GringoPhil: thanks for the compliment. I used to teach aircraft system troubleshooting and also problem solving in a manufacturing environment. People here helped me when I first had my coach and I'm glad to return the favor when I can. We own very complex vehicles and if we are to solve the problems ourselves (and I certainly respect those that choose to have others do it for them) it really helps to have many minds applied.

I will add that as I construct my suggestions I do so in a way that I hope helps educate the reader on the thinking process of problem solving/troubleshooting. I believe the more we understand how to think about the problems the more problems we will be able to solve and the more proud we can be of ourselves for what we can do.
