my uncles smoker died it's the 800 watt model we took back cover off last nite and there was only 1 black wire going to the element along with the ground the other terminal was empty. i tthought this odd but it was late and didnt look to hard. now i'm lookin this morning and all pics i see have a wire to each terminal. so do we need to go back in for a second look for a missing wire or are the picss i see of a hotter unit? thanks so much
