So I don't routinely get into this level of ham gear assembly...but I find that I am increasingly going there. When I read "DC power connector's negative terminal", I immediately think of + and - rails, and a neutral ground. I do understand that when I look at barrel connector, the icon usually shows a + and - terminal. But it seems to me that the - terminal is really ground...not a negative rail. I can see how, even with my terminology, swapping leads on a power connector can lead to shorting + to ground. So are we really saying that the case is connected to ground, when we say negative terminal? >Let me "flog a dead horse". This whole affair amounts simply to this: I understand the SOE that led to this event....I am only addressing nomenclature. But thanks for succinctly summarizing... ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
