Ever try to teach a computer illiterate (no disrespect intended) how to change anything?
I'm looking for someone with knowledge of electric fields, and this thread looked like as good a place to start, as any.
My husband ran into a problem with a crane on an oil tanker that was running 4000 volts of electricity from somewhere. It has been determined that the power wasn't being generated by anything on the ship, but they never found the source, and the power declined at sundown. But I'm concerned that it could happen again at the same dock, and maybe kill someone the next time.
