Hello Joseph,

Could I refer you to this web site.

<http://www.southwest.com.au/~jfuller/rj45/rj45.htm>

Whilst it does not have the mods that I did in order to check crossover 
cables it would form the basis of a tester.

My thanks to the other guys for the PP3 battery info.  Although any 4.5 
volt to 9 volt battery would work, the resistor values would have to be 
altered a little for lower voltages.  You could, at a pinch use a 2032 
coin battery, if you wanted.  However you may have trouble seeing the 
LEDs light up with long cables.

If you want a description of my tester let me know.  That goes for 
anybody else as well.
