Open circuit or
short circuit
Explanation
(2a) This indicates a high-resistance fault, which
restricts the amount of current flowing through
the circuit. Possible faults include a poor con-
nection, wet cables, or a line extender failure.
(2b) This indicates a partial short circuit.
Break the circuit down into sections and check each
section for continuity.
