LABCRAFT PROBLEM ON A 1997 DUETTO

Hello i have a problem for the first time; after a few minutes all of the 12 VOLT labcraft lamp stop working  so i check the fuse in the control panel close to the water level indicator  BUT they are ok  i check the other fuse under the bonet and they are ok too   any idea ??   thank you for your help    pascal

You don't give enough info, such as how the other 12V habitation appliances behave, and what happens if you plug in the mains hookup, but at an initial guess: dead leisure battery? Of course, there are other possibilities, but you haven't given us much to work with!

Hello we resolved the problem it was just a fuse on the panel control  but the first time when i check it with my metrix he was ok  but in fact the wire inside was faulty .  thanks   Pascal
