Diagnostics is a lost black art. There is a you tube video for everything. No one want's old school Chilton manuals you can't give them away and they are chock full of diagnostics. Note sentence #2 is satire.
I agree. If you ask someone in a thread if they did "troubleshooting" its almost as if they don't know what that means. If you get them to the point where they have to troubleshoot its like youve ruined their day...
