Lost instruments on R reg Megane?

Hi folks, I've recently had to charge the battery on my R reg Renault Megane 1.6 RT and on putting it back I have now lost all instruments...speedo,rev counter, fuel gauge,tempreture gauge etc. I've checked all fuses in car and under bonnet also the ones next to the battery. It starts and runs ok but no instruments. If anyone could shed some light I'd be V grateful! Cheers
