I was looking around and found the following web site
http://www.thecircuitdetective.com/
I hadn’t seen this one in particular, but felt that it was well laid out information in an easy to read format.
His Article
"Open Neutral, Hot and Ground; Reversed Polarity"
http://www.thecircuitdetective.com/insp.htm
Was a good read as well, some of this information may be a bit “basic” but, I’m sure that there is information that many of the “crowd” here can benefit from.
