Hi,

This is a stupid question.  

I know when plug a cable into each end of the tester, if the light is on for each wire, that means the cable is good.

But how do you know which end of the cable is bad if the light is out.  I want to test between the wall drop and the patch panel, assume the cable is good,  Lets say I didnt install the wall drop correctly, how would I know from tester point of view?  thx

There are different testers available.

All testers have basic features like continuity, correct pairs.

Digital testers can advise on cable lenghth and aproximate distance to fault(s) (model dependant)

form basic cable tester I am affraid you won´t know which side is bad. But if test shows cable is patched wrong way you should be able to visualy check order of wires inside of cable (one and second part) and see which does not fit
