Dave, I did not take your statements as being critical.... I have already said that I do NOT know about electricity... I am trying to figure out more of it.. but most of the time the discussions get large due to the definitions,, which are pretty deep with electricity... One of my biggest pleasures with Diesels is the lack of an electrical ignition system... ...As is probably obvious I mainly repeat things I have read other places.. which does not make them necessarily proper for where I repeat them... that is where more knowledge than I have really helps... I did want people to know that I was not making them up out of whole cloth... even if I might be misplacing them with respect to their viability in a particular setting ..... Greg
