Tiger Explorer XR Series
A device placed in a cable to reduce a voltage or restrict the maximum current a device can draw.
Splice
A hard cable joint where two or more cables are joined in the wiring harness. A potential source of both open
and short circuits.
Switches
A mechanical device for completing or breaking a circuit. There are three common types of switch: normally
open, normally closed and changeover.
Tracing Circuits
The following is a description of two types of common electrical failures, and some of the methods which may be
used to find them.
Open Circuit
A break in an electrical circuit - current cannot flow. Usually caused by a break in a wire or cable or by a loose
connection. Open circuits can often be intermittent, making diagnosis difficult.
Short Circuit
A 'short cut' in an electrical circuit - current bypasses the intended circuit, either to ground or to another, different
circuit. Often caused by failure of the cable insulation due to chafing or trapping of the wire. There are two
different types of short circuit - short to ground and short to battery Voltage.
A short to ground means that the current is going to ground before it reaches the component it is supposed to
feed. These are often caused by chafing of the harness to the frame or wires trapped between a bolted
component, and will often blow the fuse on that circuit.
A short to battery voltage (12 Volts) is caused by a live power supply wire contacting an adjacent cable. Note
