AC line problems. Message-ID: <1991Feb5.005045.388@miavx2.ham.muohio.edu> Date: 5 Feb 91 04:50:45 GMT Organization: Miami University, Hamilton campus Lines: 30 Hello! A service man, while working on a persistant and difficult problem with some of our new PCs, was grasping for straws and stuck his multi-meter in the AC outlet. He noticed 118v, ok, and then noticed between .2 and .8v between the Neutral and the Ground. He thinks it should be 0v and MAY be a contributing factor to our "problems". (The problems, not to bore you, are intermittent keyboard line failures during bootup on some DEC/TANDY PCs.) Now, one of our guys was checking into it and found that while the Hot was a clean sine wave, the Neutral was a bit "fuzzy". He also noticed that voltage between Neutral and Ground went to zero whent there was no load on the line. What I am asking you, the world, is this BULLSHIT, or NOT???? From my simple knowledge of electricty, I vote for Bull-doo-doo. Before we invest any further energy into this drain, what do you think? Am I right, or not? What is the best/simplest way to check the AC line? *** Bonus points for naming the movie in the subject line *** ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Tom Kreimer --- Miami University --- Oxford, Ohio tgkreimer@miavx1.acs.muohio.edu --- tgkreimer@miavx2.bitnet <-- Use thease!
