To Check Continuity - Triumph Scrambler 1200 XC Service Manual

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 that it is also possible for a 5 Volt sensor reference voltage to
short to an adjacent circuit, which can also cause electrical failures and DTCs
(Diagnostic Trouble Code) to be stored.
When tracing a wire that is suspect, carefully check the circuit diagram before
starting. Remember:
a wire may diverge at a splice and go off to feed other circuits. If these circuits are
working, check for wiring faults from the splice onwards.
the circuit diagram is not an accurate guide to the actual location of the parts
when fitted on the motorcycle. It is a schematic diagram of the circuits.
particularly where engine management items are concerned, the circuit is only
completed by the ECM. If the ECM is not connected, the circuit may register as
open.

To Check Continuity:

Ensure the circuit being tested is switched off before measuring continuity.
Damage to the Digital Multi Meter (DMM) may result from testing a 'live' circuit with
the meter set to resistance (Ω).
In the example below, the ground circuit continuity is being tested from the battery to
the frame.
