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 (Q).
In the example below, the ground circuit continuity is being tested from the battery to
the frame.
• Locate each end of the wire.
• Set the Digital Multi Meter (DMM) to resistance check Ohms.
• Probe each end of the wire.
• If there is continuity, the meter will usually bleep or register the resistance of the
cable.
• A high resistance figure could indicate a dirty or corroded connection.
• If there is a break in the wire, the meter will not bleep or register a resistance.
• By probing the wire in various places, the position of a high resistance or break in
the wire (open circuit) can be narrowed down until it is found.
