To Measure Voltage:
In the example below, the circuit voltage is being
measured at the bulb positive (+) terminal.
•
Voltage Check
Turn the circuit to be tested 'ON'
Set the Digital Multi Meter <DMM> to Voltage
check N). Ensure the multi meter is set to de
volts for direct current circuits <most circuits)
or ac volts for alternating current circuits
(typically alternator output voltage tests>.
Set the range of the DMM to the range best
suited to the voltage of the circuit being
tested (typically
20
volts for most DMMs>.
Refer to the DMM manufacturers
instructions.
Connect the black (ground) lead of the DMM
to a reliable ground connection (usually the
battery or frame ground>.
Locate the positive terminal of the wire or
component to be tested.
connect the red (positive) lead of the DMM
to the positive terminal.
Read the voltage from meter.
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 circuit it feeds or earths to become
'dead'.
Switches
To check a switch, set the multimeter to resistance/
continuity and probe the two 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
All relay cases have a circuit path engraved on them
showing the circuit path across the electromagnet and the
switch. Before making any checks, first note the pin
designations, current paths, and whether or not there is a
diode in either circuit path.
Diode
86
87
Electromagnet
30
Make continuity checks across the electromagnet first,
usually from pin
, 86
(positive> to pin
85
<negative>. If a
diode appears in the circuit use the diode check on the
multimeter <volts scale) in the direction of current flow. If
there is no diode, use the resistance check facility. An
open circuit or unusually high resistance value indicates a
faulty relay.
To check the switch side, apply a 1 2 volt supply between
pins
86
and
85.
With the supply connected the relay
should be heard to click and there should be continuity
between pins 30 and
8Z
An open circuit indicates a faulty
relay.
