How can I fix my fan oven?

When I turn on the main oven everything works fine, but when I turn on the smaller, top oven with grill it trips the fuse box and everything turns off and I have to reset the fuse box.
Anyone know what's going on and how it can be fixed?

done
the grill or base element in top oven is going to earth, the best way to find it is, switch the electrics off to cooker, remove the two wires to the bottom elemet, tape up and switch the power back on try oven , if it does trip replace the wires and remove the wires making note where the colours go to the grill, when it stops tripping, that is the element, there is only 2 elements on top oven, cheers
