Sir, I was googling for a Troubleshooting guide and I came across your material. I only say sir out of respect. I know that you work for a living like I did while I was enlisted in the USMC. I wanted to say thank you for that flow chart. It is something that I never found in the depot maintenance manuals that was presented quite like that. Of course, that was 15 years ago before the true cyber revolution. That flow chart is great and I appreciate you making it very available. Semper FIdelis. Michael P.
