Topaz Leisure Battery and 12v Fuse Box

Hi, 
I have a 2006 Topaz and am having trouble with the leisure battery. I am trying to recharge it but suspect it may need replacing. The battery is under the bench seat on drivers side, but is covered by a wooden lid. I am struggling to get this lid out due to the seat mechanism. Has anyone got any advice how to get at the battery, do I need to take the wooden front panel off too ?
Also the water pump has stopped working even when charging/hooked up, so I want to check the Fuse (as it was working yesterday). Does anyone know where the 12v fuse box is located for this Topaz model, or particularly the water pump fuse (the owner manual is not helping) ?
Any advice gratefully received.

Top cover has to come off NOT the front panel
two screws along front edge of sliding rail
then fully extend the slider and wiggle the lid out.
All is under there, battery, hab/veh charger, water heater and dump valve, our pump is anyway not sure where the fuse is though.

Thanks for the reply, I will try removing the lid as you suggested

Yhe pump in the Topaz is under the floor of the wardrobe at the forward end. It' a real pain to get at, but simple. Just lots of screws holding wardrobe lining panels thta you need to remove. Keith

A/S put the pump in various places in our previous models, behind fridge, got at via the vent covers, behind/under the tip up sink, acess via toilet room end panel so it can depend on the year of your models build.
In our 2008 build Topaz in the settee box attached the fridge compartment side
