Fault Finding

Preliminary Electrical Systems Check

A. EARTH CONTINUITY CHECK -
Appliance must be electrically
disconnected - meter set on 

 (Ohms) x 1

scale and adjust zero if necessary.

a) Test leads from any appliance earth point

to earth pin on plug. Resistance should
be less than 0.1 

 (Ohm), check all earth

wires for continuity and all contacts clean
and tight.

B. INSULATION CHECK - Appliance
electrically disconnected, all switches ON.

a) meter set on 

 (Ohms) x 1 scale.

Test leads from L to N in appliance
terminal block. If meter reads «0» then
there is a short circuit.

b) meter set on 

 (Ohm) x 100 scale.

Repeat test with leads from L to E. If meter
reads less than 

 (infinity) there is a fault.

NOTE - Should it be found that the fuse
has failed but no fault is indicated - a
detailed continuity check (i.e. by
disconnecting and checking each
component) is required to trace the faulty
component.
It is possible that a fault could occur as a
result of local burning/arcing but no fault
could be found under test. However a
detailed visual inspection should reveal
evidence of burning around the fault.

START
Isolate appliance
and carry out:
A: Earth Continuity
check.

 Has inlet fuse blown?

Carry out:
C: Polarity check.

Electricity supply
should now be
satisfactory.

Carry out:
D: Resistance to
Earth check.

Inlet wiring
faulty.
Rectify any
fault.

Isolate appliance and
carry out:
B: Insulation check.
Rectify any fault
including replacing
fuses as necessary.
