General Information

Circuit Diagrams

Circuit diagrams are created to provide a 'picture' of the
electrical system and to identify the route taken by each
individual wire th rough the system, in order to identify
which components it feeds and which connectors the wire
runs through. Circu it diagrams are an essential tool for
fault finding, as it is possible to locate start and finish
points for a circuit without l')aving to manually trace the
wire through the motorcycle itself. Circuits diagrams may
look confusing at first but when they are studied closely
they soon become log ical.
Due to the complex circuits and the number of individual
wires, Triumph uses two types of circuit diagram in its
service manuals.
•
Within the manua
diagra ms are used to show the layout of the
main circu its of the motorcycle. These a re :
Engine managemenUig n ition,
Starting and Charging and Auxiliary and
Accessory. I n these diagrams no attempt is
made to show the components of the system
in any particular order or position in relation
to the motorcycle.
At the back of the se rvice manual a full
colour layout circuit d iagram is used to show
the main electrical com ponents in a position
similar to the
motorcycle.
Both of these circuit diagrams use similar symbols to
illustrate the various system components and will be
accompanied by a key to circuit diag ram components and
wiring colour codes.
Circuit diag rams also depict the inner workings of a switch
cube (I.E. which wire connects to which when a switch is
turned from one position to another) so that a test of that
switch can be made using the wire terminals in the
connector instead of disassembling the switch itself.

Glossary of Circuit Diagram Symbols

The following is a descri ption of the symbols found in the
circuit diagrams used in all Triumph service manuals.
Connector
This illustration is used to show all m ulti-plug type
electrical connectors on Triumph circuit diagrams. The
numbers in the box relate to the terminal numbers of the
connector pins. On ECMs with two connectors, the
num b er would be prefixed with the letters 'A' or 'B' to
identify each connector. An additional number outside the
box will identify the component.
Diode
An electrical one-way valve. Diodes allow current to flow
in one direction but will not allow it to return. The arrow,
which forms part of the diode symbol, indicates the
direction of cu rrent flow.
Electromagnetic Winding <solenoid)
An electromagnetic winding (or solenoid) is used to
convert an electrical current into a lateral movement. This
can then be used to operate switches (as used in relays> or
other components such as fuel injectors or secondary air
injection solenoids.
Fuse
�2 �3
or
A fuse is a device which protects a circuit in the event of a
fault. The fuse will 'blow' should a short circuit occur,
protecting that circuit from further damage. The number
next to the fuse on the circuit diagram ind icates the
position of the fuse in the fusebox.
