So what is your point,exactly?Am I dragging this thread too long and get under your skin?Previous postings were not just responding to your comments,there were some others who threw in their advices which I needed to respond politely.
A community forum is a place,other than sharing interests,experience...,where members can post questions and learn.There is no such thing as stupid question,the only thing stupid is you do not ask.
I tried to diagnose the problem I had.What is wrong with asking for advice here and there to see whether I am on the right path?Wasn't this you teacher taught you when you were in grade school?Oh ,I forgot,maybe you got taught so much and so well that you became a smartass now.Remember,you still went through the same learning path,no different.
If the Mod says I posted too many speculated questions,no facts(no evidence),I believe he/she would have told me when and where to stop(not where to go).As far as I am concerned,this thread is still open,however,I will stop here because I have already got a earful.
I better off use the time to troubleshoot than to argue with you.
Believe it or not,I can operate a lot of tools better than you could have imagined.A multimeter does not guarantee where you going to end up,period.
