Ok, a bit off topic i know! I took the heated jet to bits yesterday, and as rubyjonny said, was full of gunk - smelt very much like fish water :X So i cleaned it all up, redid the connections, bent the terminals so they made better contact.. looked like a new jet. Plugged it in, checked it was getting 12V, which it was. Nothing! No heat at all! I really havent a clue why now!! It doesnt really make a lot of sense to be honest, as the disc that is inside, stops the current getting to the metal, so i dont see the need for it?! :S Anyone any ideas?!
