Default break in cat5

In article ,
scribeth thus
I have 2 cat 5 cables that run from the kitchen to my patch panel.

The cables came loose from a window frame and got steached when
somebody opened a window.

I cut off the first 12 feet of the cables, including the bad bit and
fiited new between the socket in the kitchen and a pair of krone style
joiners which connect to the original wires

I have a cat5 tester and almost had it ready to role but I' have three
wires that are not connected.

I have re-made the joints at the joiners and and the sockets a couple
of times but still cant find the break. Ive also punched down all the
Krone fittings

Is there a tecnique to trace the break to the original or new wiring.

I dont fancy putting RJ45's on the old wires as its a bit brittle and
under the eaves

All i,ve got is a multimeter.

Help and direction appreciated

I suspect its pulled apart somewhere else along the line and if it were
that case you'd need a TDR to find it which is something most people
don't have..


Really? LOL
You almost covered my screen with coffee with that one Tony

However if you have Two decent pairs working then use those for carrying
the signal only the Orange and Green pairs are used for normal 10/100
ethernet use.

You can find out which pairs are OK by doing a simple Ohms test with a
meter .Just short say the Green and Green/White at one end with a bit of
wire then check for continuity on the other end you can also do a check
from each conductor to each other to see if you have any shorts which
sometimes happen when cables have been pulled..

So if say you have a decent Blue pair and the Greens U/S then substitute
the Blue for the Green. Done it before and its worked fine...

Don't use a Green and a Blue wire for instance to make a pair, it might
measure OK but you won't get much of a signal down it!.

Course if its Gigabit or Power over ethernet anywhere then that won't
work and you prolly end up replacing the complete length..
