that's just a standard smoke unit and can easily be repaired you just need a new wick and replace the top gasket. as far as the short you said is concerned if there was a short from the element to smoke unit case you would have blown your engine board! the resister or heater element is normally centered inside the smoke unit tank so as not to short to metal unit! would only cost if you do the job Is the cost of the gasket and wick!unless you send to someone to get rebuilt. there not hard to replace!
