partially dead electrics

I will find this problem no doubt but could anyone who has sufferred this let me know to save me a lot of time and grief from my wife regards 'are you working on that car again' would be much appreciated.

I came into work in the Cq this morning and all was fine, once here I realised I had left my laptop behind. Doh! Went back to the car to come home and turned on the ignition and...nothing! The engine started and ran thank goodness but virtually anything not engine related is dead. I can hear the ignition Aux relay clicking in but I have nothing. Am lucky the engine started so I could get back home where it resides looking very sorry for itself.
Haven't had chance to check everything but the following is dead. :-
Rev counter, Water temp, Fuel gauge, Centre console gauges, indicators, dash lamps, alternator(ign lamp comes on all the time as obviously no supply on exciter wire).
This is definately still working:- Fuel pump, interior fan, electric windows, stereo,
Will have a full list of what is and is not working once I get home tonight. Hoping its just a wire come off the bottom of the fusebox!
