To Measure Voltage; Splices - Triumph 2012 Tiger 800 Service Manual

To Measure Voltage:

In the example below, the circu it voltage is being
measured at the bulb positive (+) terminal.

General Information

Splices

Splices are probably the most common cause of wiring
faults after connectors. Splices are made where two or
more wires come together and diverge in different
directions, usually to feed a different circuit.
To locate a splice, it is necessary to peel back the insulation
and examine the splice for its integrity. The most common
fault is where one of the wires at the joint has come adrift
usually causing the circu it it feeds or earths to become
'dead'.
Switches
To check a switch, set the multi meter to resistance/
continuity and probe the t w o pins that form a closed
circuit when the switch is pushed. If the switch is working
correctly, the resistance should register or the meter will
bleep.
Relays
Al l relay cases have a circuit path engraved on them
showing the circu it path across the electromagnet and the
switch. Before m aking any checks, first note the pin
designations, current paths, and whether or not there is a
diode in either circuit path.
