by shaking it by hand lightly. If any abnormal condition is found,
repair or replace.
Wire insulation which is rubbed through, causing an intermittent
short as the bare area touches other wiring or parts of the vehicle.
Wiring broken inside the insulation. This condition could cause
continuity check to show a good circuit, but if only 1 or 2 strands
of a multi-strand-type wire are intact, resistance could be far too
high.
If any abnormality is found, repair or replace.
