Triumph Tiger Explorer XR 2017 Service Manual page 20

Tiger Explorer XR Series
At the back of the Service Manual a full colour layout circuit diagram is used to show the main electrical
components in a position similar to the actual position on the motorcycle.
Both of these circuit diagrams use similar symbols to illustrate the various system components and will be
accompanied by a key indicating circuit diagram components and wiring colour codes.
Circuit diagrams also depict the inner workings of a switch housing (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 description of the symbols found in the circuit diagrams used in all Triumph Service Manuals.
Connector
1
2
3
4
This illustration is used to show all multiplug 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
number 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 current 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
3
2
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 indicates the
position of the fuse in the fuse box.
