to multiple destinations. Each splice point also has its
own unique identier (SPL) number. Power distribution
leaving the K1 (KSI) contactor is prime example of using
multiple splice points to distribute this common circuit
to multiple locations.
This knowledge can be helpful in troubleshooting. If
multiple components fail, and it is discovered that they
all share a common splice point, it can be concluded that
a wire failure occurred at or upstream from that splice
point.
Conversely, if only one component has failed, then it can
be concluded that a wire failure has not occurred in an
upstream wire segment.
Connector Numbers
Every harness connector throughout the system is given a unique connector ID number.
The ID numbers can be used to locate the connector in the machine and to look up pin
assignments in the “Electrical Connector Pin-Out Assignments” on page 153. This
information is used for tracing circuits and electrical signals throughout the machine. When
there are mating connectors to a device, the harness-side connector is shown for pin-out
assignment.
