Could be in a truck or a bus Most are 24v and yes if in a car, most unusual but as usual half the info needed to give a sensible answerAn interesting thread.. but curious as to what type of vehicle the OP is trying to get this to work on. Certainly there are 24 volt (and really old 6 volt) systems but most vehicles are nominally 12 v. If the OP is seeing 24 volt readings from a "normal" ~12 volt system there is some magic happening.
