Why does nobody talk about how bad training manuals are for Gulfstream GIVs?

I spent last Tuesday trying to track down a hydraulic leak on a GIV and the manual had me going in circles for 4 hours. Turns out a senior guy walked over, showed me a trick with a paper towel and a flashlight, and I found the leak in 10 minutes. Has anyone else had a training manual that was just useless for real world work?

Man I had a buddy who spent THREE DAYS chasing an avionics fault on a GIV using the manual step by step. Turns out the whole thing boiled down to a loose connector behind the panel that a tech from the 90s had taped up with yellow electrical tape. The manual never mentioned checking for that kind of field repair, but the old guy who showed him pointed at the tape and said "try pulling that off first." Fixed in five minutes. Those books are great if you're building the plane from scratch on a clean bench but they don't account for all the weird stuff that happens in real hangars.

Honestly I gotta push back on this lol. Those manuals are written by engineers for a reason, the paper towel trick is just a hack not something they can put in an official manual. You can't blame the book for being thorough just cause you found a workaround.
