Heard a line chief say 'the book is a guide, not a gospel' about a wiring diagram

We were troubleshooting a phantom voltage drop on a Cessna 172's nav system, and he pointed out a footnote about ambient temp affecting resistance that the main schematic didn't highlight. It got me thinking about how often we might miss those little notes. How do you guys make sure you're catching all the fine print in the manuals?

Man, my buddy once missed a tiny footnote about torque specs and nearly stripped a crankcase bolt.

@johnson.ryan How do people even skip the footnotes? Those tiny numbers are the whole game. I treat torque specs like gospel, no joke. Missing one is just asking for a stripped bolt or worse. Your buddy got lucky it was only "nearly".
