Hi,

I think you are on to it now! Any place like that could be the problem.
If you owned a Porsche, you are use to working down low close to ground! (-:)
The door hinge fuse panel is a knee bender all right.
It is susceptible to having moisture problems from rain and snow off the feet too!

Sorry, I interpreted that you trained from a set of established curriculum handed down from design engineers. That stuff can be written from the likes of Microsoft jerks.
You have to train yourself on how to lookup, what the heck their talking about, in three or four places throughout their manuals!
If it weren’t for the like of geeks, fixing their bugs, they should have gone out of business!
My brother did the same things, that you do, for Kodak in Graphic paper printing machines.
But he saw the writing on the wall with digital coming and films disappearing.
He was headhunted to work as a troubleshooter in the plastic stretch film packaging industry.
He travelled all over the U.S., Mexico and Puerto Rico until he retired due to a merger!
He doesn’t miss the air traveling hassles!

I know about teaching, as I did my share for a while. I didn’t like repeating myself by the book, so much! To me it was boring. Those that can teach, teach and those that don’t, find better things that are more giving in other ways!

Good luck hunting!
Phil
