Cable Faults
Checking for
breaks:
Checking for
shorts: Disconnect all components from the cable run that
you wish to test.
Place a Shorting Link on the connector at one end of
the cable run and at the other end using a multi-meter
check the resistance between every conductor on all
of the connectors on that run.
Zero resistance for each of the conductors between
the shorting link and multi-meter indicates that there
is no break.
Infinite resistance indicates there is a break in the
cable run and you may need to move the multi-meter
or shorting link to another location to pinpoint the
section of cable in which the break occurs.
Disconnect all components from the cable run that
you wish to test.
Using a multi-meter check the resistance between
every conductor on any of the connectors on that run.
Low resistance indicates there is a short somewhere
on that cable run. If the cable run has 3-way
junction boxes on it you will need to remove the
scotchloks connectors from the conductors showing
the short and test each section of cable individually
until the short is located.
